Vilter NH3 heat pumps in Ontario wastewater project - Cooling Post

CANADA: Copeland’s Vilter VQ95 single-screw ammonia industrial heat pumps have been selected to power what is claimed to be the world’s largest wastewater energy transfer (WET) facility in Ontario.

Markham District Energy’s facility at its Low Carbon Energy Centre in downtown Markham, extracts and converts energy from wastewater for sustainable heating and cooling.

The landmark project is expected to reduce carbon emissions from the production of thermal energy by more than 30,000 tonnes per year at the plant’s full capacity.

The WET facility differs from standard applications because it uses sewage wastewater as the primary heat source. The sewage enters at about 5ºC and is upgraded to usable heat at 95ºC.Additionally, the facility’s integration into an 8ft (2.4m) diameter underground sewage pipeline near the district energy building allows for large-scale, sustainable water heating while simultaneously providing cooling capacity.

Copeland’s industrial heat pumps are slated for delivery by mid-summer 2025 and to be fully operational by January 2026.
