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.
