Electrical enclosure heater calculator.

Saginaw control and engineering. Protect your critical enclosure assets from the harmful effects of low temperatures condensation and corrosion. For example if you know the power generated inside the unit assume 10 of the energy is dissipated as heat. Find your enclosure s total surface area by entering its dimensions here.

Determine the heat generated inside the enclosure. For heat transfer from the outside calculate the area exposed to the atmosphere except for the top of the control panel. 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.

The graph can be read to determine expected temperature rise. You can use this calculator to find the wattage you need. This calculator has a maximum temperature rise of 140 f or 78 c step 1. 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.

Sales and support centers emea. To use this calculator appropriately one must first quantify the amount of heat generated by components inside.
