k ARA VersaTemp units provide all the benefits of a Dedicated Heat Recovery Chiller™ (DHRC) including: •Full cooling capacity with zero need for hot water •Full simultaneous heating and cooling capacity •Full heating capacity with zero need for chilled water • High effective COP ensures reduced operating expense • Fast payback • Reduced carbon footprint • Can be easily combined with select  ASP air-cooled modular chillers (See Pg. 11) plus pump, free cooling and accessory modules Innovative Design for Maximum Flexibility • Integrated source-sink/refrigerant-to-air heat exchanger—no need for a well field or backup heat sinks • Four-pipe operation with brazed plate condenser sized for full heat rejection—NOT A DESUPERHEATER • Provides four to six times more heat than a desuperheater • Built-in automatic controls for full, partial (with multiple modules), or no hot water production; surplus heat is rejected via the integral air-cooled heat exchanger Leverages the Advantages of a Modular Design • Redundant systems up to 600 tons capacity • EC fan motors (575 volt units require optional transformer) paired with low-sound fan blade technology for quiet operation • Optional chilled water and/or hot water pumping packages • Optional tanks, air separators, and accessories • Integrated controls with multiple connectivity options ARA VersaTemp units use scroll compressors and are available as 20-, 30- or 60-ton modules which may be assembled into an array to provide the required jobsite capacity and redundancy. Each module includes two compressors, common single-circuit evaporator, single-circuit refrigerant-to-hot water heat exchanger, single-circuit air-to-refrigerant heat exchanger, electronic expansion valves, reversing valve, and control system. Modules are shipped wired and charged with refrigerant and are factory run-tested prior to shipment on an AHRI certified test stand. ARA modules are ETL listed according to UL Standard 1995, and CSA certified per Standard C22.2#236. Compressors Each module includes two hermetic scroll compressors in a tandem piping arrangement mounted to the module with rubber-in-shear isolators. Each system also includes high discharge pressure and low suction pressure safety cut-outs. Refer to unit nameplate for specific refrigerant charge. Hot and Chilled Water Heat Exchangers The evaporator is a brazed plate heat exchanger constructed of 316 stainless steel; designed, tested, and stamped according to UL 1995 code for 650 psig working pressure. The condenser is a brazed-plate heat exchanger also constructed of 316 stainless steel and designed, tested, and stamped in accordance with UL 1995 code for 650 psig working pressure. Refrigerant to Air Heat Exchanger Each module contains dual (four in ARA 060X) variable speed axial fans. Fan blades are of aluminum construction using ultra-quiet owlet design. Each fan has seven blades and an integral EC motor (575 V units require optional transformer). Control System VersaTemp module operation is controlled by a microprocessor master controller that monitors entering and leaving chilled water and hot water temperatures to determine both the chilled water and hot water system demand. The control system uses demand to make staging mode decisions (cooling, heating, or simultaneous heat recovery) and select the needed number of compressors. Mode decisions are available from the controller as well as via remote input. Response times and set points are adjustable. The master controller provides for variable time between compressor sequencing and temperature sensing in order to optimize chiller performance and efficiency at varying building loads.
