CyberRack Active Rear Door
Efficient and targeted rack cooling
The CyberRack Active Rear Door 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 CyberRack Active Rear Door, 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
- Suitable for any rack
- The active heat exchanger doors can be used independently of existing precision air conditioning units, or can supplement them.
- Maximum energy efficiency thanks to high rack inlet temperatures
Most important features
- Less load on the room air conditioning, because the heat is discharged directly from the rack
- Maintenance-friendly design
Most important technical data
- Cooling capacity (kW): 18.8 – 32.3
- Suitable for any rack
- The active heat exchanger doors can be used independently of existing precision air conditioning units, or can supplement them.
- For air conditioned server racks in data centers with and without raised floor
- Maximum energy efficiency thanks to high rack inlet temperatures
- Via the ac unit, the server rack becomes heat-neutral, as no warm return air is emitted
- Return and supply air sensors ensure uniform temperature distribution under varying server load
- EC fans for low electricity consumption
- Targeted cooling of high-density racks
- Less load on the room air conditioning, because the heat is discharged directly from the rack
- For data centers with and without raised floor
- Maintenance-friendly design

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 Once the rack door has been replaced by the adapter frame, the CyberRack unit can be hung in the adapter frame and connected to the chilled water supply.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 CyberRack Active Rear Door 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

Test Center
AC server racks: Test Center
In our state-of-the-art, 700-square-meter Test Center with its various climate chambers, we can perform a variety of tests on precision air conditioning units and chillers. During the development of the CyberRack Active Rear Door, we were able to test and optimize it under all climatic conditions encountered around the world.
In addition, we offer you the opportunity to book a witness test for server rack ac units in our Test Center. This allows you to have the desired air conditioning system tested according to your exact specifications, creating transparency and providing you with information about your system’s performance and energy consumption.
