Automatic. Insulated. Dependable.
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. Models are available to purge up to 8, 16, and 24 points. Includes an automatic water bubbler and comes standard with a NEMA 4-rated enclosure.
The APWT is CSA certified. Models are available for use with ammonia systems only.
The number of purgers required for a system depends on the number of installed purge points. Twenty-four purge points are the maximum practical number per purger.
The APWT has the same install footprint as the APW (and AP). 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 in an accessible area, but away from moving equipment that could accidentally encounter 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. The APWT comes standard with a NEMA 4 enclosure for outdoor use, areas near falling or spraying water, or in constant high-humidity areas. Sealed conduit wiring is recommended.
