4 Planning
Room temperature control
Radiant tube systems for the full heating of large
rooms 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:
Tab 1: Minimum suspension heights [see Fig 4]
Key:
A = Minimum height when hanging horizontally
* Please contact Schwank for determination of suspension
heights on other ambient temperatures

Tab 2: Safe distances [see Fig 4]
Key:
a = Minimum radial safety distance [inside radiation area]
b = Minimum upper safety distance when hanging horizontally
d = Minimum lateral distance to supply pipes outside radiation
area
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.

application
Direction of radiation
Radiant tubes deltaSchwank can be positioned
only horizontal. For this purpose suspension steel
chains and cables are installed at the suspension
brackets.
