CryoDax X Mydax CryoDax X ultra low-temperature process cooling chiller
Pushing the limits of cooling

Extreme cold, without compromise.

CryoDax X extends the proven CryoDax platform into ultra-low territory — reaching −85°C with the precision, reliability, and build quality of every Mydax chiller.

Ultra-low reach

Down to −85°C for the most demanding cold-process and test applications.

Patented proportional control

0–100% proportional cooling & heating for unmatched precision and efficiency.

Sealed for ultra-low

A sealed stainless reservoir is standard on CryoDax X, with seal-less pumps and a rugged frame.

The CryoDax family

Pick the range your process needs.

Every CryoDax shares the same precision platform — CryoDax X pushes it furthest into the cold.
