Remote monitoring of vehicle washing facilities allows a facility operator to more efficiently manage each site, particularly when combined with environmental conditions that influence the rate at which individual chemicals are used. Accurate chemical exhaustion times can therefore be predicted and communicated to the operator, and wash sequences and parameters may be altered in accordance with such environmental parameters. For example, information related to the composition of soil on a car may be monitored and used to alter the chemicals used in the wash cycle for that car. Other environmental conditions may include without limitation weather conditions, road conditions, types of vehicles, mechanical system status, vehicle temperature, etc.

Monitoring and controlling processes at a vehicle wash facility

A water-driven jet or venturi extraction means is used to remove, capture and cool the hot, highly humid air created within commercial dishwashers during a wash rinse or sanitization cycle. A cold water spray is used to create a pressure reduction zone which serves to draw in hot, highly humid air from the dishwasher. Water vapor cools and condenses on contact with the cold water spray within the venturi. The invention also serves to help vent the dishwasher. Cool, fresh air is drawn into the dishwasher while the hot air is drawn into the venturi.

Removal of heat and water vapor from commercial dishwashing machines

A device for generating a liquid detergent concentrate from a solid detergent is provided. The device includes a solid detergent reservoir for holding solid detergent, a stock solution reservoir for holding stock solution, and a hot water heater for controlling the temperature of water used to generate the stock solution from the solid detergent. A method for generating a liquid detergent concentrate from a solid detergent and a method for washing a vehicle are provided.

Device and method for generating a liquid detergent concentrate from a solid detergent and a method for washing a vehicle

The present invention relates to a method for applying a detergent use solution to a washing surface of a motor vehicle, including the steps of: (a) providing a liquid detergent concentrate that includes an active ingredient level from about 0.1 wt. % to about 15 wt. %; (b) introducing the liquid detergent concentrate into a water stream to provide a detergent use solution that includes an active ingredient level from about 0.03 wt. % and 1 wt. %; and (c) applying the detergent use solution to a washing surface of a motor vehicle. In addition, the present invention also relates to a method for washing a washing surface of a vehicle, wherein the method includes: (a) providing a liquid detergent concentrate having an active ingredients level from about 0.1 wt. % to about 15 wt. %; (b) introducing the liquid detergent concentrate into a diluent stream to provide a detergent use solution; and (c) applying the detergent use solution to a washing surface of a vehicle wherein the detergent use solution has a relatively constant active ingredients level over the entire washing surface during a wash cycle.
