Simple operation and advanced monitoring from a new control

The EP2 Series Portable Chillers feature a 7-inch full color touchscreen HMI, with a slopped-stop enclosure, making viewing and operation quick and easy. Advanced monitoring, such as pump and compressor running hours, trending charts, and a digital pump pressure display, provide a wide range of useful information.

Ready for severe-duty industrial cooling

The EP2 models are designed to meet severe-duty industrial cooling needs and provide additional resistance to harsh fluid conditions and operating environments. All EP2 chillers feature stainless steel pumps, stainless steel evaporators, and a process fluid circuit with corrosion-resistant materials to prevent rust and ensure clean, dependable operation for many years.

Energy savings every day

From the standard high-efficiency scroll compressors, premium microchannel air-cooled condensers, and compact stainless steel evaporators to premium-efficiency EC condenser fan and variable-speed compressor options, Conair’s EP2 Series Chillers offer the best available energy-savings through new technology and available options.


Control Features:

  • Compressor Protection Technology: Our compressor protection technology uses start-to-start anti-recycle control logic to limit cycling under low-load operating conditions to extend compressor life.
  • Compressor and Pump Run Hour Displays: The ability to monitor compressor and pump running hours is an important tool to assist with scheduling maintenance.
  • Power Monitor: The main power monitoring system protects the chiller from extensive damage to the compressor and pump due to loss of phase or phase reversal in the main supply.
  • Reservoir Low Level Alarm: Indicates a low process fluid condition and protects the process pump and chiller from expensive damage caused by a critically low operating level in the reservoir.
  • Temperature Warnings and Alarms: A warning alerts the operator of a potential problem before a fault occurs and if the condition gets worse, an alarm stops the chiller to prevent damage.
  • Adjustable Alarm Time Delays: Allows for programing a start-up alarm time delay to deactivate the alarms long enough for the process loop to stabilize before activating the alarms.
  • High-Quality 24 VDC Power Supply: The 24-volt DC power supply ensures dependable control circuit power and isolates the control circuit from static interference to ensure stable and precise operation.
  • Trending Charts: All control systems include the ability to chart key operating parameters, such as process fluid supply and return temperatures, for a quick display of operating trends.
Mechanical Features:
  • Stepper motor driven hot gas bypass
