1.1 Structure
INNOV@ units are designed with a self supporting frame and all components are produced 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@ units it is possible
to solve them. The shape of the units is characterized with the curved edges with variable 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).
