What Tempeff does
Tempeff is a Winnipeg, Manitoba-based manufacturer of energy recovery ventilation (ERV) and heat recovery ventilation (HRV) equipment for commercial, industrial, institutional, and high-performance residential buildings across North America. The company's core technology is its proprietary DualCore® system, which uses two alternating heat exchangers to prevent frost buildup and deliver 80–97% heat recovery efficiency with continuous fresh-air supply at sustained outdoor temperatures as low as -40°C — outperforming conventional single-core HRVs that require efficiency-robbing defrost cycles. The product portfolio includes DualCore® and DualCorePlus™ platforms, the RGSP-K unit, the RG/RGL/RGN ventilator series, and complementary components (energy recovery wheels, heat pipes, fixed plates, air handling units).
Tempeff sells through a direct sales model supported by a network of regional engineering and sales advisor firms covering every Canadian province/territory and all 50 U.S. states. Customers are largely project-based enterprise buyers specifying into LEED Platinum, Passive House (PHI/PHIUS+), and northern/remote-climate applications, with unit pricing positioned at a roughly 5x premium versus commodity HRVs (~$5,000 CAD vs ~$1,000). Reference installations include Saint Martin's University (Cebula Hall — highest-scoring LEED building in the Western Hemisphere), Montreal Planetarium, Great-West Life (Balmoral), Doig River First Nation Cultural Centre, Living Libations, and Hebron Heights Senior Housing. DualCore technology has been independently validated by the National Research Council Canada in climactic chamber testing at -40°C and at the Canadian High Arctic Research Station. Tempeff operates as a subsidiary of the NIBE Group, a Swedish-based global conglomerate of 120+ companies and 18,700 employees, which provides global distribution reach and brand credibility while the company maintains specialized focus on the North American market.
