Find the right chiller for your temperature.
“Low temperature” means something different to every industry — a hydrogen station thinks −40°C, a biotech freezer thinks −80°C, a supermarket thinks −20°C. Tell us your requirements and setpoint, and we’ll match you to the right Mydax system in a few questions.

How Mydax works
One platform. Three ways to configure.
Whether you need a standard system, a standard system with specific upgrades, or a fully custom-engineered build — Mydax has a path for your application and timeline.
Standard systems
Proven configurations, ready to order
Catalog-proven chiller systems covering the most common temperature ranges, cooling capacities, and form factors. Faster lead times, known specs, reliable performance.
Examples:
- CryoDax low-temp chiller series
- Air-cooled process chillers
- Water-cooled industrial systems
- Recirculating heat exchangers
Most Popular
Standard + Add-On Options
Start standard, configure to your application
Choose a standard base system and add the options your application requires. Gets you a configured solution without full custom lead times or cost.
Popular add-on options include:
- Heating capability (up to 3kW standard)
- PAO / MIL-spec fluid compatibility
- Outdoor weatherproof enclosure
- Particulate or deionizing filtration
- Communications integration (Modbus, RS-232)
Full Custom Engineering
Unique requirement? We engineer from scratch.
For applications that no standard or configured system can meet. Our engineers design, build, and test a system to your exact specification — temperature range, form factor, fluid compatibility, communications, and more.
Common custom applications:
- OEM integration — custom form factors
- Multi-loop configurations (2, 3+ circuits)
- Defense program specifications
- Non-standard temperature ranges
What sets us apart
Industry first · Since 1986
Patented proportional refrigeration control.
Mydax was the first chiller manufacturer to offer proportional refrigeration control — and it’s still the heart of what makes a Mydax chiller last.
The problem with conventional chillers
Most of the wear and breakdowns associated with chiller operation are caused by On/Off temperature cycling of the refrigeration circuit’s plumbing and components. This cycling — long associated with conventional chillers — is what shortens their service life.
The Mydax solution
Our proportional design smoothly adjusts refrigerant flow along the compressor’s power curve, based on the cooling required. Excess capacity is diverted to a bypass heat exchanger — easing thermal stress and eliminating the cycling wear that limits conventional chillers.
Eliminates cycling wear
Longer service life
Tighter stability
Less thermal stress
CryoDax · CryoDax X
Precision cooling, down to −85°C.
One precision platform, two ranges. CryoDax is the standard low-temperature workhorse, holding −70°C to +80°C for precise, repeatable sub-zero process cooling. CryoDax X pushes the same platform to −85°C — with cooling capacity up to 40 kW and multi-loop configurations for the most demanding scientific and industrial work.
