Ceiling-mounted treatment and distribution of outdoor air.

Overview

The ceiling-mounted fresh air handling unit treats and distributes outdoor air from within a suspended-ceiling installation. Its compact horizontal arrangement keeps the main equipment above the occupied room and connects to the building’s ductwork, water circuit and drainage system.

A fan draws air through filtration and a water coil before it is supplied to the room network. The selected coil can cool and dehumidify incoming air or provide heating from hot water. This is an air-treatment terminal connected to external utilities, rather than a self-contained cooling plant.

The D-series catalogue includes several airflow sizes and coil arrangements. Selection considers the outdoor-air duty, duct resistance and ceiling depth together, with clear access to the filter, fan, coil and condensate connection.

PRODUCT DETAILS

Product Features

Ceiling-mounted space use

The horizontal cabinet is suspended above the finished ceiling, reducing the amount of equipment occupying floor space. Ceiling structure and support points are checked for the selected unit.

Filtered outdoor-air treatment

A filter section removes incoming particulate contamination before the selected thermal treatment stages. The filter arrangement is coordinated with both air-quality needs and the available fan pressure.

Cooling and heating coils

Water-coil configurations are selected to meet the project duty. Cooling operation can also remove moisture when the coil conditions are suitable, with condensate collected and drained.

Ducted air distribution

The fan supplies air through connected ducts and room outlets. Airflow and external static pressure are chosen from the real system resistance rather than the nominal airflow alone.

Compact insulated construction

The ceiling series uses an integrated cabinet arrangement intended for concealed service spaces. Insulation and connection details are coordinated to limit unwanted heat exchange and surface condensation.

Practical installation access

The installation needs a level support arrangement, suitable condensate fall and a drain trap where required. Flexible connections and clear maintenance openings help prevent service loads from being carried by the casing.
