Controlled room temperature

Our simple end to end solution to effectively control the comms and data centre room environment is the ColdLogik Management System ‘CMS’

Each RDHx is intelligently managed for optimum efficiency by embedded computers which continually adjust the operational parameters in response to the heat removal demands temperature.

Total flexibility - Standard and non-standard ranges

Available as standard in 2 heights and 3 widths, with 7 variants from passive low duty (0.1kW) to active high duty (85kW per cabinet) 110kW version currently in design.

The ColdLogik CL20 rear cooler boasts the most versatile range available with non standard sizes supplied to suit individual requirements.

SAN & UPS cabinet cooling

Since its launch in 2007 the CL20 has been designed-in to many solutions, including the cooling of OEM SAN and UPS cabinets. Naturally it is imperative to retain the integrity of the OEM’s product and to this end USystems had already developed an overhead runner system ‘Zero Aisle’ - which negated the need to hinge the cooler to the OEM cabinet. The runner system can be fitted to the top of the cabinet or suspended from the ceiling.
