CoolRack DX:

August 2026 is running about 5 degrees Celsius above the long-term average in Germany, with peaks above 39°C — following a new all-time German heat record of 41.8°C set back in June. For server rooms without their own climate control, that quickly becomes a real operational risk: once rack temperature climbs too far, performance drops and hardware damage follows.

Lehmann IT's CoolRack DX is a fully integrated, air-conditioned server cabinet with direct-expansion cooling — essentially its own air conditioning unit built right onto the rack. A side-cooling unit delivers up to 14 kW of cooling capacity and, thanks to its plug-and-play design, can be operational immediately, with no separate building climate control required. The sturdy 42U construction with high load capacity provides stability, while modular airflow targets cooling directly at the installed hardware.

The CoolRack DX suits decentralized IT sites, small server rooms, and environments without existing climate control, where a self-contained cooling solution is faster and simpler than retrofitting building HVAC. For individual consultation on the right configuration, contact Lehmann IT.
