Unit type
Product description
Unit type
Product description
The VPM 600-3200 series is a ventilation and heat recovery unit with cooling and heating functions developed especially for
commercial constructions with an air exchange requirement of up to 32,000 m3per hour.
A VPM unit removes the “used”, humid air from the building and supplies new, “fresh” air in turn. The energy in the extract air is
recovered and transferred to the supply air via a unique combination of active (heat pump) and passive (heat pipe) 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 it comes close to 100 %. This means that the need for heat supply 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
2emissions. During
summer the process is reversed and the supply air is cooled.
It is possible to add a heat exchanger to the refrigeration circuit. It enables utilisation of excess energy or waste energy created
by the cooling process, for example, for heating domestic hot water.
The unit is modularly designed according to individual wishes and needs, making it an extremely easy-to-install plug-and-play
solution. The unit can be controlled and monitored via our CTS602i control system.

Water after-heating element - integral
CO2-sensor
If you want the ventilation level to regulate in accordance with how many people are in the building, you
can order a unit with an integral CO2-sensor.
On the control panel you set the CO2-level you want. If this level is exceeded, ventilation will increase to
the set fan speed level.
Electrical after-heating element - integral
You will need to order an after-heating element if, for instance, you want to use the ventilation unit for
heating the building. The electrical after-heating element is installed in the ventilation unit at the factory.
The electrical after-heating element requires its own power supply.
Pressure-controlled filter alarm
As standard, the control system has a time-controlled filter alarm that can be set between 30 and 360 days.
If you want an accurate indication of when to change the filter, we recommend that you order a pres-
sure-controlled filter alarm. It displays the pressure drop over the filters in the CTS control system
regularly. You pre-set a final pressure drop in the control system, and an alarm will indicate when this
pressure drop has been reached and the filters need replacing.
Humidity sensor
If you want to regulate the fan speed level in accordance with the humidity level in the extract air, you
can order a unit with an integral humidity sensor.
The unit can change the fan speed level to low or high humidity level.
Handle with cylinder lock
If you want to be able to lock the service doors to the unit, you can purchase handles with a cylinder lock
and key.
Pressure control
The motor for the extract and/or supply air fan can be controlled by one or two pressure transmitters.
These should be mounted in the extract and/or supply air duct.
The standard version is delivered with pressure transmitters and a 5 m cable, including power supply.
Water after-heating element - integral
You will need to order an after-heating element if, for instance, you want to use the ventilation unit for
heating the building.
The water after-heating element is installed in the unit at the factory and it comes with a 3-way valve
and a Danfoss Actuator.

Water trap with ball
Heating cable
Internal heating cable inside the condensate drain
Vibration absorbers
Variable compressor
Water trap with ball
Ensures that condensate water can drain freely - also from compartments in the unit with negative
pressure. Should the water trap dry out, the ball will prevent air from being drawn into the system, and
condensate water will drain away freely.
Heating cable
If you install the ventilation unit outside the climate screen, it is important to protect the condensate
drain from frost.
Nilan A/S can supply an external heating cable that you run along the exterior of the condensate drain
before insulating it. This way you will have a frost free condensate drain that does not get blocked. The
heating cable has an integral thermostat that regulates the level of heating in accordance with the tem-
perature of the surroundings.
The cable is available in two lengths: 3 m or 5 m.
Internal heating cable inside the condensate drain
Internal heating cable for frost protection of the condensate drain running from the condensate tray
inside the unit to the water trap outside the unit.
Vibration absorbers
Vibration absorbers ensure that vibrations from the unit to the underlying surface are dampened
effectively. The vibration absorbers are placed under the unit.
Variable compressor
As standard, the ventilation unit is delivered with an on/off compressor.
The unit is also available with a variable compressor, which enables much better regulation of operation.
This means much lower energy consumption too.

Installation
Handling
Unwrapping
Transport after unwrapping
Unwrapping
The unit is delivered wrapped in foil. In order to protect the galvanized sheets on the unit from discolouration, immediately
remove the foil. You may consider covering the unit with tarpaulin until installation.
Transport after unwrapping
When you are going to position and install the unit, you can transport or move it in two different ways:
•
Lifting the unit from underneath with a pallet truck. Units with a pre-mounted foundation can be lifted directly with a pallet
truck - take care NOT to damage the base feet.
•
If you are lifting the unit using ropes/straps, the base angles must be more than 60°.If this is impossible due to a lack of space,
a lifting beam or similar must be used.
Lifting eye Min. 60 ° Lifting beam
ATTENTION
Visible transport damages must be reported immediately. Hidden transport damages must be reported within 7
days of delivery. When reporting transport damages, photo documentation is required.
Please see Incoterms 2020 for terms of delivery, warranties, limitation periods and compensation limits etc.

19
Installation
Positioning the unit
Positioning the unit
ATTENTION
Good clearance in front of the unit is recommended (see table below). When positioning the unit, you should
always consider future service and maintenance. It must be easy to replace filters and it must be possible to
replace fans or other components. There must be enough space to clean the unit easily. There must be space for
installing water traps in the condensate drains.
ATTENTION
The unit must be level to enable proper drainage from the condensate tray.
ATTENTION
The unit makes little noise and it produces 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
underlying surface, it is therefore recommended that you fit vibration absorbers under the unit. There should
be approx. 10 mm distance to other building components and to permanent fixtures.
