A Canadian Swedish Success Story

Lars, who has a Swedish background and has been active on the board of the Swedish Canadian Chamber of Commerce, was initially introduced to Klas Berglöf, the President and Founder of ClimaCheck Sweden AB, a Swedish company located in Nacka outside Stockholm, at the Swedish Trade Office in Toronto.

Through CanNord 2011 hosted by the Swedish Canadian Chamber of Commerce Darren, Colette and Lars were given the unique opportunity to meet with Klas on a more in depth basis to discuss business opportunities.

Renteknik’s experience developing markets for other energy related innovative technologies and their network of contacts in the HVAC and building industry provided the perfect opportunity to introduce ClimaCheck’s Energy Performance Analyzer into the Canadian Market.

Today Renteknik Group is the sole distributor of ClimaCheck in Canada and is also looking to expand into some states in the US in the near future.

The ClimaCheck Performance Analyzer, manufactured in Sweden, uses state-of-the-art methodology for “in field” energy performance analysis of all types and sizes of Air-Conditioning & Refrigeration Systems to help reduce peak cooling loads, increase energy efficiency, reduce operating costs and benefit the environment.

The ClimaCheck solution analyzes collected data and can immediately give a complete picture to the engineer of how the System is working and what adjustments or upgrades can be done to increase energy efficiency.  As part of Renteknik’s Energy Efficiency Solution, ClimaCheck is rapidly becoming Canada’s leading tool for commission, re-commission, trouble shooting and maintenance of Refrigeration Systems, Air-Conditioners, Chillers, Air Handling Units and Heat Pumps.

Through optimization using the ClimaCheck tools and processes Renteknik has typically found 10 – 30% savings in the electricity usage for Refrigeration / Cooling Systems usually without any capital expenditures.

In 2011 ClimaCheck was awarded the World Wildlife Fund Climate Solver Award for the technologies contribution to Green House Gas (GHG) reduction globally.  Renteknik has installed over 30 permanent ClimaCheck Systems in hospitals, ice-rinks, municipal buildings, condo buildings, hotels, supermarkets, data centres, and recreational facilities and is proud of its achievements in both energy savings and positive environmental impact.  This is a great success story for the partnering of ClimaCheck in Sweden and Renteknik in Canada.
