THE LIEBERT PROCESS FLUID CHILLER In addition, the Process Fluid Chiller is easy to install, requiring only final piping and wiring connections for proper operation. 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.
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.
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.
