Remote Air Cooled Chillers

Air cooled remote chillers are are used when the air inside a plant is either corrosive, extremely dusty, hot, where supplemental heating is of no benefit, or where the plant is air conditioned.

Remote air cooled industrial process chillers consist of an inside chiller unit and an air cooled condenser for remote mounting. Berg’s rugged industrial process chillers are manufactured and factory tested under load conditions to ensure they stand the test of time.

Our custom engineered industrial chilling solutions for your unique application are developed for quiet operation, high efficiency and maximum return on investment. At Berg Chilling Systems Inc, we are proud of our air cooled industrial refrigeration units, and our engineering and design difference.

Safety Controls

All Berg industrial chillers are tested under load conditions prior to shipment. All safety controls are factory set and checked

  • Freeze-up controls
  • High and low refrigerant pressure controls
  • Compressor motor overload protection
  • Oil pressure safety control
  • Refrigerant pressure relief valve

Electrical

  • 460 / 575 / 230 / 380 Volts       60 / 50 Hz
  • 120 / 240 Volt single phase control voltage
  • Microprocessor controller
  • Operating and fail lights
  • UL or CSA approved components

Central Control Electrical Panel

A custom electrical control panel allows one point hookup and may include:

  • HMI (Human Interface Device) touchscreens
  • PLC (Programable Logic Control)
  • SCADA (Supervisory Control And Data Acquisition) communication systems
  • 24/7 alarm reporting to beepers or cell phones

All pump starters, fuses, disconnect, control voltage transformer, run and fail lights, are housed in a common NEMA rated panel.

Optional Stainless Steel Tank & Centrifugal Pump Assembly

Stainless Steel Tank

  • Baffled Stainless Steel type 304 Reservoir, 11 gauge
  • Reinforcement bands
  • Removable stainless steel cover
  • Overflow connection
  • Bottom drain connection with shut‑off valve
  • Automatic float operated water make‑up valve
  • Thermometer with well
  • Spare well opening
  • Closed cell flexible insulation nominal ½” thick applied to bottom and sides of tank

Centrifugal Pump Assembly

*Evaporator pumps circulate water from the hot well to the chiller and back to the cold well.  This provides a constant flow and pressure for stable operation, maximum efficiency and safety.

*Process pumps circulate water from the cold well to the process and back to hot well.  This flow may fluctuate without affecting the flow through the chiller.

*Optional combined standby pump, complete with valved header assembly is capable of acting as either the chiller or process pump if necessary to prevent any unnecessary shut-downs due to an operating pump fault.

Pump assembly includes:

  • Close coupled TEFC motor
  • non-overloading impeller
  • Cast iron volute
  • Brass shaft sleeve
  • Mechanical seal
  • Suction shut‑off valve
  • Discharge flow/shut‑off valve
  • Discharge check valve
  • Discharge pressure gauge
