1. Eco-Friendly Steam Wash
1) How is the Optima Steamer different from other steam cleaning machines?

The Optima Steamer is designed with environment and user safety in mind. After many years of trial, we have come to the current Optima Steamer model. 

The Optima has the optimal operating preset steam pressure and temperature values based on our research. It also has multi-stage safety features to ensure that the Optima Steamer does not go out of control under any unexpected situation.

Please learn more about our technology.


Moreover, SJE Corporation takes 쐀eing green seriously. We are always looking for a way to 쐅reenize everything about using the Optima Steamer. We continue to research and develop products and accessories to fulfill our clients needs worldwide.

http://www.sjecorp.com/system/usSupportFAQ#171
2) Is the Optima Steamer certified by any international standards (CE, UL, etc.)?

Yes, the Optima Steamer is currently CE (Conformit챕 Europ챕enne: European standard) certified (for Low-Voltage Directive and Electromagnetic Compatibility) by T횥V (Technischer 횥berwachungsverein:  Technical Inspect Association of Germany), Gost (均棘곎꺪닉겉곎궿꽥둔싻싼뗊 곎궿겆싻닉겉:  State Standard of Russia) certified, cTUVus (Canada & U.S.) certified by NRTL (Nationally Recognized Testing Laboratories). cTUVus denotes compliance to U.S. and Canadian National Standards.
The Optima Steamer is the only steam cleaning machine of the same industry in the world that holds all CE, Gost, cTUVus certifications.

SJE Corporation is an ISO 9001 (International Organization for Standardization for quality management systems) certified manufacturer.

http://www.sjecorp.com/system/usSupportFAQ#172
3) Does the Optima Steamer have a product liability insurance coverage?

Yes, we have a PL insurance to protect our Optima Steamer users.

http://www.sjecorp.com/system/usSupportFAQ#173
4) What kind of water is recommended to use with Optima?
We recommend water that does not contain much of sodium, iron, calcium and other minerals.

For most countries, tap water is sufficient. But if you know that tab water or subterranean water in your area has high mineral content, you should take special cautions.

Using water which contains minerals, requires frequent cleaning and scale removal.

To prevent sever scale problems, we recommend users to add the provided water treatment to the water tank. The water treatment we supply is a water conditioner/softener liquid that helps prevent hardened scale inside the boiler vessel. Using water above 5째C (40째F) is recommended.
http://www.sjecorp.com/system/usSupportFAQ#174
5) How much water is consumed to wash a car?
It takes about 2~5 liters (0.5~1.3 gallon) of water depending on the user셲 skill level and how big and dirty the car is. Also, the climate of the car wash site affects the water consumption rate. For example, a user in a very dry and hot climate should expect to consume more water because more water content of the steam is evaporated into the atmosphere before being in contact with the car surface.
http://www.sjecorp.com/system/usSupportFAQ#176
6) Is steam wash as effective as using water when cleaning a very dirty car?
The Optima Steamer effectively washes various surfaces using  steam with high temperature (operational steam temperature : below 100째C /  212째F) and relatively low yet powerful enough amount  of steam pressure. The heat of the steam helps break down dirt and mud on car surface very quickly and efficiently. Also, all Optima models are equipped with a moisture control valve that can add more moisture to the steam for a faster car wash. If you open up the moisture control valve, the Optima Steamer can spray up to 1200 cc/min per spray gun. This helps washing very muddy cars more quickly, but more water will be consumed.
http://www.sjecorp.com/system/usSupportFAQ#178
7) Do I need a wastewater facility or any special permits to use these machines?

Every country and every municipality has different regulations.

The best way is to check with your local government.

For most cases, however, a car wash operation using Optima Steamers does not require any water reclaim or wastewater filtration system. This will save you much money and time when setting up your own business in the beginning.

In addition, the Optima Steamer can be used for mobile car wash or cleaning businesses.

