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.
Anti condensation heater calculation.
Which electric heater would most efficiently maintain a 60 f temperature in an uninsulated 24x24x10 enclosure that is exposed to a temperature not less than 30 f.
Required heating power of thermal management products.
Anti condensation heaters also called cabinet heater or enclosure heater is used to protect cabinets and electrical panels against condensation due to temperature variations.
Find your enclosure s total surface area by entering its dimensions here.
Heating elements regulators fans and our accessories help you to optimize operating conditions and to reach maximum protection for your installations.
The required heating performance can also be reached with a combination of heaters and or fan heaters.
Calculation of anti condensation power all electrical cabinets emit certain amount of heat to the surroundings through the surface.
And condensation for outdoor applications double the heating power requirement.
Based on the data you entered into this calculation tool your application does not need to be heated it should be ventilated or cooled instead.
Step 1 calculate the total enclosure surface area.
In addition to the ambient temperature you can also add humidity values into this calculation depending on whether a minimum temperature has to be maintained or if a specific humidity level must not be exceeded.
Please check if your entries are correct and re enter if necessary.
These are directly proportional to the resistance s of the wall s components to heat flow and moisture vapor flow and air leaks.
Also you can calculate the approximate wattage required by using the equation w 2dl where w is the heat in watts d is the outside diameter of the stator laminations in inches and l is the length of the stator core in inches.
To do the wall condensation or dew point calculations you need to know the temperature and vapor pressure gradients through the wall or ceiling.
This calculator has a maximum temperature rise of 140 f or 78 c step 1.
So the required anti condensation power is proportional to the effective surface area of the enclosure.
In just four steps you can determine the heating performance required for your application.
You can use this calculator to find the wattage you need.
