DCS - MUCH MORE THAN JUST
HOT AIR!

Extraction engineers, Dust Control Systems Ltd, report growing interest in their upgrade and retrofitting services which include projects that dramatically reduce the running costs, together with schemes to turn woodwaste into energy.

One joinery manufacturer to benefit from the services provided by DCS is David Urquhart Joiners. The company, based in Portsoy on the north facing coast of Aberdeenshire, specialises in bespoke joinery for a growing customer base throughout Scotland. The firm’s modern, well-equipped workshops are divided into two main production cells – ‘Doorsets, Screens & Windows’ and ‘Staircases’. Custom made doorsets are produced for both internal and external application, with or without fire ratings and, within the staircases section, purpose-made stairs or standard specification stairs are manufactured. A skilled installation team is available for all types of projects ranging from home improvements to complete commercial fit-outs.

David Urquhart, who established the business in 1979, and continues to run the successful concern with the help of his son Wullie, says: “DCS Ltd installed our current dust extraction system in 2005 and we recently commissioned them to carry out two separate energy-saving projects – both of which have been a resounding success. The first project involved retrofitting a DCS Dynamic Drive System to our existing extraction system. We first learned what energy savings could be made with the Dynamic Drive System at the W8 exhibition and were sold on the idea. DCS successfully retrofitted the system without the need to replace any equipment or wiring. Selected woodworking machines have been fitted with dedicated auto-dampers which automatically vary the system’s volume as they open and close. The Dynamic Drive sensor detects the change in volume requirement and alters the fan speed to suit. This means that the main fan only uses the precise power required – and only when it’s needed. The latest project carried out for us by DCS was the installation of a heating system that is fuelled by wood dust, shavings and offcuts.”

For the wood burning heater project, DCS provided a new closed loop waste conveying system to handle waste produced by the existing extraction system. Waste is collected from the outlet of the modular filter unit and discharged into a mini silo unit which has a capacity of 12m³. Waste is then fed automatically to a 60kW woodwaste-fired air heater which has a built-on 450 litre feed hopper. The robust air heater is designed to burn all types of woodwaste and has an air capacity of 4000 m³/hr. A shredder is installed to handle over-size waste and offcuts, and the reduced waste is ducted into the main extraction system. Hot air is distributed to the workshop via an integral centrifugal fan and waste gases are fed through a multi-separator to remove heavy particles before being discharged through a fume fan and stainless steel flue.

Mr Urquhart adds: “DCS have done a great job for us. We are making huge savings on our electricity bills and we now have a warm, comfortable environment in which to work. And, it has all been achieved with an investment payback of less than two years. Everyone here is impressed with the way DCS managed the projects and with their prompt service response, particularly when you consider that it’s a round trip of 850 miles for their team.”
Melvyn Bathgate, sales director at Dust Control Systems, comments: “Although we still major on the design and installation of efficient dust extraction systems, energy saving technologies play an increasingly important role in our business. Of further benefit to our customers is the fact that most of these energy saving schemes can be financed with an interest free loan from the Carbon Trust.”
