Recommendation
As there is a risk of condensate due to the location of the airways, we often recommend the purchase of accessory V100CFCONTUBE (a condensation drain and fitting for the exhaust side).

The VEX100CF counter flow heat exchanger is made of aluminium. It is designed to ensure the ratio of heat recovery and pressure loss is at an optimum, i.e.

extremely high temperature efficiency is achieved at low levels of energy consumption.

    • Efficiency level without condensation: 80–85 %
    • Efficiency with condensation: Up to 94 %

The combination of modern EC motors and the EXHAUSTO motor controller delivers extremely low energy consumption and with the EXstream impeller, a high output is achieved.

An energy label that states the energy class of the unit in relation to defined operating conditions is available via our product calculation programs.

The easily accessible connection box with built-in isolator switch and control fuses ensures easy access for connection and adjustment.

The panel filters are easy to replace and can be ordered as filter class Coarse 85% (M5) or ePM_1 55% (F7) in acc. with EN779.

The VEX100CF range is supplied with an integrated heating coil, heated either by water or electricity

Mounting base is an accessory for VEX140-150-160 and standard on VEX170.

The mounting base is equipped with feet that have an adjustable height of 130 - 160 mm.

The motor sections are mounted in vibration dampers, which reduces noise in the ducts and eliminates the need to fit flexible connections between the unit and the duct system.

The motor sections can be extracted for easier servicing.

The motors are of type EC and are extremely efficient. They comply with the requirements of the Ecodesign Directive.

With some projects, limited space means that internal transport of the air handling unit is difficult or impossible. This is why the VEX100CF is available as a split version. It means that the air handling unit can be assembled and tested at the factory as normal – just without sealant. The air handling unit can therefore be easily taken apart at the installation site, transported as single sections, assembled, sealed and commissioned.

The VEX100CF is designed with a de-icing bypass. If there is a risk of icing, then a certain amount of outdoor air will bypass the heat exchanger and go directly to the after heating coil. This increases the demands on the heating coil’s output. However, it avoids a costly preheating coil. The drawing below is an example of a de-icing situation, where 20% of outdoor air is directed through the bypass damper.

Heating coil and de-icing function:

The de-icing situation is shown above, a heating coil is included here. This is completely necessary, in order for the de-icing function to function correctly. Without the heating coil, the de-icing process would cause the temperature of the supply air to fall, and sooner or later the VEX unit would stop because of icing

The heat exchanger has two forms of frost protection: temperature-controlled or pressure-controlled. The actual de-icing can take place in several ways, depending on whether an after heating coil has been fitted.

The control system has temperature-controlled frost protection as standard. It is an inexpensive solution and provides sufficient frost-protection in some situations.

A temperature sensor is fitted inside the heat exchanger and if the temperature falls to a pre-set value, de-icing begins. This temperature level is factory set to 0 °C but it can also be changed to a new value via the control system.

Temperature-controlled frost protection triggers the de-icing process even if there is no ice in the heat exchanger.

The control system monitors the actual airflow and also the pressure drop across the heat exchanger. If ice forms in the heat exchanger, the pressure drop across the heat exchanger will increase and when it exceeds a pre-set value, de-icing begins.

Pressure-controlled frost protection only starts de-icing when ice has actually formed, regardless of whether there are sub-zero temperatures.
