SideCooler DX can operate with coolant and are installed on the side of the rack, placing them especially close to the heat source. Fans can be replaced during operation. From individual rack cooling to bayed suite cooling, the Sidecooler offers maximum application flexibility. This SideCooler can be combined with other cold-water and coolant –based side coolers without any problems.
Ventilation between Sidecooler and rack is completely independent of room temperatures and noise emissions can be reduced to a minimum. An optional high efficiency heat exchanger with an extended heat exchanging surface enables chilled water flow temperatures of up to 30 °C at a server supply air temperature of 35 °C to be achieved (deltaT chilled water flow / server supply air K5)

The ventilators in the Sidecooler set the exact volume of air in motion that is required for forcing the warm air away from the servers. This prevents high volumes of air leakage and so results in energy savings. All Sidecoolers can also be used in Master-Slave mode, meaning that all the fans in an enclosure operate at the same speed. Altogether, a total of 64 Sidecoolers can work in one Master-Slave group.

The rear side of the rack row forms a warm aisle. This variant can completely replace an entire warm aisle enclosure. The open architecture at the front of the rack row enables redundant cooling to be used and also means that existing fire extinguishers in the room will also be effective for the rack row, thus eliminating any additional installation work.

In this type of ventilation architecture, an entire cold aisle enclosure is replaced. In combination with a warm aisle enclosure, the influence of cables on the flow of cool air can be significantly reduced. This variant is particularly suitable for racks with widths of 600 mm.

No, that is not possible, as the external unit and the Sidecooler DX have common communications interfaces, which are closely coordinated and adapted to each other. This is the only way to ensure secure data monitoring.
Yes. This is required to switch off the external unit during maintenance work, for example.
Before you install an external or outdoor unit on the outside wall /roof, the legal limits for sound emissions (residential, mixed, industrial areas) need to be checked.
The external unit’s maximum noise level can be found in the data sheets provided with each Sidecooler. If you have any questions, feel free to contact our customer service on +49 2741 283-770.
The minimum heat load is 30 % of the nominal heat load. If the heat load is lower than this, the Sidecooler constantly switches itself on and off. After the Sidecooler DX has been switched off, the external unit’s blocking time (at least 6 minutes) must be observed. During this time, the rack is not cooled and its temperature rises.
We recommend using a weather resistant Ölflex Classic 110 LT 2G1.5 mm² with wire ferrules on both ends.
Sidecooler models are available for open architectures (in connection with cold aisle enclosures), hybrid architectures (one side open, one side closed) and for closed architectures.
If an on-site condensate gradient pipe has been laid underneath the SideCooler, a condensate pump will not be needed.
The ASHRAE standard forms the planning basis for IT components.
Since 2011, there have been 4 ASHRAE classifications
Class A 1: server supply air temperature up to 33 °C
Class A 2: server supply air temperature up to 35 °C
Class A 3: server supply air temperature up to 40 °C
Class A 4: server supply air temperature up to 45 °C
Free cooling means energy-saving cooling without a chiller. The higher the cold water temperature, the longer free cooling can be used to dissipate the thermal energy generated by IT components. Free cooling also achieves a particularly low PUE value (Power Usage Effectiveness).
Due to its modular design, the Sidecooler DX is suitable for a variety of ventilation architectures. Its cooling capacity of up to 28 kW makes it ideal for racks and data centres in small and medium-sized IT rooms. Up to 6 fans can be installed during operation, allowing the cooling capacity to be adapted individually to current requirements. The Sidecooler DX allows an energy-efficiency label of A++ to be obtained, as a special power receiver is used for sub-cooling the refrigerant/coolant (R410A/R32) and the two expansion valves can be controlled individually. In stand-by mode, only those Sidecoolers actually required for cooling operate at the optimal power level. A high-performance heat exchanger (evaporator made of copper piping with pressed on aluminium fins) provides an additional increase in performance.
The pressure tested cooling circuit is filled with refrigeration machine oil. The weather-proofed drive motor is maintenance free and equipped with a thermal overload protector. Housing and frame are made of strong, galvanised steel sheet with an additional weather-proof polyester stove-enamel finish and sound insulation on the inside, which makes the Sidecooler a very low noise device. Operation requires a suitable outdoor unit.
Both Sidecoolers (DX and CW) are equipped with the SCHÄFER Logic Interface, a central operating unit, to enable integration in all current monitoring systems. A touch screen ensures easy operation and, with the help of 13 sensors, displays the relevant parameters, such as status overview of exhaust and supply air, flow and return temperatures, fan speed and valve opening. Access to the control unit is gained via HTTP(S) and SNMP v2c and v3, though parameter changes can only made after entering a password. The pull-out control box allows easy access and maintenance.
