An improperly sized cabinet enclosure heater can damage your electrical components and cost you in repairs. Depending on what’s in the cabinet, it can cause larger problems.
Cabinet Enclosure Heater Sizing
Start with the surface area – Measure the height, width, and depth of your enclosure. Find the Surface Area by: Surface Area = 2(length*width + length*height + width*height).
Find the temperature differential – by
First figuring out the lowest temperature your cabinet will experience where it is located (ambient temp).
Then you need to figure out what the desired operating temperature is for your enclosure. With these two numbers, you can figure out the temperature differential by subtracting the ambient temperature from the desired temperature.
Determining Wattage Requirements for Enclosure Heaters
|Temperature Rise from Minimum Expected Ambient Temperature to Desired Enclosure Temperature (oF)|
|Enclosure Surface Area – Square Feet||50||670||160||1340||320||2010||480||2680||640||3350||800||4020||960||4690||1120|
