What sets Mydax apart
Industry first · Since 1986
Patented proportional refrigeration — engineered for precision.
Mydax was the first chiller manufacturer to offer proportional refrigeration control — the technology behind the temperature stability that delicate semiconductor processes depend on.
The problem with conventional chillers
Most wear and breakdowns in chiller operation are caused by On/Off temperature cycling of the refrigeration circuit’s plumbing and components — the cycling that shortens service life and risks process-critical temperature drift.
The Mydax solution
Our proportional design smoothly adjusts refrigerant flow along the compressor’s power curve based on the cooling required, diverting excess capacity to a bypass heat exchanger. The result: tighter temperature stability, less thermal stress, and consistent process yields.
