Financially viable Green Cooling - A new energy-efficient and water-based cooling technology

The technology provides cooling by using heat and little electricity. Its strength lies in its ability to utilize low-grade heat for the expensive and vital process of cooling, reducing both cooling costs and GHG emissions at the same time.

Today’s standard for cooling our buildings and facilities relies upon a century-old cooling technology called "Vapour Compression Cooling". It consists of a mechanical compressor that consumes significant amounts of electricity, which makes these systems costly to operate. It also uses synthetic refrigerants that tend to leak at a rate of 7-10% annually and are over 1000 times more detrimental in terms of global warming than CO2. Enersion has solved these problems by introducing a new cooling technology that uses low-grade heat (~60 C) instead of electricity as the energy input, and water as a refrigerant in a vacuum-sealed system. The Enersion technology uses 70% less electricity without any harmful refrigerants. By replacing the mechanical compression with thermal compression, this innovative system reaches a coefficient of performance exceeding 23 for electrical performance and 0.6 for thermal performance.

Key features

  • 70% reduction of electricity consumption compared to conventional solution - representing up to 830kg of CO2e per year for one ton of cooling
  • No harmful refrigerant or emissions
  • For a chiller in Toronto this amounts to 830 kg of CO2e per year for just one ton of coolin


  • Rate of return between 2-3 years
  • Priced competitively compared to current technology
  • Reduces by 68% cooling costs compared to a conventional cooling tower
  • Reduces by 77% costs compared to a conventional chiller
