200/300/400 W Heater
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 ∆T 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)
∆T = 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.
