Advanced Cooling in 4U

Compact. Efficient. Scalable.
nVent SCHROFF

Designed for high-performance electronics, the 4U LHX combines air-to-liquid cooling, intelligent monitoring, and compact integration to support higher rack densities. As computing power continues to rise, so does the challenge of managing heat within the rack. The compact 4U LHX offers a practical way to bring liquid cooling closer to the source, supporting higher-density deployments while fitting into 19” cabinets with at least 800 mm depth.

Harwin M300 Power Connectors

Rugged 10A Connections at 3mm Pitch
Mouser
