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.

Overview

Control Dampers

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

  • 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

    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.


  • Model IVDE: Inlet Vane

    Typically mounted to the inlet flange of an industrial fan to more efficiently control the amount of airflow entering the fan. Available with manual, electric, or pneumatic actuators. Maximum operating temperature is 200° F.


Backdraft & Pressure Relief Dampers

  • 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

    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.


  • 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

    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.
