Insulations
The boxes consist of galvanised sheet steel and are lined with
sound and heat insulation. The following insulations are
possible:
I0
=
Without insulation (standard)
I1
=
Thermal insulation made of polyethylene 10 mm in
thickness, particularly suitable for avoiding
condensate formation in the supply air box
(cooling).
I2
=
Sound and thermal insulation made of mineral wool
20 mm in thickness, particularly suitable for
reducing sound pressure and avoiding condensate
formation.
I4
=
Sound and thermal insulation made of mineral wool
40 mm in thickness, particularly suitable for
reducing sound pressure at frequencies below 100
Hz, and avoiding condensate formation. (Not
compatible with spigots >DN123).
