Rear Door Heat Exchangers
Elevate Performance with Adaptable Solutions
RDHX or Rear Door Coolers, are chilled water cooling doors that fit onto a IT rack. The air is pulled through the rack by the fans or pushed through by the server fans for the passive rear door (no fans). The RDHX Pros slimfit design of 281mm is the industries smallest footprint device with fans & without fans it is only 241mm
Benefits of Rear Door Heat Exchangers
Rear Door Heat Exchangers bring the cooling directly to the servers being has close as possible before converting to liquid cooling systems. Cooling has never been more simple. the RDHX Pro from nVent has a performance of 78kW at 14C and a 44kW performance at 24C. This aligns with the recommended ASHRAE Table 3.1 2021 Thermal Guidelines for Liquid Cooling. The RDHX Pro can also be retrofitted to ANY IT Rack.
RDHX Rear Door Cooler
The RDHX pro has hotswappable Fans, PSUs & Controllers for enchanced service and maintenance flexibility,reducing costly service callouts ensuring maximum uptime. All while the door remains closed! The RDHX pro is optimized for free cooling bringing the cooling systems next to the servers ensures maximum effciency for your data center in the next generation of AI servers
Efficient Climate Control
Controlling the rack temperature is a no brainer in the world of AI servers, the cooling systems need to be effcient and predicting downtime and temperature spikes in the rack can be nearly impossible. The RDHX pro ensures this is minimized.
