Hansen APM-1, Auto-Purger M, 4 PTS, NH3, 115V 50/60HZ, Noncondensible Gas.

A more compact version of the original Hansen Auto-Purger, the AUTO-PURGER APM is ideal for medium-size systems, up to200 tons (700 kW). Like the Hansen Auto-Purger, 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 when air is present. The Hansen Auto-Purger M includes an automatic water bubbler and comes standard with a NEMA 12,13 control cabinet. For use with ammonia refrigeration systems. Assembled, tested, and ready to run.
