Granit Évolution is located in Courcelles, in the Eastern Townships region of Québec. The company specializes in manufacturing quartz and granite products such as countertops, stair treads and fireplace mantels.

To meet the high demand, the plant owners decided to expand during the slowest period of the year. But building in winter has its challenges, one of which is thawing the snow-covered ground.

“As part of our expansion, it was obvious we needed to install a temporary heating system. All our other heating options—electric, propane and oil—would have cost a fortune. We’re talking thousands of dollars per week, over several months,” explains Alain Goulet, CEO and co-owner, Granit Évolution.

Sequoia’s Blue Sky energy generator is a hot-water heating unit that runs on biomass fuel. Once installed, it can be connected to powerful Dragon Vert fan coils, placed strategically throughout the building.

“We’re under construction, so the ceiling isn’t insulated and the garage doors aren’t installed yet. What’s amazing is that air goes into the Dragon Vert at -15 °F but comes out at 100 °F,” he adds.

Sequoia’s Dragon Vert fan coils provide a comfortable and safe working environment. Energy generators and fan coils can be hooked up quickly and easily on construction sites. Once the work is done, the same equipment can be repositioned and used as the main heating system for the new building.

“We’ll recoup a big part of the cost of the biomass furnace just in temporary heating for our site, then use the same furnace to heat the plant. So it’s a win-win situation,” concludes Alain Goulet.
