Planning; Position Of Suspension - Schwank infraSchwank D Series Technical Manual

4 Planning

Room temperature control
Radiant tube heating-systems must be equipped
with a temperature control.
Section heating is allowed without temperature
control.

Position of suspension

Suspension height
Radiant tubes must be positioned so that no one in
the radiation area is exposed to an extreme high
heat level. This is ensured when the minimum
suspension heights shown in the following table are
adhered to:

Distances to flammable materials in the
radiant area
Radiant tubes must be positioned so that the
surface temperature of:
 components with flammable materials,
 flammable equipment, stored flammable
materials
never rises above 85° C.

Direction of radiation
Radiant tubes infraSchwank D / calorSchwank D
can be positioned horizontal or at an angle [max.
30° from vertical]. For this purpose suspension steel
chains and cables are installed at the suspension
brackets.
