RAB-KL-ETE-Xx, RAC-KL-ETE-Xx

Roof cooling unit ETE. Specially designed for the installation to the top of the cabinet.

For active temperature management we offer high quality STULZ- Cosmotec A/C units under the Triton brand. These compact A/C ETE units are designed to cool equipment in every single data cabinet (RDE cabinets and RIE cabinets with IP54 protection). These A/C units are intended for both industrial and office environments thanks to their RPM management of the cooling fan in the compressor circuit. The A/C unit adjusts the RPM speed of the fan, which is a major cause of a noise. The A/C RPM adjusment is based on the current use of the cooling output inside the cabinet. It has a positive affect on the noise reduction of the unit when the maximum output capacity is not needed.


The A/C unit has two separate circuits for air circulation:
1. The inside circuit, which cools all installed equipment and enters the A/C unit, where the hot air is transferred to a cooling medium.
2. The cooling circuit controlled by the compressor, which is cooled by an air stream that takes the excess heat away

Thanks to its arrangement, the air from outside is not mixed with the air from the inside of the cabinet. So the humidity inside the cabinet is not affected. Excessive humidity can condense on the equipment or can freeze inside the cooling unit which can lead to damage. It is very important to set up the A/C unit correctly and th consider the surrounding temperature and humidity. It is also possible to equip our data cabinet with a door sensor, which automatically shuts the compressor off when the door is opened. The A/C unit may be controlled by an electrical unit, which includes thermostats in two different parts of the cover. There are several options for installing such A/C units.

The A/C unit can draw in the hot air and blow out cold air along the side panels of the cabinet or it can be installed on the front/rear side accodring to the customer‘s requirements. For the A/C unit to function properly, itis necessary to provide it with sufficient air circulation and an appropriate temperature. The unit has special sensors which monitor the space from surrounding objects. For more information please refer to the manual of each A/C unit.
