Systems for heat recovery in Canada

When Toronto Hospital was looking for a heat exchange system to cover 90% of their heating and cooling needs with renewable energy, they chose Aliaxis as a partner to best capture the thermal energy in underground sewer wastewater.

The challenge was efficiently accessing the wastewater used in the heat exchangers from so far deep underground. Normally this movement requires significant energy to exchange and the odours emitted would have been intolerable.

We therefore worked closely with the engineer for over a year to provide a customised solution based on our Vortex™ Flow system, eliminating the need for chemical treatments, biofilters and air scrubbers, demonstrating how our technology can drive sustainable, low-maintenance operations in large-scale buildings and greatly reduce greenhouse gas emissions.
