Brunel Construction Centre, Huddersfield, part of Kirklees College, specialises in construction-based courses such as plumbing, bricklaying, carpentry and joinery. Kirklees College’s woodwork department inherited an impressive array of industrial machinery from the previous tenants, and has since invested heavily, installing new woodworking equipment including spindle moulders, planers, and a state-of-the-art five-head moulder.
To further improve the facility, Extraction Solutions was invited to survey the workshop, with the intention of replacing its aging extraction unit with a new, energy-efficient, ATEX-compliant installation. The existing system was installed before the ATEX regulations came into law in 2003, and the duct system has since been heavily modified, resulting in low efficiency and reduced dust capture.
“After a discussion with Daniel and Peter from Kirklees College, it was clear that only a percentage of the machines would operate at any one time, with students intermittently using machines throughout their projects,” explains ESL’s design engineer, James Parkes.
“By correctly sizing the duct system it enables us to use dampers to select between two or more machines, which has the added benefit of reducing the plant size. We coupled the fan with a smart inverter which constantly optimises the fan speed depending on the required duty.”
During normal operation this could save the college over 7kW per hour, greatly reducing running costs and offering flexibility throughout the system.
