Lehmann IT is expanding its range of compact cooling solutions with a new generation of 19″ server cabinets featuring an integrated DX side cooling unit. Designed for small to medium‑sized IT environments, these systems deliver cooling capacities from 510 watts up to 4,000 watts, making them ideal for decentralized installations or locations where space is limited.

The integrated DX technology refers to Direct Expansion cooling, a system in which refrigerant circulates directly through the cooling circuit and absorbs heat from the server cabinet without requiring a secondary chilled‑water loop. This direct transfer of heat allows for fast, efficient cooling performance and reduces the complexity of the overall system. The side‑mounted DX cooling unit uses a targeted airflow design that channels cold air precisely through the cabinet, ensuring reliable heat removal at the source.

An energy‑efficient rotary compressor provides stable operation while keeping power consumption low, creating a dependable and economical cooling solution for modern IT setups. A special protective coating on the external circuit components shields the system from dust and dirt, enabling filterless operation and reducing maintenance requirements over the long term. The compact design, optimized airflow, and straightforward handling make these cabinets a practical choice for organizations seeking a robust and low‑maintenance cooling solution.

It is important to note that the side cooling unit releases heat into the surrounding room, so the installation site should offer adequate ventilation to maintain optimal performance. With international certifications and optional remote monitoring, Lehmann IT provides a scalable and reliable solution for companies that need compact, high‑performance, and maintenance‑friendly IT infrastructure.
