Coolcentric Rear Door Heat Exchanger - Low Density (RDHx-LD)
The Coolcentric® RDHx-LD is a new member of the Coolcentric family of rear door heat exchangers designed to extend available energy and cooling efficiencies, and resulting cost savings, to installations with low to medium rack densities of 5-12 kW. The RDHx-LD can be intermixed with other RDHx family products in a data center installation to accommodate low, medium and high density requirements. In addition, as rack heat loads grow, the RDHx-LD can be easily upgraded to higher capacity heat exchangers to satisfy growing cooling demands thus providing data center owners and operators flexibility and cost avoidance. The RDHx-LD can provide as much as 12kW of sensible cooling per IT enclosure, the standard RDHx up to 33kW and the Sidecar as much as 40kW.
Coolcentric heat exchangers are passive liquid cooled heat exchangers; Rear Door Heat Exchangers (RDHx) replace standard rear doors on IT enclosures, and the Sidecar is an in-row heat exchanger. The rack-mount devices draw cool supply air through the chassis. Heated exhaust air passes through the liquid-filled coil, which can neutralize 100% of the exhaust air before reentry into the data center. The Coolcentric heat exchangers employ specially designed fin and tube coils, protected by two 79% open perforated sheets, to maintain airflow through the IT enclosure. Close-coupled to the IT enclosure, the heat exchangers bring the cooling as close to the heat source as possible thus providing the ultimate containment solution. Taking up a minimum of floor space, the Coolcentric heat exchangers are flexible, efficient and space-saving cooling solutions for data centers.
