with no loss of space

Show video

Cooling for network and server enclosures

Space-saving installation of the internal unit between the 482.6 mm (19˝) level and side panel
Optimum support of IT-compatible, “front-to-back” air routing
High level of fail-safeness guaranteed by availability of single and redundant variant
Cooling of TS IT racks and Micro Data Center
- Possible TS IT/LCU DX combinations

Refrigerant-based split cooling unit comprised of an internal unit (evaporator coil) and an external unit with integral compressor (inverter-controlled)
External unit is sited outside the building
Available in two power classes 3 kW and 6,5 kW

Maximum energy efficiency by cooling the individual rack, rather than the whole room
Efficient operation thanks to EC fan technology
Optimum adaptation of the compressor output to the current heat load of the IT rack with inverter control
Ultimate security with optional alarm forwarding via CMC III

High availability designed for continuous, 24/7 operation
Absorbed thermal energy is emitted via the external unit directly to the ambient air
The internal and external unit are connected with refrigerant, data and supply lines
Control of the server inlet temperature
