Purgers, Air & Water - Air Removal Purgers

NEAP, APM & AP Series

NEAP Single Point Non Electric Air Purger


The Non-Electrical AUTO-PURGER (NEAP) is a simplified version of the popular Hansen AUTO-PURGER s. It is designed to remove non-condensible gases, mostly air, from an ammonia refrigeration system, resulting in lower energy costs for the system. The NEAP features welded-pipe, all steel construction and comes preassembled and tested, unlike the Armstrong purger which is shipped as unassembled components and pipes. The simple, heavy-duty design makes the NEAP especially suited for industrial refrigeration systems and does not require sophisticated training for the operators. An optional valve package is available that is easily installed and includes the necessary shut-off valves and gauge valves for the foul gas, suction, and liquid lines.

APM 4 Point Auto-Purger



The AUTO-PURGER M is a compact and totally automatic, electronically-controlled, noncondensible gas refrigerant purger for reducing condensing pressure, and thereby saving electrical energy used by the refrigeration system. This deluxe purger is preassembled, prewired, tested, insulated, and includes an automatic water bubbler. Installation requires piping the "foul gas" line, liquid line, suction line, water line, drain line, and wiring the power connection and the remote ½" (13 mm) port purge point solenoid valves, which must be purchased separately. Up to four (4) purge points can be controlled by this purger. The AUTO-PURGER® M(APM) features welded piping and watertight electrical construction. The APM meets the requirements of the Canadian Standards Association (CSA certified).

AP Series Single and Multi Point Purgers


This is the original AUTO-PURGER. It has solid-state control and is ideal for larger systems, up to 1500 tons (5300 kW) ammonia. This is two to three times the air removal capacity of the Armstrong purger. With models available to purge up to 24 points, the AP features automatic start-up with electronic control. The purge cycles 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. For ammonia and halocarbon refrigeration systems. Assembled, tested, and ready to run.
