Overview

Built around the heat load, not around a rack size.

This in-rack CDU is tailored for cold plate liquid cooling systems. Its compact design fits standard 19-inch racks without occupying additional floor space. Dual-pump redundancy and variable-frequency circulation hold precise temperature control while significantly reducing the data center PUE.

Heat exchange, fluid replenishment and monitoring are integrated into a single unit, so it can be deployed independently. Built-in multi-level protection against leaks and over-temperature, together with visualised smart O&M, make it suitable for edge computing and for retrofitting small-to-medium AI computing rooms.
