SpectraPure® Single Tank Liquid Replenishers are the most advanced means of controlling liquid levels on single reservoirs, and are ideal for replenishing evaporate water in aquariums or liquids in other constant level containers. An onboard 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 Single Tank Liquid Replenisher 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 saltwater 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 controller, which includes a switched 24 volts AC outlet for controlling a booster pump or other 24 volt AC operated devices, compression fittings, and 5 feet of tubing for remote mounting of the sensor.
