Rittal Therm 6.3 – updated thermal

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.

Rittal EC fan-and-filter units with speed control

Rittal fan-and-filter units with EC (electronically commutated) motors should be the preferred choice for energy efficiency in enclosure climate control, as their operating ratio is significantly higher than standard AC fan-and-filter units.

Using fan-and-filter units always makes sense if the difference between the outdoor temperature and the internal enclosure temperature is large enough to dissipate the thermal output of the installed components. However, the fans mostly operate without regulation. In other words, they run constantly and always at full speed. In this situation, the savings potential offered by seasonal temperature fluctuations or temperature reductions in the building (e.g. on night shifts or through reduced waste heat in the enclosure) remains unused.

Further optimisation potential exists with an advanced solution using Rittal fan-and-filter units with temperature-dependent speed control. With a new sensor for controlling the speed of the Rittal EC fan-and-filter units, inherently up to 30% more efficient than comparable AC fan-and-filter units, power consumption can be drastically reduced yet again. The sensor measures the temperature within the enclosure and controls the fan speed as needed, right up to independent shutdown at below 20°C.

Replacing AC systems without speed control by EC systems with system control saves money, as shown in the following example: At a manufacturing plant with 50 fan-and-filter units (700 m³/h), run at full load for two shifts per day and five days a week, needing only 20% of the fan speed at night and weekends with reduced enclosure temperatures (20°C), EC technology and intelligent controls, can more than halve the energy costs.
