Fleet Wash Chemical and Equipment Technology

The DyChem Fleet Wash System incorporates a two step procedure that we designate as "shock treatment". The first step employs the use of a low pH product, which is applied to the entire vehicle surface. After the first step, or low pH application takes place, the vehicle travels to the second arch. Here, an alkaline product is applied to neutralize the low pH that was applied at the first step. The rapid neutralization at the second arch is the chemical "shock" result. The chemical reaction at this point releases the statically held road film and dirt from the surfaces of the truck. Conventional cleaning methods can not produce this phenomenon. The surfactants and wetting agents contained in the alkaline product not only neutralize the first step product (resulting in a neutral pH a slightly alkaline solution ready for the drain), and releases the static road film; but removes exhaust smoke trails and oil associated foreign, surface dirt. The released soil and spent cleaning solution are flushed from the vehicle's surface with high volume, impinging rinse, immediately following the second cleaning step. There is no need for further dwell time. The entire wash and rinse cycle for a tractor and 48 foot trailer takes only 45-60 seconds and consumes 125-150 gallons of water. Short vehicles will take less time and consume less water.

General Equipment Specifications:

The DyChem Fleet Wash System is a fully automatic system that utilizes only the driver for the operation. Vehicle speeds of 500-600 RPM must be maintained throughout the drive-thru system operation. Chemical solution and rinse are applied to the vehicle only as long as it remains in the individual application zone. The use of micro-limit switches for pump activation enables efficient application of pre-diluted chemical solutions with no waste. Each segment of the cleaning arch system can be isolated to run independently, adding versatility to the wash program. The "low use cost" are more noted when controlled speeds mentioned above are employed.

In addition to the description of the Fleet Wash System, here are electrical and water requirements.

Minimum Water Requirements:

1 1/2 inch water line at 50 psi
Sewer line 4 inch at 300 gpm

Please note that the pressure provided for chemical and rinse application is done with pumps.