 

http://www.sjecorp.com/system/usSupportFAQ#179
8) Are these systems of steam cleaning and wash being used on a commercial basis?

Yes they are. Many of the systems are being used in car wash and detailing businesses, the food service industry, hospitality industry, and government institutions including military, schools and universities. The use of  steam cleaning system improves indoor air quality, reduces the physical effort involved with cleaning and provides a more thorough approach to cleaning. Because the use of chemicals is reduced and because water does not involve the regulatory requirements that many cleaning chemicals require, the system requires less management time and reduces paperwork.

http://www.sjecorp.com/system/usSupportFAQ#246
9) Why haven't I heard more about steam cleaning or steam car wash?

If you reside in North America, the answer is very simple. In terms of domestic steam appliance, while having been available in Europe, Asia and the Middle East for many years, is just now being introduced into the North American market. Because the electrical power supply in North America is different from the electrical system elsewhere in the world, the products had to be re-engineered for use in North America or countries with 115-120 Voltage. The late arrival of steam cleaning concept in North America naturally prevented North American residents from having exposures to various commercial and industrial use of  steam cleaning such as car wash, sanitation, weed control and more.

    5) Which Optima Steamer model is best for me?
    To find out which model best suits your needs, please see Which Model Do I Need?
    http://www.sjecorp.com/system/usSupportFAQ#200
    6) What is the lifetime of the machine?
    The Optima Steamer is built to last long. It is the water quality that shortens the lifetime of the machine. But we expect that the machine will last for a decade if used and maintained as instructed.
    http://www.sjecorp.com/system/usSupportFAQ#201
    7) Is the Optima Steamer CE certified?

    Yes, the Optima Steamer is currently CE (Conformit챕 Europ챕enne: European standard) certified (for Low-Voltage Directive and Electromagnetic Compatibility)by T횥V (Technischer 횥berwachungsverein:  Technical Inspect Association of Germany), Gost (均棘곎꺪닉겉곎궿꽥둔싻싼뗊 곎궿겆싻닉겉:  State Standard of Russia) certified, cTUVus (Canada & U.S.) certified by NRTL (Nationally Recognized Testing Laboratories). cTUVus denotes compliance to U.S. and Canadian National Standards.

    The Optima Steamer is the only steam cleaning machine of the same industry in the world that holds all CE, Gost, cTUVus certifications.

    SJE Corporation is an ISO 9001 (International Organization for Standardization for quality management systems) certified manufacturer.

    http://www.sjecorp.com/system/usSupportFAQ#202
    8) Will Optima be compatible with voltage and current standards in my country?
    Yes, your orders will be prepared in one of the following standards: 115V 60Hz; 230 V 60Hz; 230V 50Hz; 380V 60 Hz, and other customized standards are also available upon request. Please be sure to double check with us when ordering.
    http://www.sjecorp.com/system/usSupportFAQ#203
    9) Do I need a wastewater facility or special permits to use these machines?
    Every country and every municipality has different regulations. The best way is to check with your local government. For most cases, however, a car wash operation using the Optima Steamer does not require any water reclaim or wastewater filtration system. This will save you much money and time when setting up your own business in the beginning. In addition, the Optima Steamer lets you run a mobile car wash or cleaning business.
    http://www.sjecorp.com/system/usSupportFAQ#204
    10) How noisy are the machines in operation?

    Compared to conventional pressure washers, Optima Steamer has very low noise level.

    The noise occurred from spraying steam is usually about 95dB.

    Fuel run models such as DM and DMF have 70dB of noise when the boiler is activated. However the machine is programmed not to idle, which means the boiler is activated only intermittently.

    http://www.sjecorp.com/system/usSupportFAQ#205
    11) Based on what your competitors claim, your machine uses more water than their machines. Is this true?

    If you are looking for a professional washing machine, you need to take a good look at how much washing power a machine has.

