Electrical enclosure heater calculator.

The wattage of the heater you need is determined by the total surface area of your enclosure and the temperature rise you need to produce. For example if you know the power generated inside the unit assume 10 of the energy is dissipated as heat. Approximations may be necessary. 86 755 2714 1166 americas.

Once total heat is calculated the calculator can be used to determine expected temperature rise based on the control panel size and type of enclosure. 46 31 420530 asia pacific. Protect your critical enclosure assets from the harmful effects of low temperatures condensation and corrosion. The graph can be read to determine expected temperature rise.

For heat transfer from the outside calculate the area exposed to the atmosphere except for the top of the control panel. Rely on nvent hoffman s full portfolio of enclosure heater solutions to help maintain stable temperatures for your equipment. Determine the heat generated inside the enclosure. This calculator has a maximum temperature rise of 140 f or 78 c step 1.
