2DFRE-GR-TRThermo-adjustable blade swirl diffuserDFRE-GR-TRThermo-adjustable swirl diffuser, model DFRE-GR-TR, provides anoptimum discharge in cooling (horizontal discharge) and heating(vertical discharge) enabling the diffuser to meet the requiredcomfort criteria by movement of its blades.DFRE-GR-TRThe diffuser is available in 6 sizes ranging from Ø160 mm to Ø 400mm in manually or thermo-adjustable versions. Increasinglystringent design requirements including higher supply flow rates,lower velocities, thermal gradients in the occupied zone and alsothe aesthetics have made swirl diffusers a better choice for airdiffusion.This is due to its high induction rate which can reduce velocities,airflow and obtain better thermal gradient conditions in the occupiedzone.Operation:The adjustable blade swirl diffuser allows the air dischargepattern to alter between horizontal and vertical by moving itsblades. This movement can be carried out manually or by a thermalelement which positions the blades depending on the supply airtemperature.The DFRE-GR-TR diffusers should ideally be mounted at heights inexcess of 3.5 m for supplying cooled, isothermal and heated air.This diffuser is an ideal choice for high ceilings applications in areassuch as airports, factories and public buildings due to its highaesthetic appeal, ease of installation, regulation, and high airvolume capacity.These diffusers can be incorporated in square panels for adaptioninto “lay in” tile replacement ceilings.DFRE-GR-Q-PR-TRMade of steel sheet, coated in white RAL 9010. Special finishesavailable upon request.The plenum box includes within the spigot a volume control damper,accessible from the side of the plenum, made of perforated sheet.If required plenum boxes can be provided with interior insulation.DFRE-GR-PR-TRThe thermoadjustable blade swirl diffuser integrated within aperforated plate has been developed for supply and extractapplications. The diffuser consists of a fixed perforated plate orhinged for easy access from the diffuser face, with athermoadjustable swirl diffuser on the rear.DFRE-GR-C-PR-TRManufactured from steel sheet, coated in white RAL 9010. Specialfinishes available upon request. The plenum box incorporates in thespigot a volume control damper, accessible from the side of theplenum, made of perforated sheet. If required, plenum boxes can beprovided with interior insulation.