     

    Washing Power = Pressure x Flow rate

     

    In other words (in a steam wash machine),

    Washing Power = steam pressure x steam flow rate (=water consumption rate)

     

    Considering that the steam pressure typically range around 8 bars in many steam car wash machines, steam flow rate is what determines the washing power.

    Many competitors claim that you can wash a car with a glass of water with their machines.

    We insist that is simply impossible if you are talking about a real car wash.

     

    The reality is that the more powerful wash, the more water you consume.

    We have studied and tested different water consumption levels, and we believe that 8 bar of pressure with steam flow rate of 600cc is the most adequate water consumption level for commercial car wash while maintaining the operation green (minimal water usage).


     

    We inform our clients that they will need 2L of water to wash a car if the operator is skilled and the car is moderately dirty. But if the operator is untrained or if the car is very dirty/muddy, then you will need much more water ( up to 3 or 4 L).

    12) Some of your competitors are offering the steam machine equipped with a vacuum cleaner. How does the Optima Steamer measure against those machines?

    A machine equipped with both interior and exterior cleaning will show you its limits.
    To be an effective exterior car wash equipment, the machine needs to have a certain pressure and volume (flow rate) ) and we assure that you will not find a model for both interior and exterior car cleaning with sufficient steam pressure and volume. 
    We offer different models which have both steam injection and extraction, but we do not recommend those for exterior cleaning. They are specifically designed for interior cleaning and indoor cleaning tasks.

    For professional cleaning services, we recommend that you use two machines in order to acheive sufficient cleaning result and  satisfaction of clients.
    We do care about feedbacks and demands from our clients and (potential) customers, and we continuously research and develop to meet those expectations

    13) Is it possible and is it recommended to add waxing detergent to the machine system ?

    Actually we do not use wax in order to help old painting to have a better shining.
    It is usually used to protect the gloss of car surfaces (usually polished or new cars are treated with wax).
    Wax treatment is usually to do after washing car (it is same for steam or water car wash).
    If you use wax during a car wash, you will play a role in environmental pollution moreover you won셳 be satisfied with the result. 


    In fact when you boil water, pure water will evaporate and  other substances in water will settle at the bottom of the Boiler.  This chalky deposit caused by water evaporation is called the lime scale. The lime scale in the boiler is the main cause of sensor mal function and life span reduction of the boiler. So in principle we do not recommend adding wax.
    We are currently working with a chemical company to come up with a solution to put an end to this scale problem.

    2) Can I use the Optima Steamer where there is no electricity access?
    All Optima DM series (diesel-run) models are virtually mobile. Diesel-run models require  electric power of 350 watts. You can either accompany batteries and an inverter (i.e. connect to a vehicle battery) or a portable generator.
    http://www.sjecorp.com/system/usSupportFAQ#208
    3) Can I use the Optima Steamer for interior (car) cleaning?
    Yes, you can utilize it for many interior cleaning tasks such as carpet cleaning, sterilizing, deodorizing, air duct cleaning, removing stains of seats and upholsteries, and more.
    http://www.sjecorp.com/system/usSupportFAQ#209
    4) What other accessories do I need to optimize the results?
    For car wash, we recommend our customers to purchase super absorption mops and micro-fabric polishing towels along with the Optima Steamer purchase. However, your accessory purchase decisions should be based on the application. Please see the Accessories page for more information.
    http://www.sjecorp.com/system/usSupportFAQ#210
    5) Can I use detergent, wax, degreaser, etc. with the Optima Steamer?
    Although the Optima Steamer is an efficient chemical-free cleaning equipment, there is a way to integrate detergent into the steam wash. The Optima Steamer comes with one sample spray bottle. You can simply connect it to the gun셲 nozzle. See how a spray bottle works in the Videos page.
    http://www.sjecorp.com/system/usSupportFAQ#211
    6) What kind of water is recommended to use with Optima?
    We recommend water that does not contain much of sodium, iron, calcium and other minerals.
    For most countries, tab water is sufficient. But if you know that tab water or subterranean water in your area contains high mineral content, you should take special caution. Using water which contains minerals, requires frequent cleaning and scale removal.

