Free enclosure thermal calculation software Released 21 September 2001 The latest version of Pfannenberg's PC-based free thermal calculation software is supplied on CD, fully compatible with Windows 9x, ME, 2000 and NT. It is a very powerful tool, enabling engineers to calculate the cooling (and heating) requirements for a project. The program is user-friendly, with data entered into a sequence of drop down menus. Maximum and minimum ambient and internal temperatures are entered, as is the maximum expected relative humidity. Users can then choose the enclosure from a predefined database, or enter their own values for size and dissipation. The effects of selecting the enclosure material to be steel, stainless steel, aluminium or plastic can be easily seen. The thermal load to be dissipated can either be calculated automatically from predefined settings for circuit breakers, fuses, lamps, power supplies and other common components, it can be entered as an overall figure or the permissible load with or without assisted cooling can be calculated in reverse by defining the acceptable temperature excursions. The appropriate filter fan, cooling unit or air/water heat exchanger from Pfannenberg's range is offered by the programme; if heaters are required to stop condensation problems during periods of low temperature, the program will also show the heat input to avoid condensation and to maintain the required minimum internal temperature. *** Ends: 212 words *** Notes to Editors.
