Air-Cooled Chillers
Air-Cooled Chillers
Precise cooling, without a water source.
Mydax air-cooled liquid chillers deliver precise temperature control when a water source isn’t available — using fans to dissipate heat efficiently, with patented proportional refrigeration control for industrial-grade stability.

Air-cooled
Why air-cooled
Efficient cooling, no water required.
Air-cooled systems use fans to dissipate heat, making them ideal for facilities where a condenser water source is limited or unavailable — without compromising precision.
No water source needed
Fans dissipate heat efficiently — ideal where water is unavailable.
Patented proportional control
Advanced refrigeration control for precise, repeatable temperature control.
Flexible & fluid-compatible
Multi-loop builds and a wide range of heat transfer fluids.
Any industry
If it needs precise cooling, we can build it.
Mydax air-cooled chillers are engineered to order — adapting to virtually any industrial, laboratory, or process cooling challenge, with the temperature range, capacity, and heat transfer fluid your application requires.
