Greenheck Adds New Model to Industrial Control Damper Line

November, 2025

Greenheck's HCDR line of round industrial control dampers has grown with the introduction of the HCDR-051. Designed to control airflow and provide tight shutoff in HVAC or industrial process control systems, the HCDR-051 is a light industrial model featuring a flanged-style frame with optional mounting holes for easy installation. Solid flanges are welded around the circular frame, providing a rigid base that supports the butterfly-style blade. The HCDR-051 can withstand velocities up to 3,000 fpm, pressures up to 6 in. wg, and a temperature range of -40°F to 250°F, and exceeds AMCA Class 1A with leakage under 1 cfm/ft2 at 1 in. wg. Available in sizes up to 24 inches in diameter, the HCDR-051 can be equipped with a variety of factory-installed actuators and optional features to meet specific application requirements.
