10. EXTERNAL VERSION OF THE KLIMOR EVO AIR
HANDLING UNITS
KLIMOR EVO units can be adapted to work in outdoor con-
ditions. The dierences between the roof version of the air
handling units and the standard version are specied below:
a) Housing
All gaps between the xed panels of the cover type and the
aluminium frame are lled with sealing compound.
b) Air intake/outlet
The air intake/outlet is made as a ventilation tting with
steering wheels and a net. Its role is to cover the air inlet/
outlet from rain, wind and solids larger than 10×10mm.
It’s screwed to the damper or the air handling unit prole.
Mounting on the front wall or other (e.g. side) wall after
equipping the air handling unit with an empty section. It is
possible to mount additional elbows or ducts.
When the inlet is mounting on the side of the unit, the sec-
tion is equipped with an a drip tray for collecting conden-
sate (rainwater).
For the facing walls of the air inlet and outlet, if the outlet
is above the inlet, additional ventilation elements (duct or
knees) should be used on one of the air direction, to elimi-
nate the possible impact of both air jets.
c) Air dampers
The shut-o dampers are mounted outside the unit. Such
location is possible by hiding the blade drive in a double al-
uminium prole. The damper actuators are covered, but the
actuators with a higher degree of protection min IP54 are
required.
d) Exchangers
Water exchangers (heaters) are equipped with anti-freeze
protection by an anti-freeze thermostat in the air (only avail-
able with the supplied complete control system).
The heater collector stubs can be led inside the unit in a way
that allows for installation of pipelines, supply and return,
through the ceiling in the space between the unit frame
or inside. It is also possible to install the exchanger control
node in an additional section.
e) Roong
