GENERAL CHARACTERISTICS
!
LEO KM mixing chamber works with LEO FB 25|45|65 fan heaters
creating heating and ventilation unit. It is the simplest way to provide
an efficient mechanical ventilation without additional systems.

Heating and ventilation units LEO KMFB are designed to operate
indoors. It is the simplest way to provide mechanical ventilation
in the building. With UVO roof fans and KTS control system they
form the complete ventilation system for the buildings with
medium and big cubic measure like industrial halls, warehouses,
department stores etc.
Mixing chamber is available in two versions:

CONSTRUCTION
MODULAR DESIGN
Mixing chamber consists of three
independent modules, which can be installed
in various configurations. It makes possible to
easy place them according to conditions of
installation place.
AIR FILTER
The chamber is equipped with EU3 class
cassette filter, which cleans the air supplied
to the room of solid particles like big pollens,
thick metallurgy dust etc. Filter module are
installed to allow easy maintenance.
RECIRCULATION
Mixing chamber is equipped with inlets
of fresh and used air. Used air inlet can be
installed on each side of the chamber. Volume
of supplied fresh air can be smoothly chosen
from the 0-100% range.
DESIGN
Mixing chamber is specially designed for
LEO FB heaters. The main objective of design
process was to create compact, aesthetic
unit. The other objective was to obtain as
low weight and dimensions as possible,
maintaining the best technical parameters.

INSTALLATION TIPS
P
P
P
Steady air circulation should be provided in the entire room.
P
P
Use of air ducts, which have local pressure drops is not
recommended. This may result in lower efficiency of the unit.
P
P
P
Heaters installed at the opposite walls
should be overlapped.
Air inlet should not be limited.

This is the system, which splits control signals from KTE board. It is also the
power supply system for LEO heaters and roof fans. Use of buffer makes
possible to control up to 5 units with one KTE control board. Additionaly, buffer
has warning lights, which inform about filters contamination, antifreeze alarm
or roof fan malfunction for each unit separately.
