What sets Mydax apart
Industry first · Since 1986
Patented proportional refrigeration — engineered for defense.
Mydax was the first chiller manufacturer to offer proportional refrigeration control — the technology that delivers the stability and longevity mission-critical defense equipment depends 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 instability in sensitive equipment.
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 equipment that lasts in the field.
