YHWS pressurized washer system is specially designed for YUHUA explosion proof PTZ cameras.
The whole system is composed of stainless steel water tank, explosion proof solenoid valve, spray nozzle and explosion proof junction box.
When used, firstly fix the spay nozzle on the PTZ window with its bracket, pressurize the water tank manually with its handle, and then connect the PTZ camera and solenoid valve with explosion proof junction box. The relay output from PTZ will control on/off of the valve and water will come out from the spray nozzle to clean the window.
The vertical distance between PTZ camera and water tank can be up to 25~30 meters. When the pressure is not enough, the water tank needs to be pressurized.
When the temperature is less than 0 Celsius, the anti-freeze liquid is required for water tank.
Bracket for valve can be fixed on the PTZ camera bracket with screws.
220VAC power supply
