Profile: BSB Engineering Services Ltd. is a manufacturer of air, fire and smoke control products. We stock a wide range of products. Our BSB FSD-TD series of fire and smoke dampers is a device for use in heating, ventilation & air-conditioning systems, at fire boundaries to maintain compartmentation, and to protect a means of escape in case of fire. They can respond to a smoke alarm input, as well as having a failsafe thermal fuse. Our standard electro-mechanical control and monitoring system is ideal for systems with a small number of dampers in a single zone. It is also suitable for small to medium sized damper systems, or where a number of panels may be used to offer localized control in groups or zones. It provides a straightforward control panel with the most common features called for as standard. Due to differing site control and monitoring properties, damper actuators will be connected to site wiring when installed to provide the relevant functions. Our HD series multi-leaf volume control damper is designed for installation in systems where high air pressures and velocities are experienced. Combined with a robust construction, the damper is suitable for use on air handling units. We also enhance with testing services like fire tests, corrosion tests and air tests.
