Control Panel Heating (Typically The Panels Are Located Outdoors and Require Heating)

Calculations:

1). Calculate the total enclosure surface area in Square Inches.
2). Determine the temperature rise above ambient required (Temperature Gradient).
3). Using the graph below determine the heat loss in Watt/Sq.In..
4). Multiply the total surface area by the heat loss to determine the total wattage required.

Note: Subtract the wattage from internal control panel components from the total heat loss wattage required to determine the appropriate heating element wattage required.

5). Select an appropriately sized Chromalox strip heater.
6). Select an appropriate Chromalox thermostat assembly kit as follows:

** Thermostats rated at 10amps@240VAC, and 13 amps@120VAC
