Greenheck-041414-body.jpgGreenheck’s industrial dampers are heavy-duty, flanged-style frame dampers with various blade styles and pressure classes designed to control airflow and provide shut-off in HVAC and industrial process control systems. Built under an ISO9001-2008 Quality Assurance Program, Greenheck says its industrial dampers offer heavy-duty options for air control, shut-off, balancing, and isolation for higher pressures, temperatures, and airflows than commercial grade dampers. Ideal for nuclear, tunnel, bio lab, and power generation applications, Greenheck’s complete line of industrial dampers includes control, backdraft and pressure relief, UL rated smoke, tunnel transit, blast, tornado, and bubble tight dampers.
