Electrical enclosure heater calculator.

Rely on nvent hoffman s full portfolio of enclosure heater solutions to help maintain stable temperatures for your equipment. To use this calculator appropriately one must first quantify the amount of heat generated by components inside. Find your enclosure s total surface area by entering its dimensions here. Choose from a wide range of capacities power inputs mounting options sizes and type ratings.

For heat transfer from the outside calculate the area exposed to the atmosphere except for the top of the control panel. The graph can be read to determine expected temperature rise. 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.

For example if you know the power generated inside the unit assume 10 of the energy is dissipated as heat. You can use this calculator to find the wattage you need. 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. Protect your critical enclosure assets from the harmful effects of low temperatures condensation and corrosion.
