Automatic. Insulated. Dependable.

AP Auto-Purger

The original AUTO-PURGER, the AP Auto-Purger 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. Purge points can be individually adjusted to meet system requirements. Includes an automatic water bubbler; Optional NEMA 4 rated enclosure also available.

A European model 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.

The number of purgers required for a system depends on the number of installed purge points. Twenty-four purge points is the maximum practical number per purger.

Mounting Instructions

Mount the AUTO -PURGER securely on a wall or sturdy steel channels capable of supporting 450 lbs (205 Kg). Eight mounting holes in the frame are provided to support the unit. The unit should be located in an accessible area, but away from moving equipment that could accidentally come in contact with the purger. Elevation with respect to condensers or high-pressure receivers is not critical. Do not punch access holes in the top of the control cabinet. Unused electrical entrances to the enclosure must be sealed to protect the controls from moisture.

The AUTO – PURGER is normally installed in the compressor room where it can be monitored, but also may be installed outdoors where temperatures below freezing are not anticipated. For outdoor use, areas near falling or spraying water, or in constant high humidity areas, an optional NEMA 4 enclosure with sealed conduit wiring is recommended.

NOTE:

The freon purgers have a spacer with a set screw which is tightened on the neck assembly. If the float switch assembly is not properly positioned and retained, the switch may not function.
