REMOTE VACUUM REGULATOR
Exclusively designed remote vacuum regulator is a vacuum-to-open and normally closed. It continuously monitors vacuum and regulates gas flow to a closely controlled value. When located as close as possible to the source of gas supply, the risk of handling gas under pressure is reduced to a minimum.

INJECTOR
Capacities up to 40 Kg/hr of chlorine have a fixed throat. Capacities of 50 kg/hr chlorine and above are equipped with variable orifices, which may be achieved by a throttle valve on injector, so that water consumption may if necessary reduced to a minimum. Water passing through injector should reasonably clean.

Injectors are selected to create vaccum and to limit Chlorine solution strength to 3500 rpm at 25C or 2500rpm at 40C at hogher concentrations molecular Chlorine breaks and fumes at the point of application, causing inefficient mixing of chlorine.

FLOW METER
IEC Chlorinator Model R-103 have flow meters for a maximum capacity of 1, 2, 3 ,4, 5, 10, 20, 30, 40, 50, 75, 100, 150, 180 & 200kg/hr as std models and 300kg/hr as custom built models of chlorine gas. Feed range is 20:1 for any flow meter. The flow meter has an accuracy of ± 4% of the indicated flow. The float and packing are made of PTFE.

The system is provided with a check valve, vacuum relief valve, and emergency drain relief valve. Water passes through the injector to produce vacuum. This vacuum opens the check valve and extends the vacuum up to the remote vacuum regulator.

The chlorine supply under pressure is reduced to a constant vacuum at the remote vacuum regulator. The gas under vacuum is controlled at the gas flow meter and flow control valve to differential regulator which maintains a constant vacuum differential. The chlorine solution is then discharged from the injector to the point of application.
