The rinser is available for 12 or 24 bottles. It can be fitted on top of a cement/stainless steel/plastic tank. The rinser consists of a stainless steel pipe and tray. The rinser is connected to a water source like overhead tank. The ball valve on the machine is in closed position. 12/24 bottles are kept up side down in the 12/24 rubber cups provided. Then the ball valve is opened. Water jets into each of the bottles. The bottles are thus rinsed of dust particles or soap water, the rinsed water falls back into the tank and can be filtered and re-pumped. Approximately 24/48 bottles can be rinsed per minute. If there is no overhead tank, the rinser can be supplied with a pump. The pump need not be switched on & off every time the bottles are changed. A by pass system with a non-return valve ensures that the pump does not get overloaded. This unit requires very little maintenance.
