🚪 RDHx Doors (Passive & Active Rear Door Chilled Water GPM, 50-80 kW Heat Capture)

Rear Door Heat Exchanger (RDHx) Calculator

Size active and passive Rear Door Heat Exchanger (RDHx / Motivair / Envicool) chilled water coils mounted to the back of high-density server racks: calculate chilled water flow rate ($55^circ ext{F to }65^circ ext{F CHW GPM}$), capture $100%$ of exhaust server heat ($50 ext{ to }80 ext{ kW per rack}$) before air enters the room, achieve neutral room conditions, and data center retrofit profits.
