     The DMC-14-G2  and DMC-20-G2 rack mount chillers from K-O Concepts, Inc. can cool heat loads up to 1,400 and 2,000 watts (respectively).  These industrial process water chillers have been designed for laser, laboratory, medical, and manufacturing cooling. The DMC-14/20-G2 has advanced temperature control that is able to maintain within ±0.1°C of set point. Waste heat is harvested from the system’s compressor to quickly raise the temperature of the process water up to approximately 50°C without an external heat load (~40% of the BTU rating of the chiller unit is available for heating).  K-O chillers are power miserly and use about 33-50% of the power of competing chillers.  The volume of a DMC-14/20-G2 is 12-65% less than competing models, and weighs between 76-85 lbs. (35-39 kg). 

     All models of recirculating coolant chillers from K-O Concepts have several key features in common.  Our standard 19 inch, rack-mounted configuration allows our cooling modules to be easily integrated into any system.  Available for all models are optional free-standing conversions (for those needing a portable unit with wheels).  All module cabinets are equipped with handles for ease of installation and are air-cooled.  We use R134a (HFC-134a) refrigerant in our chillers, chillers using this refrigerant can be sold in Europe and Asia (not affected by Montreal Protocol).  Several communications options are available upon request depending on the needs of your application (RS-485, RS-232, Modbus RTU or TCP, USB 2.0, Digital I/O). In addition to all our innovative features our chillers are designed rugged and for easy maintenance. 

     Below is an abbreviated list of specifications and a few showcased optional features. Please view our DMC-14/20-G2 brochure at the bottom of the page for a full detailed spec sheet and associated performance graphs.  There are also more optional accessories and replacement parts available, please download the accessories and parts brochure for details.
