Kingly Street Office
Extract Fan & Duct Installation

BVS supplied and installed new boiler room ventilation in the plant room at the Kingly Street Office, London. Two fans were installed and connected to new ductwork, with both units wired into the existing mechanical distribution board and integrated into the building management system with automatic boiler shutdown controls.

Project Overview

The project involved the supply and installation of new boiler room ventilation at the Kingly Street office plant room. A boiler inlet supply fan and an extract fan were installed, each connected via new ductwork to the room's fresh air louvers. Both fans were wired into the existing mechanical distribution board and fitted with automatic controls integrated into the BMS.

What We Did

• Boiler Inlet Supply Fan: A fan rated at 0.752 m³/s was installed at a low level on the right-hand side of the plant room. Positioned under the existing fresh air louvers, the fan was connected to the window louver via new ductwork, which terminates with a bell mouth, ensuring consistent fresh air supply into the room.
• Extract Fan: The extract fan, rated at 0.361 m³/s, was installed at high level on the left-hand side of the plant room. The new ductwork connects this fan to the fresh air door louvers, effectively extracting air from the room and ensuring proper ventilation.

• Electrical Integration and Controls: Both fans were wired into the existing mechanical distribution board to utilise the current electrical infrastructure. Automatic controls were added to ensure the boiler(s) will automatically shut down if either fan fails to operate. These controls were integrated into the building management system (BMS) to provide seamless monitoring and efficient operation.
