Electrical enclosure heater calculator. For heat transfer from the outside calculate the area exposed to the atmosphere except for the top of the control panel. To use this calculator appropriately one must first quantify the amount of heat generated by components inside. Protect your critical enclosure assets from the harmful effects of low temperatures condensation and corrosion. Find your enclosure s total surface area by entering its dimensions here.

Determine the heat generated inside the enclosure. Rely on nvent hoffman s full portfolio of enclosure heater solutions to help maintain stable temperatures for your equipment. Approximations may be necessary. 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.

86 755 2714 1166 americas. You can use this calculator to find the wattage you need. For example if you know the power generated inside the unit assume 10 of the energy is dissipated as heat. The graph can be read to determine expected temperature rise.

Choose from a wide range of capacities power inputs mounting options sizes and type ratings. This calculator has a maximum temperature rise of 140 f or 78 c step 1.
