Plastics Regrind - Used equipment

Known Issues:

• 6 Regrind cells

• Not all cells are used at the same time

• Some cells are used much more than others, due to size

• Need to reduce electrical consumption

• Need to eliminate Heat loss in the winter months

• January indoor temps 70 degrees F and Outdoor air temps as low as -50 degrees F

• Budget would not allow for New Equipment

Provided Solutions:

• Located a used collector and fan that met air volume and static pressure system requirements. Donaldson Torit Model DFT 3-24.

• Located aftermarket silencer (80 dBA) to reduce noise levels when returning air back into building.

• Provided heated solenoid enclosure to keep valves from freezing in the winter months.

• Provided Delta P Plus filter cleaning control (digital photohelic gauge) to manage filter cleaning and provide alarm (strobe) when filters are no longer viable.

• Built custom inlet plenum to allow for multiple duct connections to dust collector.

• Connected each regrind cell to collector independently to allow for independent use.

• Built custom control cabinet with VFD and air flow control system to provide air only to cells that are in use.

• Used compressed air driven automatic blast gates to open/close duct lines independently.

• Used clamp together duct work to allow for mobility.

• Returnede cleaned air into the building to limit winter heat loss and eliminate the need for make up air.
