Direct DC Variable-Capacity Cooling Solutions

Masterflux Applications

Well suited for a variety of DC applications covering the ordinary to the extraordinary:

Idle Mitigation

Masterflux's line of compressors is ideally suited for battery powered no-idle applications for OEM and aftermarket systems.

Battery Thermal Management

Masterflux's compressors and Battery Thermal Management systems are designed for fast and efficient Air and Liquid Cooling of EV Battery Packs.

Last-Mile Delivery

Quiet, robust and highly-efficient cooling designed for frequent deliveries with rapid-pull-downs.

Medical/ Scientific

Because our compressors can be powered by low DC voltage, regulatory certification is greatly simplified.

Grid Power

Masterflux offers a solution for DC systems running on solar, battery, or other off-grid power sources.


Our technology can be found in military applications from the use of chiller technology for cooling a soldier to powering thermal systems for electronic cooling.


With demanding requirements for electronic cooling, Masterflux is at the forefront of the development of new cooling concepts for electronic systems.

Mobile Containers

Compact and reliable Masterflux used by global logistic services.
