- Benefits
- Mounted on the rear of the server rack so that the thermal load of the server rack does not have to be dissipated by the ventilation system
- The heat pipe ensures even heat distribution in the heat exchanger, so that the heat exchanger always has a balanced heat load
- A door opening angle of 135° allows rear access to the server enclosure and makes assembly and configuration inside an enclosure easier
- Optimum energy efficiency, as there is no electrical power consumption whatsoever
- Applications
- Air-water heat exchanger for retrofitting to TS IT racks while operational
- Function principle
- The stand-alone unit replaces the rear door
- The waste air is cooled down to room temperature. The heat energy absorbed by the water is transported to the external cold water supply, where it is cooled back down to the required inlet temperature.
- The heat exchanger uses the airflow from the IT equipment and does not require any additional fans for cooling
- Minimal upstream and downstream pressure losses, despite the very compact design
- Water connection from below only
- Colour
- RAL 7035
- Design
- Rack cooling
- Note
- The air throughput (heated waste air) from the active 482.6 mm (19") components installed in the enclosure must be sufficient to overcome the pressure loss from the perforated heat exchanger rear door
- The total cooling output refers to an outlet temperature of 24 °C

- Product description
- SK LCP Hybrid CW, WHD: 600x2000x105 mm, 20 kW
The unit takes up the heat losses from IT components installed in an IT
rack and thus prevents dissipation of this heat at the place of
installation. The temperature of the room air is maintained at the
server air inlet temperature. The integrated air/water hybrid heat
exchanger with heat pipe guarantees a cooling output of up to 20 kW.
Heat pipes ensure even heat distribution over the exchanger in case of
inhomogeneous component installations in the rack; the IT rack is to be
fitted with the air baffle plates which are available as accessories so
as to form a "funnel" towards the rear and in this way to guarantee 100%
heat transfer via the heat pipe, even distribution of the heat losses
and thus full exploitation of the heat exchanger surface. The unit is
mounted at the rear on 600 mm wide IT racks with fixings on one side.
With its external frame construction, the heat exchanger does not occupy
space in the rack - the full server rack is thus available for the IT
equipment. Thanks to the high-performance heat exchanger and its special
corrugated membrane structure with hydrophilic coating, the exhaust air
flow from the servers is not impaired. The unit can be swung away from
the rack in the same way as a ventilated rear door. The opening angle of
the unit is 130°, also in combinations with several units in a suite.
The IT components installed in the IT rack use their own fans to route
the warm air flow to the air/water hybrid heat exchanger. The heat from
the warm exhaust air flow from the IT components is dissipated by way of
the air/water hybrid heat exchanger. No additional fans are required on
the unit for the cooling of the IT components. The air/water hybrid heat
exchanger results in a minimal pressure loss over the IT components. To
further reduce the pressure loss on the air side, additional air baffle
plates may be installed in the roof and floor areas in the 600 mm wide
IT rack (not included in the scope of supply). The air baffle plates do
not hinder the accessibility for cabling and mounting of the IT
components. The cold water connection of the LCP Hybrid is to be found
in the side door frame. The connection point for the feed and return
lines (DN 25, 1" internal thread) is fixed on the unit and is not turned
when opening and closing. Optionally, the cold water supply to the unit
can be realised by way of an external connection hose DN 25 / PN 16,
length 1 m (not included in the scope of supply).
