1.0 Structure
INNOV@DM-R units are designed with a self supporting frame and all components are made inside using sophisticated
computer driven machines and special tools. All sheet metals are galvanized and all external panels are powder coated
RAL 9002 giving to the units the image and the quality like last generation of IT devices. Units are completely closed and
only frontal access is requested. Anyway it is also possible to have side access in order to reach the steam piping and
the drain pan, or simply to substitute a damaged side panel: all this problems are very rare, but with INNOV@DM-R
units it is possible to solve them. The shape of the units is characterized with the rounded edges with R = 26,5 mm
radium this feature is obtained using special tools and gives both a good aesthetic and advantages against injuries. The
compressor compartment is separated from the air flow and the special internal design allows the simple dismounting
of the upper part of it ensuring an insuperable accessibility to all refrigerating components.
All fixing elements are made in stainless steel or in non corroding materials. The dray pan is made in stainless steel in
order
to ensure long time operation without damages.
All panels are thermally insulated with a polyurethane foam class 1 according UL 94 norms: this material, thanks to the
open cells, gives good performances in sound absorption. As an option, sandwich panels are available: in this case
mineral fibres are closed between the panel and a second sheet of metal giving the maximum in terms of internal
cleaning. Double skin panels are classified between non flammable materials class A1 according DIN 4102 norms: the
sound insulation is better than the standard solution, but the internal reflected sound power will increase the amount in
delivery side (+2dB).
