1 Way Lay-In Diffuser w/ Heat-Cool Changeover

Price DF1L-HC

The DF1L-HC displacement diffusers provide displacement ventilation cooling and linear custom flow slot heating in one unit.

Displacement airflow
DF1L-HC displacement diffusers are intended for mounting in a suspended ceiling installation for applications requiring both cooling and heating. The diffuser is designed to produce a vertical low velocity displacement air pattern when supplying cool air or an adjustable high velocity pattern when supplying heated air. The diffuser switches from cooling to heating mode or vice versa with an electric or thermal actuator. When the DF1L-HC is in cooling mode it discharges air evenly across the perforated face with minimal turbulence or induction of room air. The cool air falls slowly to the floor and gradually fills the space. When the DF1L-HC is in heating mode, it discharges air parallel to the face towards the perimeter with a high velocity jet. The superior air quality and low noise levels make the DF1L-HC suitable for offices, classrooms or any application where air quality demands are high, but there is minimal floor space and a requirement for both cooling and overhead heating.

Ceiling location
Air supply from above the space, integrated flush with a closed ceiling.

Adjustable airflow direction
Air discharge direction dependent upon whether in heating or cooling mode.

Thermal adjustment
Signal from BMS system operates a damper in the neck of the diffuser which determines operating mode

Electric adjustment
Integrated 24V AC Actuator.

Square face shape
Face sizes available at 600mm x 600mm or 1200mm x 600mm.

Perforated face pattern
Perforated steel front panel. Standard finish B12 White with special colours available

Metal Face
Powder coated perforated steel front panel. Standard finish B12 White.
