The Region of Waterloo, through its Consultants AECOM, has awarded Contract #4, in January 2012 to complete a $ 118 Million Project of the WATERLOO Wastewater Treatment Facility. Directrik Inc. will be supplying (2) DDI Heat Exchangers with Rectangular channels, and very wide gaps, capable of providing 5 MBTUH each.

Aecom has based their Heat Exchanger design on DDI’s

“Rectangular, Square, Cube”TM Heat Exchangers because of the Tight Space and NON plug requirements.

Several Heat Exchangers were considered including Tube and Tube Heat Exchangers for this project. As this was a fast track project, Drawing submittals, Delivery and Price played a major part in the Mechanical Contractors decision to go with DDI Heat Exchangers Inc.
