W (Width)		mm
D (Depth)		mm

2. Enclosure material Heat transfer coefficient

W/m²K

3. Location of installation

Units of Length: Temperature Unit:

4. Enclosure position

Free-standing single enclosure	Free-standing first or last enclosure	Free-standing middle enclosure
Wall-mounted single enclosure	Wall-mounted first or last enclosure	Wall-mounted middle enclosure
Ground-mounted single enclosure	Ground-mounted first or last enclosure	Ground-mounted middle enclosure
Ground and Wall mounted single enclosure	Ground and Wall mounted first or last enclosure	Ground and Wall mounted middle enclosure

Units of Length: Temperature Unit:

5. Heat dissipation

The heat dissipation (=self-warming) of all installed electrical load (e.g. transformers, relays, semiconductors, bus bars, etc.) has to be taken into account if components are operated continuously.

6. Climate

to maintain a minimum temperature inside of the enclosure and to avoid low temperatures

Lowest ambient temperature		°C
Desired minimum temperature inside of the enclosure		°C
(lowest temperature inside of enclosure to ensure all equipment inside of the enclosure will work properly)
Temperature difference		K

to maintain a specific humidity level in an enclosure to avoid condensation

Highest ambient temperature		°C
Highest ambient humidity (RH)		%
Desired humidity inside of enclosure (RH) (max. 65% recommended)		%
Height (above sea level) max. 2000 m or max. 6500 f		m

Required heating performance

The required heating performance can also be attained by combination of multiple heaters/fan heaters.

Errors and omissions excepted. STEGO Elektrotechnik GmbH does not assume liability for the accuracy of statement. Calculated heating performance must be verified by the user under real application conditions.
