This compact heater is designed for many different applications including electrical and electronic enclosures, display panels, access and parking control systems and personnel booths.

To determine the required heater size follow this equation:

PH = (A x ΔT x k) - Pv
PH = Required heating power for your application in Watts (W)
Pv = Heating power generated by existing components (e.g. a transformer) in Watts (W)
A = Exposed enclosure surface area square meters (m²)
ΔT = Temperature differential between the desired minimum interior temperature and lowest possible external temperature of the enclosure in Kelvin (K), 1.8°F = 1°C = 1K
k = Heat transmission coefficient of the enclosure material used:
    Stainless Steel: 3.7 W/m²K
    Painted Steel: 5.5 W/m²K
    Aluminum: 12 W/m²K
    Polyester/Plastic: 3.5 W/m²K

For outdoor applications it is recommended to double the heating power.
