Rear door heat exchanger · chilled-water rack cooling. Localized, energy-efficient cooling directly at the rack, engineered for HPC workloads and warm-water free cooling.
The EDGECELL Cooling Door replaces the rear door of a standard IT rack with a chilled-water heat exchanger and a wall of six smart fan modules. Hot exhaust air is cooled before it leaves the rack, so the room stays neutral and the facility can run warm-water loops with free cooling for most of the year. Tool-less, hot-swappable components ensure maximum uptime and easy servicing, extending system lifetime.

| Size variation | Custom |
| Return air filter · hose package · door switch · external temp sensor | Accessories |
| Power supplies | Dual — standard |
| Leak detection | Optional |
| Water sensor | Optional; order corresponding hose package |
* Water quality requirements must be maintained to avoid problems during operation. Usage of appropriate anti-corrosion and frost protection agents is recommended. ** Below 14 °C / 57 °F there is an increased risk of condensation. Water temperature must be maintained at 2 °C above dew point. It is recommended to use the cooling door in conjunction with a CDU to mitigate condensation.
