The Series FX5500 floor-mounted chlorinators are vacuum operated, solution feed devices available with either manual or automatic control. Each chlorinator system is composed of three parts; a vacuum regulator, a control module, and an ejector. The color impregnated cabinet, which encloses the control module, is constructed of fiberglass-reinforced polyester, molded high impact polystyrene and pressure formed thermoplastic with a textured easily maintained finish.
Chlorinator feed rates are dependent on the maximum withdrawal rates from the gas source. The flowmeter, mounted in the control module is available in a wide selection of capacities. Maximum chlorinator capacities range from 1,000 to 10,000 lb/day (20 to 200 kg/h).
When automatic control is required, the Chloromatic® valve, mounted within the control module, responds to control signals from a water flow transmitter and/or a chlorine residual analyzer controller. An integrally mounted controller can be provided to receive the process flow and analyzer signals and control the valve position.
The ejector has a fixed diameter nozzle and throat, the size of which depends on the maximum chlorine feed rate and the hydraulic conditions existing in the water supply and chlorine solution lines.
Several control modules may be used together to construct a system for the multipoint application of chlorine. The gas flow from the vacuum regulator may be divided to feed more than one application point with the flow to that point being either manually or automatically controlled. The sum of the flows to all application points cannot exceed 10,000 lb/day (200 kg/h).
Units similar to those feeding chlorine (but with different materials of construction) are available for feeding sulfur dioxide, ammonia and carbon dioxide gases. The maximum capacity of the feeders are 10,000 lb/day per sulfur dioxide, 4800 lb/day for ammonia, and 6200 lb/day for carbon dioxide.
