If you have assessed all available chillers and still cannot find one that meets the specifications, consider looking into a custom solution. Have the following in mind when discussing custom requirements with a manufacturer:

•           Cooling capacity at specific temperature(s).

•           Temperature range.

•           Integrated heater ― capacity requirements.

•           Control electronics ― basic or advanced with programmability.

•           External temperature control/monitoring ― RTD or thermocouple.

•           Pump requirements ― flow rate, pressure capacity.

•           Air- or water-cooled condenser.

•           Inline filtration.

 •           External communication requirements.
