Our Gas-to-Air Heat Exchanger enhanced plant operations and reduced operating costs, while our Bag Filter was designed to avoid unscheduled production stoppages and facilitate maintenance.
Our Contract: Provide a complete upgrade to the air filtration system on the clinker cooler at the company’s original plant in St Mary’s, Ontario, built in 1912, and manage its installation.
Our Solution: We replaced the obsolete heat exchanger with one of our Gas-to-Air Heat Exchanger models in order to cool the gas flow from the clinker cooler, enhancing plant operations and reducing operating costs. We designed, built and installed one of our top-quality DPD-Model Bag Filters which we divided into four compartments, each of which can be separately closed with dampers in order to allow continued production even when one compartment requires maintenance. A new system of screw conveyors and flap valves was installed to discharge the dust collected in the Heat Exchanger and the Bag Filter into the existing dust transport system. A new I.D. Fan with an electric drive motor completed the installation. Finally, Redecam ensured the entire system was included into the main automation of the plant.
