Overview
The AUTO-PURGER is a unique energy-saving device designed to lower operating condensing pressure, increase refrigeration capacity, save electrical power, and reduce emissions of refrigerant to atmosphere.
AP Plus
The AUTO-PURGER PLUS is a totally automatic, electronically controlled non-condensible gas (air) and water purger for reducing the energy costs of operating an ammonia refrigeration system. The AUTO-PURGER PLUS is shipped preassembled, prewired, insulated, and includes an automatic water bubbler, a relief valve, and an isolation service valve package. All AUTO-PURGER’s are factory tested.
AP Auto-Purger
This is the original AUTO-PURGER. It has solid-state control and is ideal for larger systems, up to 1500 tons (5275 kW). The AP has at least two to three times the air removal capacity of any competitive purger, and up to ten times other smaller purgers. With models available to purge up to 8, 16, and 24 points, the AP features automatic startup with electronic control. The purge points can be individually adjusted to meet system requirements. The AP includes an automatic water bubbler. An optional NEMA 4 rated enclosure is available. A European option is available that features all-welded construction and conformance to European electrical standards. The AP is CSA certified. Models are available for use with ammonia or halocarbon refrigeration systems.
APM Auto-Purger
A more compact version of the original AP, the AUTO-PURGER APM is ideal for medium size systems, up to 200 tons (703kW). Like the AP, the APM features automatic start-up with electronic control. Designed for up to four purge points, an electronic "brain" searches for noncondensible gases in the system and purges at those points where air is present. The APM includes an automatic water bubbler and comes standard with a NEMA 12, 13 control cabinet. For use with ammonia or halocarbon refrigeration systems. CE and CSA certified.
Mini Auto-Purger
The nonelectric Mini AUTO-PURGER is ideal for smaller systems up to 100 tons (350 kW) ammonia. The simple design of the Mini AUTO-PURGER features fully automatic startup, like the other AUTO-PURGERs, and is generally used to purge a single point. For use with ammonia refrigeration systems.
