Rittal Cooling Units: Maximum Energy Efficiency


Cooling units keep the enclosure internal temperature at a constant level, which is independent of the ambient temperature. The air routing meets individual requirements. Two separate circuits prevent the ingress of dust into the enclosure.


Cooling Units for Small Output Categories

Wall-Mounted Cooling Units


For external mounting or internal mounting in docs and walls using standardised mounting cut-outs. Integral electric condensate evaporation (from 0.3kW). Cooling output 0.3 kW - 5.8 kW. From 0.3 kW, also available in energy-efficient Blue e+ technology. Protection categories: IP54/IP55/IP56, UL Type 3R/4, 12 and NEMA 4X. Wall-mounted cooling units also available in chemical and outdoor versions.


Roof-Mounted Cooling Units


Doors, side panels and escape routes are kept clear thanks to the roof-mounted design. Electric condensate evaporation. Cooling output 0.55 kW - 4 kW. Output category 1.3 kW, also available in energy-efficient Blue e+ technology.





Modular Climate Control Concept


The cooling unit is integrated into the enclosure door and therefore blends in perfectly with the overall look of the enclosure. Easily exchanged for the existing door without any matching, even with the system operational. Cooling output up to 1.5kW - 2.5 kW.




Thermoelectric Cooler Total Cooling/Heating Output 80/80 W


The powerful, lightweight climate control units based on Peltier technology provide efficient cooling of command panels and small enclosures. Cooling/heating output 80/80 W.




Brand-new Design and Extended Smart Functions

(1) Inverter Control: Inverter technology allows you to set the speed of the compressor and fan with a voltage controller, for the precise cooling performance you need at any given time.

(2) LED Optical Fibres: The device status is immediately visible via LED optical fibres, even from a distance (yellow = non-critical error; red = serious error), helping to reduce machine downtime.

(3) Innovative Hybrid Technology: This innovative hybrid solution combines a compressor cooling unit with a heat pipe for passive cooling. The compressor only cuts in when passive cooling is no longer sufficient.

(4) Integrated Heat Pipe for Passive Cooling: The patented heat pipe dissipates heat from the enclosure as soon as the ambient temperature drops below the setpoint. In this way, high heat loads may be dissipated at lower ambient temperatures.

(5) Condensate Evaporation as Standard: Integral condensate evaporation as standard with cooling units from 300 W upwards.
