VPM 240

VPM 240 comprises highly efficient heat recovery units with cooling facility. The units are specially developed for use in commercial buildings which require air renewal up to 2,400 m³/hour.

A VPM unit removes the hot, humid air from the building and injects temperate air. The energy in the extract air is recovered and transferred to the incoming air via a unique combination of active (heat pump) and passive (heat pipe) heat recovery. The high efficiency of the VPM range is due to the unique construction, which combines the best of two technologies. The technology improves energy efficiency so that it is close to 100 %. This means that the need for the supply of heat during the cold months of the year is reduced to a minimum, and significant savings are made on the building's energy consumption and CO2 emissions. During the summer the process is reversed so that the incoming air is cooled.

The plug’n’play solution is modular and can be configured to match individual customer wishes and requirements. This makes the range extremely simple to install. The unit is monitored and controlled by our CTS 602i or 6000 control panel.

VPM 120-560 is a series of ventilation units with heat recovery useful for ventilation of schools, offices and business premises with a ventilation requirement of up to 6,600 m3/h, and where cooling may also be required.

Heat recovery takes place via a heat pump that recovers up to 100% of the heat in the extracted air. The heat pump has a reversible cooling circuit, which means that the unit can also provide cooling. 

If the unit is dimensioned for cooling requirements, in most cases the heat pump will be able to provide enough heating to make a supplementary heating element superfluous.

CTS 6000 control

For online monitoring and control of the unit, Nilan’s CTS 6000 Automatic control can be used (See description of the automatic control on pages 28 and 29).

LON/Modbus card
CTS 6000 automatic control can be connected to an external building management system with LON or Modbus communication. This card is an accessory to the CTS 6000 automatic control.

VTZ compressor

 

VTZ is a frequency-controlled compressor with constant, stable regulation. The compressor adapts its operation to the cooling or heating requirement, and will thereby achieve a high COP value,
and low energy consumption.

 

The VTZ compressor can only be used with the CTS 6000 automatic
control.

 

Shut-off damper

Damper for external installation is provided in a set of two, with attached servomotor.

  • For CTS 602 a 230-V servomotor is included.
  • For CTS 6000 a 24-V servomotor is included.

 

Heating elements

 

A heating element can raise the supply air temperature to the required level VPM 120-560 is available with integrated waterheating or electrical residual heating element.

 

Both automatic controls can also regulate external heating elements.

 

Pressure regulated filter alarm

Measures the pressure drop across the filter and alerts when the filter is to be replaced.

Heating cable

To protect the condensation outlet against frost, a 3 metre-long self-regulating heating cable can be ordered.

 

Water trap

The water trap makes sure that condensate water runs freely from the unit.

 

Top cover

If the unit is going to be installed outside, it is possible to order a top cover which protects the unit against rain and snow.

 

Pressure transmitter

The extraction and/or supply fan can be operated with the aid of one or two pressure transmitters.

 

CO2-sensor – CTS 602 control

With a CO2-sensor installed, the ventilation speed can be pre-programmed with CTS 602 to run at a higher ventilation steps when CO2 reaches high level in the extract air. CO2-level is programmable (expansion PCB required).

Capacity

Max Pa capacity of standard unit, Pt,ext as a function of qv, with regard to SFP-values.

SFP-values according to EN13414-7 for a standard unit with ISO ePM10 >60% (M5) & ISO ePM1 50% (F7) filters an no heating element.

Attention! The SFP values are measured and stated as a total value for both fans.

Sound data

Sound data for qV = 2,400 m3/h and Pt, ext = 250 Pa according to EN 9614-2 for surfaces and EN 5136 for ducts.

Sound output level LWA drops with falling air volume and falling back pressure.

Sound output level LpA at a given distance will depend on acoustic conditions in the place of installation.

COP (air/air)

Heat effect factor COP [-] supply air as function of outdoor temperature [°C] and volume flow qv [m3/h].

According to EN14511, extract air = 21 °C.

Heat effect (supply air)

Heat effect Qc [W] as a function of qv 2,400 m3/h and outdoor air temperature [°C].

According to EN 14511, extract air = 21 °C

Cooling effect

Supply air temperature [°C] as a function of outdoor air temperature [°C] and volume flow qv 2,400 m3/h balanced flow.

Extract air temperature = 24 °C
