Temperature Controller

A controller for moderating water temperature, by changing fan speeds on a radiator that doesn't require any software configuration or user input.

RendeRex Smart Temperature Controller IoT Device


Our controller is found in every one of our liquid cooled workstations, which are in some of the most prestigious data-centers and offices around the region.

8x PWM channels

Eight PWM channels, each capable of supplying up to 1.5 Amps to multiple connected fans/pumps.

Built-In Safety Features

With a built-in sound alarm when temperatures rise above 40C, and automatic shutdown if water temperatures reach 50C.

No User Input Required

The entire fan curve is built into the firmware itself, meaning the RendeRex controller doesn't require any software configuration or user-input. Just plug & play.
