Bencho Model KRG 105 Wall Mounted /Cylinder Mounted Gas Chlorinator
The KRG Model 105 Wall Mounted/Cylinder Mounted Chlorinator is a vacuum operated, solution feed chlorinator, designed to provide continuous and constant measured quantity of gas while in operation. It is suitable for use with Chlorine.Sulphur Dioxide or Ammonia Gas, intermittent “Stop/Start” control or automatic “shut off” can be achieved by interruption of the motive water supply. These units are ideally suited for water and water treatment applications. Food Processing, Swimming Pools, Recirculating Water Systems, Control of Algae and Odour.
Design Feature
Vacuum operated assures safety for plant operating personnel and equipment. Low initial cost of installation and maintenance, rugged corrosion resistant construction all contribute to the most economical chlorination system available.
Principle of Operation
The Chlorine gas from the cylinder enters the chlorinator where it is filtered to remove any foreign material which might be present. Water under pressure flows through the ejector at high velocity and causes a vacuum which opens a spring opposed check valve opens, a vacuum signal is carried to the vacuum regulator, mounted on the cylinder. This vacuum causes the diaphragm to open the chlorine inlet safety valve to admit the gas into the regulator. The spring-opposed diaphragm regulates the vacuum at this point.
The gas passes through the flow meter and the rate control valve and then to the ejector where the chlorine is thoroughly mixed and dissolved in the water and carried to the application point as a solution. If the water supply to the ejector is stopped, or the operating vacuum is lost for any other reason, the spring loaded gas inlet valve immediately closes to isolate the chlorinator from the gas supply, any gas, under Pressure which might enter the regulator is vented form the system through built-in pressure relief valve, If the source of chlorine gas is exhausted or the gas line plugged and excess vacuum valve in regulator closes to prevent any moisture being pulled back into the regulator or the gas supply lines. The ejector is provided with a diaphragm operated back check valve to insure that water does not leak back into the regulator when the system is shut down. The ejector is designed either for mounting directly in the pipeline or wall mounting type.
Materials of Construction
Components exposed to dry gas under pressure are chlorine resistant alloys.ABS, UHDPE, PTFE, PVC,Silver, Tentalium and extra heavy duty borosilicate glass are used in the construction of the chlorinator and ejector.
Optional Accessories
Also available when required, are alarm devices, pressure reducing valves, gas manifolds, booster pumps, and solution change over valves, gas masks, residual chlorine testing sets and electrically operated valves.
