  1. New product for high heat density cooling Climate Solutions Sweden now introduce the rear door OnRak cooling unit in cooperation with Airedale and will with this product together with our Climate Ceiling products also cover the highest demands for cooling of Telecom and Data applications in the most efficient and energy saving way.

  2. High density rear door cooling > Compact rear door heat exchanger > Energy Efficiency Ratio over 100 > Up to 33 kW variable cooling > Designed to fit 42 - 48U racks > Depth 200mm > Can be supplied with an universal adapting frame adapted to fit a customer-specific rack OnRak integrated with rack cabinet

  3. Maximising uptime > n+1 fan configuration > 'Door open' air flow management > ‘Hot swappable’ fan management The OnRak cools hot air within the server rack before it reaches the room

  4. Key technical data > Two product configurations: n (100% air volume); optional n+1(75% air volume) > Cooling capacity: 33kW (n); 28kW (n+1) > Variable speed fans for precise cooling between 3 – 33kW > EC axial fans for ultimate efficiency: EER of 108 (n); 174 (n+1) > Advanced AireTronix control system solutions > Flexible water connections maintain cooling when the door is open > Self-regulating constant flow control > Water detection alarm > High efficiency aluminium fin heat exchanger and integral coil guard

  5. Simple connections to customer-specific rack

  6. EC axial fans for ultimate efficiency at part load As an example, an OnRak with EC fan technology and 23kW of Heat load uses 0.161kW of power and has an EER of 144. A traditional close control Unit delivering same amount of cooling uses 1.3kW of power and has an EER of 17. Over a year, the OnRak in this example will Consume 1,410kWhs of power against 11,388kWhs of the close control unit, representing a saving of 88% in power input.

  7. Pressure differentialmanagement By managing pressure at the rear of the server rack, the OnRak controls its fans to ensure they mirror the fans cooling the servers inside the rack cabinet. The server fans draw air through the servers to the back of the rack where the OnRak’s fans pull the air from the rack and discharge it into the room.

  8. Optional n+1 fan configuration enhanced by smart control logic and EC fan technology, gives the OnRak built-in redundancy and excellent part load efficiencies, increasing OnRak’s EER from 108 to 174 during part load operation. n+1 fan configuration for increases efficiency and uptime
