Water cooled electronic equipment has special needs beyond cool water. Sensitive equipment requires year-round operation, precise temperature-regulated water flow and a clean circulating loop—features only available with an equipmentmatched, dedicated chiller. For best reliability, this chiller should be factory-tested and supported. Built-in quality, along with Liebert’s leadership role in supporting critical electronic systems, make the Process Fluid Chiller the logical choice to support your water-cooled equipment. The Process Fluid Chiller is available in capacities to accommodate a variety of sensitive equipment: Liebert Process Fluid Chillers are matched to the application to provide the proper temperature and flow rate for a variety of sensitive electronic systems.

Tank R = Gauge/Heater/ Multistage Pump (8/10 ton models) 1 Standard Features Frame and Panels Refrigerant Dehydrator The unit base is heavy-gauge galvanized steel. The exterior panels are painted and provide a durable, weather-resistant finish. The refrigerant dehydrator assures a moisture-free refrigerant system for extended component life. Indoor or Outdoor Installation The weatherproof panels and rugged components are durable for placement outdoors. Circulating fluid may be specified with propylene or ethylene glycol to adapt the unit to cold climates. Compressor The compressor is a fully hermetic, reciprocating design with overload protection. It has rubber isolated mounting to reduce noise and vibration. A liquid line sight glass/moisture indicator is included as well as a manual reset high-pressure switch. The high-efficiency scroll compressors are standard on 4-ton, 8-ton, and 10-ton models. Expansion Valve The externally equalized thermostatic expansion valve smoothly controls refrigerant flow and provides precise control of superheat. Refrigerant Receiver The refrigerant receiver provides a liquid seal and storage of refrigerant when the system is operating in ambients from minus 30°F to plus 115°F (-34°C to +46°C). Performance will be reduced above 95°F ambient. Consult factory for derated capacities. Stainless Steel Pump To provide a non-ferrous circulating loop to protect sensitive electronics, a pump with a stainless steel housing and impeller is part of the design. Fluid Pressure Relief Valve The 3/4" (2 cm) FPT brass, high pressure relief valve is mounted on the inlet pipe to the fluid reservoir expansion tank for safety protection against system pressures over 50 psi (345 kPa). Fluid Reservoir Expansion Tank The fluid reservoir expansion tank is manufactured of 14 gauge stainless steel, and provides thermal storage to act as a buffer for rapid load changes and to provide an area for fluid expansion. Expansion volume is one gallon (3.8 liters); maximum working pressure is 50 psi (345 kPa). Refrigerant Pressure Relief Valve A relief valve mounted on the receiver protects the refrigerant circuit from high pressure situations. Control System This module contains controls for fluid temperature, refrigerant low pressure switch, manual reset high pressure switch, low ambient start relay, compressor anti-recycle relay, transformer with circuit breaker and remote shutdown. Factory-Installed Options Refrigerant Gauges Tank Heater Fluid Thermal Storage Tank For at-a-glance monitoring, suction and discharge refrigerant gauges with large dial faces are conveniently mounted on the unit exterior. These gauges are stainless steel for durability. (Sold only with tank heater). An optional copper sheath/stainless steel insertion heater maintains minimum fluid temperature during low ambient conditions. (Sold only with refrigerant gauges). The insulated, stainless steel tank is built into a frame with panels, and is factory mounted and piped below the chiller cabinet. The tank is 50 gallons (190 liters) on 3-5 ton models, and 100 gallons (380 liters) on 8 and 10-ton models. Multistage Pump (8 and 10-ton models) This optional pump provides up to 200 ft (597 kPa) of head pressure at 15 gpm (57 lpm). See Figure 9 - Process chiller pump performance—60Hz. 2 See drawings in “Dimensional Data” on page -6. Optional System Accessories (Field-Installed) Fluid Pressure Gauge Isolation Ball Valve A 2 ½ inch (6.35 cm) analog gauge for monitoring supply or return pressure is available. The readout