Unit type
Product description
The VPM 120-560 series is a ventilation and heat recovery unit with cooling and heat function specially
developed for commercial construction with an air change requirement of up to 5,600 m³per hour.
A VPM unit removes the "used" moist air from the building and in turn supplies "fresh" temperate air.
The energy in the extract air is recovered and transferred to the supply air via a unique combination of
active (heat pump) and passive (heatpipe) heat recovery. The high efficiency of the VPM series is due
to this unique design, which combines the best of two technologies. This improves efficiency so much
that the efficiency comes close to 100%. This means that the need for supply of heat during the cold
winter months is reduced to a minimum, and significant savings are achieved on the building's energy
consumption and a reduction in CO 2 -emissions. During summer time, the process is reversed so that
the supply air is cooled.
It is possible to select a heat exchanger in the cooling circuit. It makes it possible to utilize the excess
energy or waste energy created by the cooling process, for example heating hot water.
The unit can be controlled and monitored via our CTS602i control or CTS6000 control.

Accessories
Handle with lock cylinder
If you wish to be able to lock the service doors of the unit, it is possible to
purchase handles with lock cylinder and key.
VTZ Compressor
VTZ is a frequency controlled compressor that has a stable and constant
regulation. The compressor adjusts the operation according to the cooling or
heating demand, and thus will achieve a high COP value, which means low energy
consumption.
The VTZ compressor can be used with the CTS602i and CTS6000 automatics.
Shut-off damper
Shut-off dampers for external mounting are supplied in sets of 2 pieces. with
associated damper motor.
• For the CTS602i, a 230V damper motor is supplied
• For the CTS6000, a 24V damper motor is supplied
Water after-heating element
With a water after-heating element you can increase the supply air temperature
to the desired level. Water-heater can be built into the system and comes with
the necessary sensors.
The water-heating element is controlled using Danfoss Actuator, which is
connected to the plant.
The unit can also control external heating elements.
Electrical after-heating element
The electric heating element is prepared for mounting internally in the fan unit
VPM and is equipped with a binary power distribution.

Filter monitoring - Pressure transmitter
Displays the continuous pressure drop across the filter in the CTS control and
gives alarm when the filter needs to be changed at the final pressure drop preset
in the CTS control.
Humidity control
Humidity control can be ordered in the air handling unit according to the actual
humidity in the extract air - either externally or integrated in the plant.
In the control it is possible to choose either moisture control or CO2 sensor
Heating Cable
A 3 m long self-regulating heating cable can be ordered for frost protection of
the condensate drain.
Water trap with ball
To prevent "false" air from being sucked into the unit via the condensate drain, a
water trap must be established. When there is water in the condensate drain, the
water trap works very well, but in the summer months, when there is no
condensation of the extract air, the water trap will dry out and no longer prevent
"false" air. A Nilan water trap with ball ensures against "false" air throughout the
year.
Can only be used in the suction side of the unit in the VPM system.
Vibration absorbers
Vibration dampers (sylomers) for placement under the unit ensure effective
damping of the vibrations of the unit against the substrate.
Pressure control
The motor for the suction and / or supply fan can be controlled by one or two
pressure transmitters mounted in the suction and / or supply duct.
In the standard version, the pressure transmitters come with 5 m cable, including
power supply.
VPM 120-560 (English) BY NILAN
17

CO2 sensor
With a CO2-sensor installed, the fan speed can be pre-programmed to run at a
higher level when there is high CO2 - level in the extract air. CO2 level can be
programmed.
In the control it is possible to choose either moisture control or CO2 sensor
Top cover
If the unit is to be installed outside, it is possible to order a top cover for
protection against rain and snow.
18

Installation
Handling
Unpacking
The unit comes wrapped in foil. To protect the galvanized sheet metal parts from discoloration,
immediately remove the foil and then cover with a tarpaulin until the system is installed.
Transport after unpacking
Transportation of units when this is to be placed and installed can take place in two general ways:
• Lift under the unit with pallet lifts. VPM units with pre-assembled base can be lifted directly with
pallet lifts. VPM systems without pre-assembled base must stand on pallet when lifting with pallet
lifts.
• Lift with rope / straps on the system. If rope / straps are used, the mutual angle must be greater than
60 °. If, for reasons of space, this cannot be observed, a lifting beams or the like must be used.
Min. 60°
Lifting beams
ATTENTION
Visible transport damages must be reported immediately. Hidden transport damages must be
reported within 7 days. When notifying transport damage, photo documentation must be sent.
In addition, reference is made to Incoterm's 2010 terms of delivery, time limits for complaints,
limitation periods and limitation amounts, etc.

Installation
Positioning the unit
ATTENTION
Good clearance in front of the unit is recommended (see table). When positioning the unit, you
should always consider future services and maintenance. It must be easy to replace filters and
it must be possible to replace fans or other components. There must be space for easy cleaning
of the unit. When cleaning the unit, water may run out of cleaning and condensation drains.
There must therefore be space for mounting water locks at condensate drains as well as any.

ATTENTION
The unit must be level to enable proper drainage from the condensate tray.
ATTENTION
The unit produces little noise and only weak vibrations, but you should still take into account
potential vibrations that can spread from the unit to individual building components. In order to
separate the unit from its foundation, it is therefore recommended that you install vibration
absorbers under the unit. There should be approx. 10 mm distance to other building
components and to permanent fixtures.
