VEX300T

VEX300T is a range of compact air handling units in which all ducts exit the top of the unit. Water is also connected to the cooling/heating surface placed in the top of the air handling unit, just as the condensation outlet is connected on the front of the unit. Therefore, VEX300T can be placed closely to other technical equipment, since the end walls do not need to be accessed for service.

The range consists of 5 sizes, with an option for the EXact2 control system or prepared for a third party control system.

VEX300T has been construced with integral heating or cooling coils, which reduces the installation costs. It is also possible to choose filtration of the supply air.

The design is optimised for compactness, temperature efficiency, airflow and energy consumption. Despite being very compact in size, the unit is easy to service, e.g. for filter change, cleaning, etc.

Functioning principles

The VEX 300T brings fresh, filtered air into the building and recovers heat from exhaust air using its high-efficiency heat exchanger. The incoming air can be heated and/or cooled using a comprehensive range of coils.

Cabinets are made from Aluzinc® AZ185 class C4 in accordance with EN/ISO12944-2 and insulated with 50 mm mineral wool. This results in low noise emissions to the surrounding environment/installation room.

The panel design minimises the formation of thermal bridges in the unit.

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