A.I. TEC manufactures extra-powerful refrigeration units that can attain temperatures as low as -65°C without the use of liquid nitrogen.
Units run much more efficiently and safely compared to conventional liquid nitrogen coolers.
They can be run continuously for long periods of time, can be easily adapted to installation plans and changes in production line layout,and can be used at room or high temperature conditions.
A wide range of temperatures can be obtained with a single unit.
Refrigeration units are mainly used in low- and high-temperature automobile electronic component testing lines and medical equipment manufacturing lines.
Feature
Wide range of temperature control
Units can attain temperatures of -65°C to -125°C.
Precise temperature control
Maintains desired temperatures within tolerances of ±0.1°C.
Low running cost
Maintains extremely low temperatures in testing units by circulating cold air instead of liquid nitrogen.
Efficient refrigeration system
Uses a two-step refrigeration process to circulate extremely cold air very efficiently in a small space.
Diverse line-up
Both air-cooled (AI-860) and water-cooled (AI-830) models are available.
The water-cooled AI-870 model is a recent addition to our product line with greatly increased cooling power in a small unit.
Extended continuous operation
Units can run continuously for periods of up to 168 hours.
Flexible layout planning
Layout planning and changes are simpler than for systems requiring liquid nitrogen.
Easily controllable
Units can be monitored and adjusted easily by matching control devices developed by A.I. TEC.
Safe
There is no longer a risk of injury or oxygen shortage from a nitrogen leak.
Environmentally friendly
Units use a refrigerant that does not harm the ozone layer.
