How it works.

Precision 2-phase heat extraction

Our unique refrigerant technology leverages the liquid/vapor transition for unrivaled heat absorption capacity

What our customers say

Latent heat exchange

“…really extracts a tremendous amount of heat energy, a lot more than water can, and also has the added benefit that there’s very low pumping costs because you’re circulating relatively small amounts of refrigerant as opposed to many many gallons per cabinet.”
