HSC-FD Fixed Helical Swirl Diffuser

 

The SMARTEMP HSC-FD is the highest capacity and highest performing fixed vane VAV swirl diffuser. The SMARTEMP Fixed Helical Swirl Diffuser, type HSC-FD, discharges the supply air with high induction swirl in a fixed radial pattern, producing horizontal discharge into the space. It may be ceiling mounted or freely suspended.

20 off-set radial swirl vanes with helical twist and cambered leading edges increase both the maximum airflow rate and the VAV operating range, whilst reducing noise and minimum permissible supply air temperature.

Nominal Neck Sizes:

DN250, DN355, DN500
 

Discharge height: 

2.4 – 4.5 m

Features

 

  • Nominal neck sizes: DN250, DN355, DN500
  • Maximum possible ^T when cooling is -16 K.
  • Suitable for VAV with turndown to 25%.
  • Square or round face available.
  • Aesthetic matches HSC-AD.
  • High capacity, high inductive discharge for high comfort.
  • Discharge height: 2.4 – 4.5m.
  • The world's highest performing, high volume flow, fixed vane VAV swirl diffuser
  • High capacity swirl diffuser with high induction, fixed horizontal discharge pattern from swirl vanes flush with diffuser face, optionally screened by perforated cover plate. Unique helical twist vane design provides high airflow capacity, and allows low-temperature VAV (Tsupply ≥ 5 °C) with turndown to 25%.  
  • May be mounted flush with ceiling or free-hanging.

20 radially off-set swirl vanes increase induction. Swirl vanes with helical twist reduce pressure drop and increase capacity. Low pressure drop reduces fan energy. High capacity airflow reduces archi

 

  • 20 radially off-set swirl vanes increase induction.
  • Swirl vanes with helical twist reduce pressure drop and increase capacity.
  • Low pressure drop reduces fan energy.
  • High capacity airflow reduces architectural impact.
  • Flush face enhances aesthetics.