    To prevent sever scale problems, we recommend users to add provided water treatment to the water tank. The water treatment we supply is a water conditioner/softener liquid helps prevent hardened scale inside the boiler. Using water above 5째C (40째F) is recommended.
    http://www.sjecorp.com/system/usSupportFAQ#212
    7) How long does it take to wash a car with Optima?
    Using one(1) Optima DM series, two(2) people (two steam guns) can work on one car at the same time. In this scenario, two skilled steam car washers can effectively wash the exterior in 10 minutes. Of course, the time may vary depending on the vehicle size and how dirty it is. If a single person is working on each vehicle, it will take about 20-30 minutes per vehicle depending on the person셲 skill level and the size of the vehicle.
    http://www.sjecorp.com/system/usSupportFAQ#213
    8) How often is refilling the water tank required?
    The water tank holds 20 liters of water. However, the low level sensor in the water tank will go off before being able to use up all 20 liters. You should expect to refill the water tank after every 4-6 washes by average.
    http://www.sjecorp.com/system/usSupportFAQ#216
    9) How much of fuel does it take to wash one car (DM Series)?
    The fuel efficiency is at its highest when used continuously. The fuel tank holds 20 liters (5.28 gal.) of diesel. It takes about 0.3 - 0.5 liters [0.07-0.13 gal.] of diesel to wash each car depending on the user's experience level and the size of car. With a full tank, you should be able to wash up to 40 cars, however you will have to refill the tank after washing 30 cars(after 15-16 liters of consumption), because of the low level sensor in the fuel tank.
    http://www.sjecorp.com/system/usSupportFAQ#217
    10) How long do I have to wait to wash the next car after one wash?
    There is absolutely no waiting period between washes. The machine is designed to activate the pump automatically to have enough steam ready for wash at any given time. In fact, the machine셲 fuel-efficiency is at its highest when used continuously. There is two minutes of preheating time in the very beginning of a day.
    http://www.sjecorp.com/system/usSupportFAQ#218
    11) Is steam wash as effective as using water when cleaning a very dirty car?
    The Optima Steamer effectively washes various surfaces using the high temperature and relatively low, but effective amount of steam pressure. The heat of steam helps to break down dirts and muds on car surface very quickly and efficiently. Along with that, all Optima models are equipped with a moisture control valve that lets users increase the water flow rate for a quicker wash . If you open up the moisture control valve, the Optima Steamer can spray up to 1200~1500 cc/min per spray gun. This helps washing very muddy cars more quickly, but more water will be consumed.
    http://www.sjecorp.com/system/usSupportFAQ#221
    12) How many hours per day can I use Optima?
    Optima can be used without stopping for hours 24 hours or longer. In fact, it is more cost-effective if operated continuously without stopping.
    http://www.sjecorp.com/system/usSupportFAQ#222
    13) How many cars can it wash per day?
    With one Optima DM series model, a two-person team can expect to wash about 40-50 cars in 12 hours.
    http://www.sjecorp.com/system/usSupportFAQ#223
    14) What is the operational cost for washing 1 car with an Optima DM Series model?
    Costs of fuel, water and labor vary from place to place. To wash an average sized vehicle, it takes about 3~4 liters (竊1gallon) of water, 350mL (0.09 gallon) of diesel, and 20 minutes of manpower.
    http://www.sjecorp.com/system/usSupportFAQ#225
    15) Will steam damage paint on cars?

    No, it will not if used correctly.

    Paints made for automobiles are highly weather resistant and supposed to endure extreme cold and heat. Steam is a form of gas. The very second steam is exposed to the atmosphere, the temperature of steam drops exponentially. In general, the temperature of the steam on the washing surface is well below 100째C (212째F), but the temperature largely depends on the distance between the steam gun셲 nozzle tip and the surface.

