Evaporation control system for reverse osmosis systems. Includes a stainless steel solenoid valve with 1/4 inch John Guest speed fit connections, vertical mount electric float switch, 1/4 inch John Guest shut-off valve and tee fitting.

Plastic float valve for controlling water levels in a reservoir.  Body is ABS plastic with food grade neoprene gaskets and seals. It contains no metal parts. Mounting requires drilling a 5/8" hole about 1" above the desired water level. Mounts like a bulkhead through this hole. It has 1/4" male NPT threads and comes fitted with an adapter compression fitting for 1/4" tubing connection. Adjustment for water level can be made on the side of the float valve over a range of about + or - 1 inch.  This valve can handle pressures up to 90 psi.

SpectraPure’s liquid level controller (LLC) uses the most advanced means of controlling liquid levels on single or multiple reservoirs and is ideal for replenishing evaporated water in aquariums, or liquids in other constant level containers. An on-board air pressure activated electrical switch opens a solenoid valve when the liquid level drops approximately 1" and closes it when the liquid level rises back to its original level. Research at SpectraPure shows that the liquid level controller provides a significant advantage over conventional float and back-pressure activated automatic shut-off valves by maximizing the duration of membrane operation. This minimizes the build up of impurities due to membrane creep (the small amount of impure water that is a characteristic of the membrane at the onset of pure water production). All wetted components are constructed of inert and salt-water safe materials. Power is provided by a plug-in 24 volt AC (UL listed and CSA approved) transformer. The single reservoir model comes with the LLC unit (which includes a switched 24 VAC outlet for controlling a booster pump or other 24 VAC operated devices), compression fittings and 10 feet of tubing for remote mounting of the sensor.
