Electrical enclosure heater calculator.

Find your enclosure s total surface area by entering its dimensions here. 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. This calculator has a maximum temperature rise of 140 f or 78 c step 1.

Sales and support centers emea. Choose from a wide range of capacities power inputs mounting options sizes and type ratings. Determine the heat generated inside the 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. For heat transfer from the outside calculate the area exposed to the atmosphere except for the top of the control panel. Approximations may be necessary. Saginaw control and engineering.

To use this calculator appropriately one must first quantify the amount of heat generated by components inside. The graph can be read to determine expected temperature rise.
