The AUTO-PURGER Plus is a totally automatic, electronically controlled refrigerant noncondensible gas (air) and water purger for reducing the energy costs of operating an ammonia refrigeration system. All models are preassembled, pre-wired, insulated, and include an automatic water bubbler, a relief valve, and an isolation service valve package. Installation requires piping the foul gas line, low-pressure pumped-liquid line, low-pressure liquid return line, suction line, water bubbler fill and drain lines, relief valve vent line, water purge line to a customer supplied container, a power connection, and wiring the remote purge point solenoid valves. Purge point solenoid valves must be purchased separately and must be a minimum of 1/2" (13 mm) port size.

In addition to the APPT08, APPT16, and APPT24, a computerized model—APPTC—is available where a separate plant computer or programmable logic controller (PLC) is used to independently operate the various remote purge point solenoid valves.

The AUTO-PURGER Plus can operate over a wide range of condensing pressures. This is important for refrigeration systems that operate at low condensing pressures during cold ambient conditions.

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. For example, a system with 24 points at 10 minutes per point requires a 240 minute (4 hour) cycle. Each purge point can be purged six times a day. If this is not adequate, a second purger should be used and the purge points divided equally between the two purgers.

In a system with normal noncondensible loads, all models will handle a 750 ton (2600 kW) ammonia plant at suction pressures below atmospheric pressure or a 1500 ton (5300 kW) ammonia plant at positive suction pressures. The amount of noncondensibles in the system is based on many factors including age, maintenance practices, and operating temperature.
