Heating

Due to fluctuating temperatures, condensation can form in enclosures. This can lead to serious malfunctions or, worst case, to component failure. Convection heaters protect against low temperatures, thus preventing the formation of condensation. Furthermore, fan heaters provide air circulation and ensure constant temperatures in enclosures.

Heater Calculation

Calculation of required heating performance

Please select the Print preview prior to data entry if you wish to print the results of the calculation. Please contact us by e-mail of phone if you need assistance.

1. Enclosure dimensions

H=		in
W=		in
D=		in

2. Enclosure position

a)		Free-standing single enclosure
b)		Free-standing first or last enclosure
c)		Free-standing middle enclosure
d)		Wall-mounted single enclosure
e)		Wall-mounted first or last enclosure
f)		Wall-mounted middle enclosure
g)		Ground-mounted single enclosure
h)		Ground-mounted first or last enclosure
i)		Ground-mounted middle enclosure
j)		Ground and Wall mounted single enclosure
k)		Ground and Wall mounted first or last enclosure
l)		Ground and Wall mounted middle enclosure

Enclosure surface area:

ft²

3. Location of installation

4. Enclosure material

Heat transfer coefficient

W/ft²K

5. Temperature differential

Variations in temperature (e.g. day-night, summer-winter, climate zones) have to be taken into account. Please enter the maximum temperature differential or determine the temperature differential in the enclosure based on the maximum allowable interior temperature (Ti) and the maximum expected ambient temperature (Tu):

Lowest ambient temperature		°F
Desired interior temperature		°F
Temperature differential		K

6. Continuous stray power

The electrical load installed in enclosures (e.g. transformers, relays, semi-conductors, bus bars, etc.) generate heat when in operation. This self-warming is described as stray power, power loss or dissipation.