    The Optima Steamer셲 steam pressure is preset at 8 bars (116 psi). This is a relatively low pressure rate, but powerful and sufficient enough to wash various surfaces clean and efficiently.

    16) Indication of Electric Power Supply - Indoor and Mobile (Portable Electric Generator, Car Battery with Inverter)

    Optima Steamer is controlled by fully automated system and every automatic control system requires Electric Power Supply.
    If any problem occurs the system will recognize it automatically and give users signal (via alarm or blinking) or even stop the machine with arising safety concerns.

     

    Electricity is to be gained through the following three channels (methods).

     

    1. Using Indoor Electricity

    -       Get access to the electricity which being supplied to your factory or building

     

     

     

     

     

    2. Using a Portable Electric Generator

    -   Using portable generator will require higher investment in the beginning but it is surely economical

         in long-term perspective

    -       1kV 3kV Generator

    -       Appropriate for mobile use of Optima Steamer

    -       Ca. 1kV is required to run one Optima Steamer

     

     

    Generally various Generators are available almost in every market.

     

     

     

    3. Using Car Battery

     - You can use your car battery with inverter to run Optima steamer

     

     

     Using additional battery (& battery charger) along with the original car battery

    6. Maintenance (Optima Steamer Series)
    1) What is Watercon, and do I need it if I want a chemical-free wash?
    Using water which contains minerals, requires frequent cleaning and scale removal. To prevent sever scale problems, we recommend users to add the provided water treatment (Watercon) to the water tank. Watercon is a water conditioner/softener liquid that helps prevent hardened scale inside the boiler. It helps boiler generate pure steam, and thus safe on the car surface.
    http://www.sjecorp.com/system/usSupportFAQ#177
    2) How often do parts need to be replaced?
    Some consumable parts such as water, fuel filters, water level sensors, fuses, etc. must be checked frequently and should be replaced if needed. Water and fuel quality (for fuel-run models) can greatly affect the lifetime of boiler and other important parts of the machine. Maintaining the boiler free of scale and soot problems will prevent from frequent part replacement.
    http://www.sjecorp.com/system/usSupportFAQ#228
    3) Can I use chemicals ( i.e. wax, degreaser, cleaner,,) with the Optima Steamer?
    Although the Optima Steamer is an efficient chemical-free cleaning equipment, there is a way to integrate detergent into the steam wash. The Optima Steamer comes with one sample spray bottle. You can simply connect it to the gun셲 nozzle. See how a spray bottle works in the Videos page.
    http://www.sjecorp.com/system/usSupportFAQ#224
    4) If there is no distributor around me, what should I do when I need service?

We may inform you a specific brand or a product you can obtain yourself in your local market. Using unapproved parts or accessories may damage the machine.
    http://www.sjecorp.com/system/usSupportFAQ#226
    6) How often is maintenance required for the Optima Steamers?
    Daily maintenance items include adding water treatment to the water tank and releasing remaining steam after use. Monthly maintenance items include checking water and fuel filters, draining water and fuel tanks, and checking water probe sensors. Once in every 3 to 6 months, we recommend a boiler combustion cleaning and scale removal of the boiler. All of the maintenance items are listed in the user셲 manual with step-by-step instructions.
    http://www.sjecorp.com/system/usSupportFAQ#232
    7) What are the precautions to take if used in cold weather?
    Freeze prevention is one thing you should take care of when using the Optima Steamer in cold regions.   A freeze can result in rupture and damage important parts of the machine. Thus, it is very important to remove remaining water from the machine system after daily use. Room temperature is perfect for storage. If machine is left in low temperature unexpectedly, and a freeze is suspect, let it defrost itself before operating again. Detailed information is included in the product manual.
    http://www.sjecorp.com/system/usSupportFAQ#219
    8) What are the precautions to take if used in hot weather?
    There is no safety related issue when used in hot weather as the machine generates heat itself. However, it may be necessary to adjust moisture amount of the steam by using the humidifier valve for more effective car wash. Detailed information is included in the product manual.
