To simplify the often time-consuming and complicated calculation of enclosure cooling and heating require-ments use Rittal’s Therm 6.3 software.
Input the dimensions and position of your panel, together with the heat loss of the equipment installed, the ambient temperature, your preferred internal temperature and details of the available power supply, you can then select a cooling or heating solution specific to your project requirements.
A user-friendly interface guides you step-by-step through the selection process and at the end of the calculation, you receive a detailed report that not only shows the selected product, but also the net heat transfer through the walls of the enclosure. In the case of cooling solutions, the internal temperature that would be reached without climate control.
All evaluations are based on the requirements of IEC/TR3 60890 890 AMD 1 and DIN 3168 for enclosure cooling units and so this useful tool also gives considerable peace of mind that suitable components have been chosen.
Enclosures can be selected from Rittal ranges or alternatively, the dimensions of bespoke cabinets can be entered manually. The heat dissipated by installed equipment can be input directly, calculated using actual measured enclosure internal and ambient temperatures or selected from a database of standard components.
Use an online version or download the offline version of Therm 6.3 from the Rittal website.

Now may be the time to investigate available solutions to the problem of overheating panels. Rittal have a large range of cooling products that will address the problem.
Rittal’s TopTherm fan-and-filter units are an energy efficient means of cooling enclosures but require a clean and cool environment to operate effectively. Air-to-air heat exchangers have separate internal and external air paths, preventing dirt and dust from entering the panel, but still require a cool ambient air to deliver the required cooling.
Cooling units also have separate air circuits but are capable of cooling the air inside an enclosure to a temperature lower than that of the ambient as well as maintaining a clean internal environment. In the case of thermoelectric coolers, the Peltier effect is used to deliver modest amounts of cooling, typically to small panels, offering a lightweight and compact solution. Units from the Rittal TopTherm Blue e range incorporate a refriger-ant circuit and so have larger nominal cooling capacities, up to 4 kW.
Air-to-water heat exchangers can maintain the air inside a panel at a temperature lower than that of the surrounding air and have an additional benefit of allowing heat to be dissipated remotely. Water is the cooling medium used to transport thermal energy to an alternative location, where it may be discharged without increasing the temperature in an already warm environment. To complete the chilled water system a Rittal chiller can be used to return the water to its’ original condition before recirculating to the heat exchanger.
