The plug fan has the impeller fitted directly to
the motor shaft and is built into a soundproof
unit casing. The fan is a single inlet, free-blow-
ing fan where the unit casing acts as fan
housing. The plug fan has an efficiency of up to
75% and a low noise level. The plug fan can be
supplied with EC motor (IE4), PM motor (IE4), or
AC motor (IE3). Fan impeller and motor are
statically and dynamically balanced.
The rotary heat exchanger is supplied in 3
types: Condensation, sorption hybrid and sorp-
tion heat exchangers. Generally, the rotary heat
exchanger has a high efficiency from 75% to
87% depending on operating conditions. It can
recover moisture and is the heat exchanger that
requires the least space. The sorption hybrid
exchanger recovers more moisture, and there-
fore contributes to the humidification of the
supply air. The sorption exchanger dehumidifies
the air more, making it particularly suitable for
dehumidifying the outdoor air, for example
before cooling.
The plate heat exchanger is supplied in 3 types:
Standard, high efficiency and counter flow heat
exchangers. Generally, the plate heat exchanger
has a high efficiency. It has separated airflows,
and thus the transfer of odors to the supply air
is avoided. There is no transfer of moisture
between the two airflows, and so it can also be
used for dehumidification. The standard cross
flow exchanger has an efficiency of up to 65%.
The high efficiency cross flow exchanger has an
efficiency of up to 75%. These two types are
supplied in two variants: One made of alumini-
um for comfort and one made of corrosion-
resistant plastic-coated aluminium for aggres-
sive environments. The counter flow exchanger
has an efficiency of up to 90% and is supplied
only in aluminium. The heat exchangers are fit-
ted with by-pass for capacity control and have
a built-in drip tray.
The run-around coil heat exchanger has an
efficiency of up to 70% and is used, where the
two airflows must be kept completely separate,
or where the airflows are at a distance from
each other. For example on 2 different storeys.
The heating coil is used for heating the supply
air. The heating can be effected by hot water or
condensation of refrigerant. These coils consist
of copper tubes and aluminium fins. Heating
can also be affected with electricity. These coils
consist of heating elements of stainless steel
and have built-in safety control system. In the
standard version the coils are built into the unit.
More variants and options are possible.
The cooling coil is used for cooling the supply
air. It can be effected by cold water or direct
evaporative refrigerant. A cooling coil for eva-
poration has the liquid distributor placed in the
unit. These coils consist of copper tubes and
aluminium fins. In the standard version, the
coils are built into the unit. More variants and
options are possible.
The change-over battery is basically a cooling
coil for cold water, which can also be used for
heating by changing the water temperature
from cold to warm as required. Typically used in
connection with heat pumps.
