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
not exceed 65°C above ambient.

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.
