The OnRak is a highly efficient, compact rear-door heat exchanger designed to manage discharge temperatures from the server into the aisle space.

In dealing with the heat load closer to the source and with its slim configuration, the OnRak is highly efficient in floor space and power usage.

Part of the LogiCool range of IT cooling solutions, the OnRak increases uptime and offers an expandable cooling system that can be supplied with an industry standard data rack (42-47U) or a mating frame to fit a customer-specific rack.

Enhanced by smart control logic and EC fan technology, the OnRak has an Energy Efficiency Ratio (EER) of up to 166. Over a year it will achieve up to 88% saving in power input compared with a traditional close control unit with the same capacity.

Multiple OnRak units can be linked with an Airedale large capacity air cooled chiller. Substantial energy savings are achieved when the OnRak is matched with a free-cooling chiller.

Key technical data

  • High efficiency rear door heat exchanger
  • Variable speed fan for precise cooling between 3-35kW
  • Two product configurations: (n) 33kW cooling (100% air volume); for redundancy - optional (n+1) 28kW cooling (75% air volume))
  • Supplied with integrated rack or adapted to fit a customer-specific rack
  • EC axial fans for ultimate efficiency
  • EER of 108 (n); 174 (n+1)
  • Advanced AireTronix control system solutions
  • Flexible water connections maintain cooling when door open
  • Hot swappable fans to maximise uptime
  • Water detection and automatic isolation
  • Self-regulating constant flow control simplifies commissioning
  • High-efficiency aluminium fin heat exchanger with integral coil guard
  • Isolating solenoid valves (option)
  • Depth: 200mm
  • Operating weight: 75kg
