Ceiling-Mounted Dual-Flow Fresh Air Dehumidifier

Ceiling-mounted supply and extract air treatment with dehumidification.

Overview

The ceiling-mounted dual-flow fresh air dehumidifier combines supply and extract ventilation with moisture treatment in a concealed installation. It is intended for projects where incoming ventilation air must be considered together with the indoor humidity load.

Air is processed through the selected filtration and dehumidification arrangement before delivery. Moisture removed by a cooling-based process is collected as condensate and must be drained correctly. The supply and extract paths are coordinated with the room network and the required ventilation balance.

The ceiling position saves usable floor space but makes access and drainage especially important. Selection brings together airflow, entering-air temperature and humidity, required leaving conditions and the available ceiling clearance.

PRODUCT DETAILS

Product Features

Dual-flow ventilation arrangement

Supply and extract routes allow outdoor-air introduction and used-air removal to be coordinated. Their quantities are selected with the room use and the connected air-distribution system.

Integrated moisture treatment

The unit addresses humidity within the fresh-air treatment process. The required moisture-removal duty is based on entering conditions and ventilation demand, rather than airflow alone.

Cooling-based dehumidification

The catalogue explains moisture removal by cooling air below its dew point and collecting the condensed water. The actual cooling and temperature-control arrangement is confirmed for the selected unit.

Concealed ceiling format

Suspending the cabinet within a ceiling void helps keep walls and floors available. The installation still requires adequate structural support and room to reach internal components.

Filtration before distribution

The selected filter assembly treats incoming particles as part of the ventilation process. Filter access and resistance are considered when choosing the fan operating point.

Drainage and service provision

Condensate must have an unobstructed disposal route. Access for the drain pan, filters and treatment section is built into the ceiling layout so maintenance remains practical.

WHERE IT WORKS

Applications

Suitable for occupied spaces with a combined fresh-air and humidity-control requirement. The actual use depends on the selected model, available installation space and the indoor environmental targets.

Provide ventilation airflow, entering conditions, humidity target and drainage constraints. Dehumidification performance and final supply temperature are selected for the operating point; heat recovery is not assumed without a documented configuration.
