Heavy Duty / Industrial Dampers

Heavy Duty / Industrial dampers are designed for use in industrial and severe duty applications.

Heavy duty flanged style frame dampers with various blade styles and pressure classes. Designed to control airflow and provide shut off in HVAC or industrial process control systems.

Heavy Duty / Industrial Dampers

Overview

Control Dampers

Control dampers are designed to control airflow and provide shutoff in HVAC or industrial process control systems.

  • Model HCD: Rectangular

    Model HCD: Rectangular

    Rectangular dampers are available in galvanized, painted steel, 304 stainless steel and 316 stainless steel with pressure and velocity capabilities up to 45 in. wg and 6000 fpm, respectively.


  • Model HCDR: Round

    Model HCDR: Round

    True round industrial dampers are available in galvanized, painted steel, 304 stainless steel and 316 stainless steel and pressure and velocity capabilities up to 20 in. wg and 6500 fpm, respectively.


Backdraft & Pressure Relief Dampers

  • Model HB: Rectangular

    Model HB: Rectangular

    A backdraft damper is an isolation damper allowing air in one direction only. Greenheck's HB damper series is designed to prevent backflow at static pressures and velocities up to 20 in. wg and 6400 fpm, respectively.


  • Model HPR: Rectangular

    Model HPR: Rectangular

    A pressure relief damper is a type of backdraft having an adjustable start-open pressure, which is capable of maintaining a relatively constant pressure at various airflows and closes upon a decrease in differential pressure. Greenheck's HPR damper series can be used as sa safety device or a controlling device. It is designed to provide pressure relief up to 6 in. wg and 3000 fpm, respectively.


  • Model HBS: Blast Dampers

    Model HBS: Blast Dampers

    A heavy duty blast suppression damper is design to protect against blasts and instantaneous pressure changes. The HBS damper series are constructed with heavy duty double flanged channel frame style backdraft dampers with a double thickness fabricated airfoil blades.

    Blast dampers can be used in the following applications:
    - Government buildings
    - Mining
    - oil and gas platforms
    - refineries
    - protection of ventilation systems.


  • Smoke Dampers

    Smoke Dampers

    Smoke damper is a heavy duty flanged frame style industrial control dampers UL555S qualified for use in engineered smoke control systems. Greenheck's HSD series is a Class I leakage with pressure and velocity capabilities up to 6 in. wg (1.5 kPa) and 3000 fpm (15.2 m/s), respectively.


  • Tunnel Transit

    Tunnel Transit

    A tunnel transit damper is a heavy duty damper designed to meet the rigorous environment of a transit tunnel and is especially qualified to withstand the stresses and pressures of such environments. The blades, frames, seals, and actuators are designed to meet the standards of NFPA-130, NFPA-502, UL-555S, and BS476; which are commonly found in tunnel transit specifications. Because of the demanding requirements of tunnel transit systems, the tunnel transit damper can be specifically designed to meet the requirements of every specification.


  • Model HTOD: Tornado Damper

    Model HTOD: Tornado Damper

    Tornado dampers are double flanged channel frame style backdraft dampers designed to protect against tornadoes and rapid pressure changes. Installed in ductwork, or wall mounted, near the exterior of a building, Greenheck tornado dampers allow for air movement (intake or exhaust) during normal weather conditins.
