What are PAO chillers?
A synthetic hydrocarbon fluid, engineered for sensitive cooling.
PAO (Polyalphaolefin) is a synthetic hydrocarbon fluid with exceptional properties that make it ideal for sensitive cooling applications. Mydax PAO chillers are designed to optimize these benefits across the most demanding industries.
Wide thermal stability
Performs reliably from −40°C to +80°C across changing loads.
Non-conductive
Ensures safe operation in and around electronic and military systems.
Low-viscosity
Maintains efficient flow and heat transfer for stable performance.
Built for the most demanding missions
Defense & aerospace, cooled with precision.
Where electronics can’t get wet and failure isn’t an option, non-conductive PAO cooling protects the systems that matter most.
Military & Defense
Cooling radar, communication, and weapons systems in the field — where non-conductive PAO safeguards mission-critical electronics under extreme conditions.
- Rugged, leak-free construction
- Outdoor-rated & multi-loop options
Aerospace
Thermal regulation for avionics and electronics, with low-viscosity PAO that performs reliably from −40°C to +80°C across demanding flight and test environments.
- Precise ±0.5°C stability
- Compact, custom-engineered builds
