Enclosure cooler
The cooling of switchgear is becoming more and more important due to the increasing packing densities of electrical and electronic components. ritter & bader offers various systems for the air conditioning of switch cabinets:
If self-sufficient, low-capacity solutions are required, then refrigeration/air conditioning units can be an option. A refrigerant circuit provides the necessary cooling at the evaporator.Â
Plug-in appliances only need to be connected to a power supply; internal fans provide the necessary air circulation in the cabinet. The air circuit inside and outside is separated, there is no air exchange. If it is always ensured that there is a temperature gradient to be utilized between the internal enclosure temperature and the ambient temperature, a very economical type of cooling can be realized with so-called air-to-air cooling units. The heat from the air is transferred to the ambient air via the heat exchanger without air exchange.
For these types of cooling units, ritter & bader offers various mounting and installation options on the cabinet. External installation, partial installation and internal installation are all possible. The mounting surfaces can be side walls, doors or roofs.
So-called air-water heat exchangers are a very effective cooling solution. These are operated by cooling or cold water that flows through a heat exchanger and absorbs heat from the air (fans). There are various add-on and superstructure versions that enable very constant temperatures by regulating the air volume and/or the water flow rate. Installations in the base of the switch cabinet have proven to be very advantageous in terms of the low risk of water damage.
One advantage of air-water heat exchangers is the possibility of heat recovery.
