Water Wash System
OPTIONAL
Water Wash Misty System
The VIANEN Water Misty system reduces the risk of fire caused by sparks during the cooking
process, especially from charcoal grills.
The VIANEN Water Misty system can be applied to the Water Wash system. A separate piping
system for the required cold water is integrated into the canopy.
The nozzles of the Water Misty system release a continuous fine mist spray of water during the
cooking process. This highly efficient method of filtration also changes the grease from its
gaseous state to condensed grease particles in the cold water mist.
The contaminated water containing the effluent is collected in the same dedicated channels
and runs off to the drainage system.
The system can also be equipped with the following options:
.
.
Grease Shield Defender for automatic grease removal.
Water Recycling System.
For more information refer to our brochure Water Misty Canopy with recycling systems
The VIANEN Water Misty system operates on a constant cold water feed to generate the
water mist. To safeguard the operation of the system the first 3 – 4 m of the extract ductwork is
watertight and a moisture eliminator is mounted on top of the canopy.
The controls of the Water Wash Misty system is integrated in Water Wash control cabinet.

which also features a digital display to monitor the system. A mains hot water feed is
required (to be provided by others) to a ¾” water connection. The recommended
minimum water supply temperature is 65°C.
