A rack-mounted recirculating chiller offers even more temperature stability due to its use of thermoelectric, or Peltier, cooling. The chillers are made to fit easily in standard 19” rack systems, but optional mounting feet can be purchased for benchtop applications. The rack-mounted chiller’s air-cooled Peltier cooling is offered in a self-contained package with fan cooled heat exchanger, pump, reservoir tank and power supply all included.
