Recirculating Heat Exchangers
Recirculating Heat Exchangers
Liquid-to-liquid cooling, no refrigeration required.
Mydax liquid-to-liquid heat exchangers provide efficient closed-loop circulation wherever facilities water is available and at least 5°C colder than your target fluid — with superior temperature stability for demanding industrial use.

Liquid-to-liquid cooling
Efficient cooling, when you have the water.
When facilities water is available and cold enough, a heat exchanger skips the compressor entirely — delivering precise, stable temperature control in an efficient, economical closed loop.
Efficient by design
Closed-loop recirculation using your facility water — no refrigeration compressor needed.
Superior stability
Advanced PID control and Opdax HMI hold temperatures to ±0.5°C or better.
Heating & cooling
One system does both, with a smaller footprint and economical operation.
Built around your facility
Configured for your process.
Multi-Loop Systems
1, 2, or 3 independent channels for multiple process temperatures in a single, space-saving unit.
Specialty-Fluid Compatible
Deionized water, Water/Glycol, PAO (Royco 602 / MIL-PRF-87252), Galden & H-Galden, Fluorinert & Novec.
Facility-Water Sweet Spot
Ideal when facilities water is available and at least 5°C colder than your desired heat transfer fluid.
