Mydax CryoDax Series
Very Low Temperature Liquid Chiller / Heater Systems

With over three decades of experience and refinement of low temperature liquid chiller / heater systems, Mydax has designed the CryoDax series of chillers to provide Quality, Reliability and Performance for demanding industrial temperature control applications.

With a temperature range of -70°C to +80°C standard (-70°C to +150°C available) and large cooling capacities at low temperatures, CryoDax chiller systems offer industrial temperature control solutions for Hydrogen Fueling, Semiconductor, Pharmaceutical, Automotive, Aerospace, Medical, Extraction and Custom applications.

CryoDax Low Temperature Chiller systems are an excellent choice for Extraction Chiller Applications that require high cooling capacity at low temperatures.

Our CryoDax H2 systems are designed specifically for Hydrogen refueling precooler applications.

Like all Mydax chiller systems, our CryoDax low temperature liquid chiller systems utilize our Advanced Temperature Control Technology 0 to 100% proportional cooling and heating control, rugged tubular steel frames and touchscreen controls along with leak free pumps, process fluid flowmeters, stainless steel brazed plate heat exchangers and all brazed copper piping. Each system undergoes rigorous quality assurance testing with system documentation and performance graphs provided.

CryoDax systems include UL-508A Industrial Control panels and are ETL listed.
