Active Rear Door Cooling (ARDC)
Efficient and targeted rack cooling
The Active Rear Door Cooling is a heat exchanger door with EC fans for installing on the rear door of server racks. The server rack door is swapped for the Active Rear Door Cooling, which transforms the rack into an ac server rack that no longer discharges any heat load in the data center.
Product Overview
Most important benefits
- 100% removal of the heat rejection at source.

Climate. Customized.
From standard units to fully customized solutions
The ability to offer such a wide range to customers is the embodiment of our philosophy, "Climate. Customized.". Size, design or control: Active Rear Door Cooling is a model of adaptability and can be precisely adapted to your individual requirements. In addition, a variety of options and equipment versions are available to achieve the optimum result.
Applications for ac server rack
Air conditioned server racks: Benefits
Design and sizes
Compact design
- Less than 300 mm additional rack depth
- No need to reposition the server racks
- The servers can retain all the height units in the rack
Individual adapter frames make them suitable for any rack. They are available in 2 different heights and 2 different widths (42U and 48U, and 600 mm and 800 mm). Once the rack door has been replaced by the adapter frame, the CyberRack unit can be hung in the adapter frame and connected to the chilled water supply.
No mixing of hot and cold air
CyberRack Active Rear Door units are installed on the rear of the rack. The active heat exchanger doors cool the server right at the source and prevent heated air from entering the room (see illustrations below).
Control and monitoring
- C2020 controller for controlling and monitoring the air conditioning system
- Active temperature control: The controller regulates the fan speed in accordance with the measured supply and return air values.
- Direct connection to BMS systems via ModBus RTU protocol or Ethernet
Options
Thanks to the diverse options and equipment options available, you can perfectly adapt the Active Rear Door Cooling to your particular requirements regarding air conditioned server racks.
- Adapter frames for 42U and 48U racks with a width of 600 or 800 mm
- Differential pressure control for protecting the server rack fans against overpressure
- 2 or 3-way CW valves, also available as a pressure independent 2-way PICV
- Cooling capacity display
- Air temperature and humidity sensor
- Supply water temperature sensor
- Water warning system incl. sensor
- Flexible connection hoses
Pressure independent control valve
The pressure independent control valve (PICV) combines the functions of control, hydraulic compensation and flowrate measurement. The water flowrate required for cooling is set directly by the CyberRack control system.
- Low water-side pressure drops cut pump energy costs
- Lower investment and installation costs and faster start-up thanks to automatic hydraulic compensation
- The defined water flowrate ensures stable and precise control in all load states
- The cooling capacity of each individual server rack is recorded
