Introduction
General Description
McQuay AGS-DP air-cooled water chillers are complete, self-contained, automatic
refrigerating units that include the latest in engineered components, arranged to provide a
compact and highly efficient unit. Each unit is completely assembled, factory wired,
evacuated, charged, tested and comes complete and ready for installation. Each unit consists
of multiple air-cooled condenser sections with an integral subcooler section. Each condenser
circuit has a semi-hermetic single-screw compressor, solid-state starter, a multiple-circuit shelland-tube flooded evaporator, and complete refrigerant piping. Each compressor has an
independent refrigeration circuit. Liquid line components included are manual liquid line
shutoff valves, charging ports, filter-driers, sight-glass/moisture indicators, and electronic
expansion valves. A discharge check valve is included and a compressor suction shutoff valve
is optional. Other features include compressor heaters, evaporator head heaters, automatic
one-time pumpdown of refrigerant circuit upon circuit shutdown, and an advanced fully
integrated microprocessor control system.
Information on the operation of the unit and on the MicroTech II controller are in the OM
AGS-DP manual. Installation and operating instructions will be shipped with the unit if a
LONTALK, Modbus or BACnet BAS interface is ordered.
