Heat Recovery
The air fl ow from the fan cools down oil and
compressed air, that warms up when pas-
sing through the radiator.
The recoverable heat represents about
85% of the power installed in the BLADE
series machines.
The heat produced can be conveniently re-
covered and used to heat rooms.
Any duct should be adequately sized and,
if necessary, shaped in such a way to allow
for a correct use during Winter and the ou-
tput of hot air during Summer.
The duct to recover/output hot air should
be designed by a competent engineer and
should limit the load loss at approximately
20 Pa.
If the duct offers greater resistance, an au-
xiliary extractor should be used to prevent
any overheating of the machine.
As an example, a duct with a higher or
equal section to the coming out of the ma-
chine (the output grid on those versions
equipped with a soundproof case), made
up of some 10 m of straight duct and two
90° elbows properly connected, allows the
maximum tolerated limits to be maintained.
However, it should be noted that 10 Pa in-
crease corresponds to some 2 - 3 °C incre-
ase in operating temperatures.
As for the recoverable heat, it should be no-
ted that 1 kW of installed power allows for
the heating up a volume of about 30 cubic
meters by 1 K (1 kW = 860 kcal/h).
In the Section on “TECHNICAL DATA” atta-
ched to this manual the values required to
realize that which is mentioned above are
indicated.
