'systems from CWC Ltd work by spraying cm an application of diluted chemical which, after a one minute delay, is then rinsed off under high pressure.
Two basic configurations are available—the first is a drivethrough system where the vehicle passes under two arches with the first applying the cleansing agent and the second doing the rinsing. The other arrangement consists of a moving gantry which passes back and forth over the vehicle.
All the units feature a prewired and pre-plumbed power pack which requires no special building to house it. This totally 'enclosed power pack houses the rinse and chemical application pump, chemical metering pumps, control panel, water and chemical storage tanks. All are protected by a thermostatically controlled heater for winter conditions.
For the drive-through operation the chemical and rinse sprays are controlled by floor treadle switches activated by the front wheels of the vehicle. When the vehicle drives slowly through the rinse arch the system shuts itself off automatically after one minute.
The roll-over version uses the same power pack but in this case an overhead gantry automatically travels the length of the vehicle.
