Industrial Blast Dampers protect against pressure changes.
2015-10-09 14:31:09| Industrial Newsroom - All News for Today
Qualified to pressures as high as 15 psi, Models HBS-430 and HBS-431 protect against blasts and instantaneous pressure changes. These heavy-duty, double-flanged, channel frame-style dampers feature double thickness fabricated airfoil blades and cover applications in UFC and GSA codes and standards, including Charge Weight I at 82 ft. Areas of use include government buildings, mining, oil and gas platforms, refineries, and protection of ventilation systems.

Video: Integral Tracking for the Hot Air Dampers
2015-09-21 22:09:00| Chemical Processing
Should a hot air damper be driven either fully open or fully closed, integral tracking must be activated in either the hot air pressure controller or the bag house inlet temperature controller. The issues are similar to those for output tracking presented in a previous video. To access the entire video series from Cecil Smith, visit our video page. Cecil Smith is president of Cecil L.

Video: Controls for Hot Air Dampers in Alternate Control Configuration
2015-09-17 20:57:00| Chemical Processing
This video proposes controls for the hot air pressure and the bag house inlet temperature. Interaction is a major concern. Opening either hot air damper decreases the hot air pressure. Opening the hot air damper to bag house inlet increases the bag house inlet temperature. Opening the hot air damper to scrubber duct inlet alters the distribution of hot air so as to decrease the bag house inlet temperature.
