The Mini Viking packaged small air handling units have been developed using feedback from installers through to the end user and benefit from tried and tested components; e.g. double skinned construction with plastisol outer panel, mineral wool insulation and galvanised steel inner panel.

This construction offers weather resistance and long life with a good thermal and acoustic performance. The materials can also be recycled.

Specification
Energy Considerations
Mini Viking Air Handling Units are designed with savings on potential energy consumption being a prime consideration. Low air resistance components are incorporated as standard, with high efficiency motors also available.

Model Range
Spanning a duty envelope of 0.1m³/s to 1.4m³/s, Mini Viking air handling units are available in eight direct drive and two belt drive sizes.

Standard units comprise of direct drive fan, filter, electric heater battery and built-in prepwired controls. Options available include belt drive as well as low pressure hot water, direct expansion and chilled water cooling coils.

Construction
Framework is anodised aluminium with airtight door seals and manual door catches which can be tool locked in position.

Double inlet, forward curved centrifugal fans provide the lowest noise levels with sufficient performance for ducted systems. Impellers and motor impeller assemblies are dynamically balanced to minimise vibration. Motors are further resiliently mounted.

The motors in VMD1L, VMD1M, VMD2L, VMD2M & VMD3L are conventionally mounted permanent capacitor type with sealed for life ball bearings. Protection is IP44 with Class F insulation (50º ambient max.).
VMD1H, VMD2H and VMD3H units have smooth and powerful outer rotor type motors. Note: all these direct driven fan/motor assemblies respond best to step transformer type speed control. This type of controller will maximise the service life of the motor.

Filters – Standard filters are EU4 pleated paper type 100mm deep. These have an efficiency equivalent to a standard grade bag filter and a better dust holding capacity than a fibre or foam filter. Special high grade bag filters can be supplied but they require an additional housing.

Hot Water Coils
Low pressure hot water coils employ copper tubes expanded into polyester coated aluminium fins. This provides a high efficiency with longer service life than many competitor’s coils.

Direct expansion and chilled water cooling coils are similar in construction, however they require an additional housing.

Electric heaters are sheathed tube type with low surface loading for long life. They include a manual reset high temperature cut-out and are mounted at the fan discharge to protect filters and motors from excess heat. Fan and heating controls are built in and wired internally, reducing site installation time to a minimum. A standard customer interface terminal box is common to all units and provides for various external remote items such as supply fan speed control, time clock, set point adjustment, PIR sensor and room or duct sensor. A power isolator is also provided. Outputs for extract fan (starter built-in), shut off damper and signal input from a fire alarm are also provided. N.B. An additional relay PCB will be required for use with an air quality sensor.

LPHW temperature control includes a proportional controller with a 0-10vDC output and a 3 port valve and motor (supplied loose). Set point range is 10-40ºC and the sensor should be positioned in the room on the return air duct.

Chilled water control can be achieved with the same system and an additional valve.

DX will require a relay PCB.

Electric heater temperature control is by thyristor. This method enables the sensor to be mounted down stream of the heater in the supply airflow and can hold ±1ºC of the chosen setpoint. A 0-10v cooling output signal is also available which can be used as above.

Frost electric duct heater is self contained and needs only a power supply. It is set to come on below -1ºC and off at +4ºC approx.

Inlet damper and motor come complete with weatherproof motor cover, needing only wiring into main terminal box.
