VAV-DH-B-10/20/30/40/50, Galvanized steel Construction. Voltage Rating: Single Phase / Three Phase VAV with Slip in Heater The reheat coils are factory fitted in to the corresponding VAV or CAV. It is designed so that the VAV or CAV followed by a heater battery are used in excessive humid places to avoid condensation of the equipment. Slip in heater-VAVs are widely used because it allows the duct work to be installed before the VAVs & heaters are available and simplifies the design. Furthermore, VAV with slip-in heaters may be installed without any special arrangements for their support.

DH- B-10, Galvanized steel / Stainless steel Construction. Voltage Rating:
Single Phase / Three Phase Models: DH-B-12; Flanged Heater (With Removable Heater Section) Flanged Heater consists of heater coils mounted in a flanged duct section. Frame dimensions are made to match exact duct dimensions. The frame is then attached directly to external flanges of the duct. All controls are mounted in the terminal box.

AEROSYS also manufactures multi-blade dynamic-rated-fire damper with 3V style blades for use in walls, floors, and partitions with fire-resistance ratings of 1½ hours and 3 hours. Dynamic-rated-fire dampers are used with HVAC systems that remain operational during a fire emergency. The product is tested and UL 555 classified with a fire resistance rating of 1½ hours or 3 hours for use in static as well as dynamic systems

AEROSYS manufactures Curtain type fire dampers in his fire and safety product range. The product is tested and classified as per UL555 standards by UL. These dampers are installed in ducts and air transfer openings of HVAC systems, designed to close upon the detection of fire. Fire dampers when closedinterrupt migratory airflow, close the passage of flame and maintain the integrity of the fire rated barrier. “Fire dampers are typically rated for 1½ or 3 hours’ fire resistance. As per IBC Chapter 7 and NFPA90A Chapter 5 “ 1½ rated damper is sufficient for wall or floors having a rating of less than 3 hours. If the wall or floor has a rating of 3 hours or more, a 3 hour rated damper is required for sufficient protection