is dual scale: 0 to 100 PSI and 0 to 7 BAR. An available brass, ¼ turn isolation valve provides for isolation of fluid piping components in the event of a service necessity. Dial Thermometer To provide supply or return fluid temperature measurement, a hermetically sealed dial thermometer is available. The externally adjustable, 2 ½ inch (6.35 cm) dial is scaled from 20 to 130°F (-6.7 to 54.4°C). Check Valve A brass, swing check valve is offered for installation in the chiller outlet piping to prevent backflow through the chiller. Circuit Setter This is a calibrated balancing valve that, when installed in the chiller outlet piping, provides for flow balance, flow metering and shut off of fluid flow. Water Level Control and Alarm System This module automatically adds water to the thermal storage reservoir when the water level drops below a preset level. It consists of an on/off switch, a 24 VAC control transformer protected by a circuit breaker, a flow regulating solenoid valve, a double check backflow preventer and time delay relays. The module also includes a prewired RCM4 monitor with local display and non-powered common alarm contracts. ! High Temperature Thermostat A remote bulb, adjustable (4090°F, 4.4-32°C) thermostat provides alarm contact when the fluid temperature rises above a design limit of system operation. (See Monitoring and Alarms section for RCM8 Monitoring System). Low Flow Switch A flow switch provides set point and alarm contact when fluid flow falls below a design limit of system operation. (See Monitoring and Alarms section for RCM8 Monitoring System.) Wall-Mounted Monitoring Box This unit includes supply and return ball valves (six total), a flowmeter, a water filter with bypass, pressure gauges (supply and return), temperature gauges (supply and return) and 3/4" barbed connections. Emergency Water Switchover Module (for systems circulating water) On a high fluid temperature alarm or loss of fluid flow alarm, this unit will automatically switch to emergency water. This redundant cooling source protects your critical equipment from potentially damaging high temperatures or unplanned shutdown. See WARNING below. RCM4 Four-Point Dry Contact Monitor is a four-point, normally open, dry contact monitoring panel. One Form C, dry contact common alarm relay output (rated at 24 VAC, 3 amp) is provided. The RCM4 requires 24 VAC or 24 VDC power source. Power supply is not included. Four red LEDs illuminate on alarm and the alarm buzzer is silenced by a front panel switch. RCM8DO Eight-Point Dry Contact Monitor is an eightpoint, dry contact input and eight dry contact output monitoring panel. It is identical to the RCM8CE, but with the addition of eight normally open relays (rated at 24 VAC or VDC, 1 amp) that will automatically energize upon alarm of each corresponding monitoring point. RCM8CE Eight-Point Dry Contact Monitor is an eightpoint, normally open or normally closed (individually selectable) dry contact monitoring panel that can be used: • as a stand-alone panel. • to dial out on alarm to a remote location or numeric/ alphanumeric pager. • to interface with Liebert SiteScan centralized monitoring systems. WARNING The emergency water source module is for use on systems that circulate water as the cooling medium. Using this option on a glycol system will dilute the glycol solution during emergency operation and could damage the environment as well as violate regulations for disposing of glycol solutions. 3 Technical Data Table 2 Air-cooled data—60Hz PS018A PS024A PS036A PS048A PS060A PS096A PS120A 1.5 Tons 2 Tons 3 Tons 4 Tons 5 Tons 8 Tons 10 Tons Circulating Fluid—Water Coolant Flow Rate - GPM (L/M) 2.4 (9) 3.3 (12.6) 5.9 (40.7) 11.1 (76.8) Pressure Drop - PSI (kPa) Net Cooling Capacity—BTUH (kW) 5.3 (19.8) 7.9 (29.4) 10.2 (38.4) 16 (60.6) 20 (75.8) 5.1 (35.0) 8.1 (55.6) 13.3 (91.8) 8.1 (55.8) 13.2 (91.0) 45°F (7.2°C) LWT 11800 (3.5) 17000 (5.0) 26600 (7.8) 39300(11.5) 51200 (15.0) 77200 (22.6) 91600 (26.8) 50°F (10°C) LWT 13300 (3.9) 19400 (5.7) 29500 (8.6) 42500 (12.4) 57400(16.8) 83600 (24.5) 102400 (30.0) 55°F (12.8°C) LWT 14800 (4.3) 21700 (6.4) 32600 (9.5) 45900 (13.4) 63500 (18.6) 90400 (26.5) 113000 (33.1) 60°F (15.6°C) LWT 16000 (4.7) 23900 (7.0) 35900 (10.5) 49700 (14.6) 69200 (20.3) 97600 (28.6) 122600 (35.9) Std.
