Continental Fan’s UDVL Upblast Roof Ventilators are designed to provide aerodynamically efficient performance and a low silhouette design. The ventilators are constructed with a heavy duty welded steel base, galvanized butterfly damper section, and a spark resistant cast aluminum airfoil axial impeller.
Greenheck’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.
Greenheck’s ICD series of Insulated Control Dampers have earned AMCA’s new certified rating of Energy Efficiency. This new test method, which is found in ANSI/AMCA standard 500D-12, assigns a damper a Thermal Efficiency Ratio (E) by comparing its thermal performance with the thermal performance of a standard reference damper.
Honeywell has launched a universal replacement Low/Medium Torque Actuator for fire and smoke dampers. The updated, UL555 and UL555S compliant actuator is designed to simplify the replacement process by offering new time-saving installation features in addition to reducing the number of models distributors need to stock.
The special nature of the occupants and activities in these facilities create special IAQ requirements, and the concerns only multiply when fire and smoke enter the picture.
The special nature of the occupants and activities in these facilities create special IAQ requirements, and the concerns only multiply when fire and smoke enters the picture. See how current codes and designs employ a combination of active and passive strategies, building on past approaches to minimize future incidents.
