The system includes 3 x R6S Rainguns mounted above the refuse which is being recycled the systems is connected to the existing mains water supply with the necessary WRAS approved double check valve installation.

Site No2 Wolverhampton Site (Automatic System)
MWT supplied and installed 2 x R25S Rainguns mounted upon the top of the picking shed with a throw of 30mtrs in still air condition in high winds this will change accordingly. Each Raingun was fitted with a 24v AC solenoid valve and each Raingun will be operated separately on a 2 station controller. 7.5kw three phase pump will be fitted at the existing storage tank which will be controlled via a pressure switch, 90mm HPPE mains will run from the pump to the Rainguns.
The system will operate as follows:
The controller will open the solenoid valve thus dropping the pressure in the pipe from the pump unit which in turn will start the pump (From the pressure switch) when both Solenoid valves have closed the pressure in the pipework will rise and therefore will stop the pump which is now on standby until the system is required again.
