Ultra Low Temp Chillers
Our Ultra-Low Temperature Series Chillers deliver temperatures as low as -90°C and are available in both air-cooled and water-cooled configurations. Designed for maximum efficiency, these units include a updgraded, heavy insulation package. We manufacture ultra low temperature chillers that are compatible with a range of heat transfer fluids to meet the demands of extreme cooling applications.
Available In All Capacities

Frequently Asked Questions About Our Ultra Low Temp Chillers
Q: How cold can the Ultra Low Temp chillers go?
The ULT Series reaches process temperatures as low as -90 °C. Achieving these temperatures typically requires single- or multi-stage (cascade) refrigeration matched to your exact setpoint and load.
Q: What heat transfer fluids are compatible?
ULT units run a range of low-temperature heat transfer fluids, such as silicone-based fluids and other secondary coolants rated for the target temperature, rather than water, which would freeze. Provide your setpoint so the correct fluid and materials are specified.
Q: Are ULT chillers air-cooled or water-cooled?
Both configurations are available, so the unit can be matched to your site’s heat-rejection method and ambient conditions. A heavy insulation package is included to maintain efficiency and prevent condensation and frost at ultra-low temperatures.
Q: What applications use ultra-low-temperature chillers?
Common uses include materials and component testing, environmental and thermal chambers, semiconductor and laboratory processes, and solvent or oil extraction requiring deep cooling. Capacities are available to suit; consult the factory for sizing.
Q: How is capacity rated at ultra-low temperatures?
Refrigeration capacity drops significantly as setpoint temperature decreases, so a unit’s tonnage at -40 °C is very different from its capacity at -90 °C. We size ULT units at your actual operating temperature, not at standard rating conditions, so the unit holds setpoint.
