Coolcentric Rear Door Heat Exchanger - Standard (RDHx)

The World's Most Efficient, Flexible and Cost-Effective Cooling Solutions for Today's Sustainable Data Centers

Data center cooling can account for as much as 55% of a data center's total annualized operating cost, and as the cost of energy continues to increase, data center operating expenses grow exponentially. In addition to these rising energy costs, system consolidation initiatives have increased the number of blade servers residing in rack-mount enclosures, creating significant cooling challenges for data center managers and designers.

As the average heat density per enclosure increases, it becomes increasingly difficult to provide the cooling necessary to properly operate the data center. In some cases, the cooling that must be provided is two times what the heat loads truly require, due to inefficiencies within the cooling system. Data center managers and designers are now looking beyond the typical perimeter cooling topology using computer room air conditioners (CRAC) because the needs of today's data centers have surpassed the capabilities of typical CRAC units.

Coolcentric Data Center System Cooling Solutions

Coolcentric data center system cooling solutions are the best medicine to lower data center system cooling costs. Coolcentric Rear Door Heat Exchangers (RDHx) can reduce total energy consumption by 90% and decrease white space by 80% when compared to common CRAC units. Coolcentric RDHx solutions can lower your data center total cost of ownership by as much as 50%.

Coolcentric RDHx provides unmatched reliability, flexibility and cooling performance, all while reducing operating expenses. The RDHx attaches to the back of most industry standard enclosures. Chilled water is fed to the specially designed coil inside the RDHx. The rack-mount devices eject the hot exhaust air through the coil, transferring the heat to the water and ejecting cool air out of the RDHx.

Coolcentric Rear Door Heat Exchanger Benefits:

  • Completely neutralizes heat loads of up to 20kW
  • Uses a passive system – the rack-mount devices move the exhaust air through the RDHx
  • Requires no electricity at the RDHx, reducing operating costs and carbon footprint
  • Has no moving parts to fail
  • Has no fans, which means no noise and no points of failure
  • 100% Sensible cooling - no condensate issues
  • Can be deployed on existing configurations without rearranging enclosures or interrupting operations
  • Installs in 50 minutes

Liquid Cooling Technology

Liquid cooling technology in data centers has been around for more than 45 years and is field-proven. Liquid cooling can remove 3,500 times more heat than air can. Coolcentric's award-winning patented data center cooling solutions are based on IBM Cooling Technology. With Coolcentric data center equipment cooling solutions, cooling is brought right to the source of the heat – the IT enclosure. Close coupling the RDHx to the enclosure provides the ultimate in heat containment.

RDHx Deployment

The RDHx can be deployed in existing data centers or used as the basis of a cooling design. Designed to be adapted to many of the industry leading models of IT enclosures, the RDHx can be deployed most anywhere. Top- or bottom-feed designs give users flexibility for planning distribution of the chilled water.
