According to Det-Tronics, its SmokeWatch™ U5015 uses advanced photoelectric smoke detection technology not generally available in an explosion-proof housing. The detector is rated for Class 1 Division 1, 2, and Zone 1 environments found in industrial applications. Used with the Q5016 Duct Mount Accessory, the detector can be installed on ductwork to meet NFPA 90A requirements for AHUs of more than 2,000 cfm.
In last November’s Back2Basics, I created a test for the readers based on the idea that the patient room design was similar to a pharmaceutical cleanroom, with an air lock for people to enter and leave the room.
A new survey from the Building Commissioning Association (BCA) found that an overwhelming majority of engineers and other building professionals believe that duct leakage is a significant cause of energy loss in most commercial buildings today.
When it comes to ductwork for VAV systems, could the shortest path to better air handling cost and efficiencies be round (or spiral)? Aided by static regain and streamlined installation, here’s the case for no more corners.
