3.9. Cooling and exhaust air
Unit cooling:
The air for cooling the tubes and burners in the ca-
nopy section is sucked in through the upper fi lter mat. Ambient
air for cooling the tubes in the base section is sucked in through
the front fi lter mat in the base section. The fan collects the coo-
ling air coming from above and below, which is then blown off
through the exhaust-air fl ue (see Figure 3-20 and Figure 3-21).
Body cooling:
A body fan blows ambient air (if not equipped with
air-conditioning unit), or chilled air (if equipped with air-conditio-
ning unit), into the tanning space of the system (blue). The air
spoiler at the canopy pane directs this air towards the face. (see
Figure 3-22)
