After early technical studies, Gilles Lalonde starts his career as an industrial draftsman in transportation, naval construction, industrial ventilation and the first heat recovery systems. He works as a draftsman-designer for a workshop specialized in machining, robotics and pneumatic and hydraulic circuits development.The 70’s and the first energy crisis make a great impact on his choice of career. He decides to devote himself to steam recovery in 1981.

1984

Gilles designs the first SCCS^® (Steam-Condensate Closed System) and a series of related products, among which the vertical heat exchanger, which he installs at Agropur in Saint-Jean-sur-Richelieu. Other SCCS^® follow.

1986

Gilles starts Lalonde Systhermique inc. and implements many SCCS^®, including one at the Quebec Cartier Mining Company (now ArcelorMittal). In 1988, he aquires the Gestra distribution for Quebec and, a few years later, he becomes their distributor for Canada. Energy savings and steam condensate system optimization are his passion. Antoine Lavoisier’s famous quote: “Rien ne se perd, rien ne se crée, tout se transforme” applies especially well to steam. Gilles designs a SCCS^® without make-up water.

1999

the Gestra distribution division is sold. Gilles Lalonde concentrates his efforts on energy savings with more SCCS^® installations. After being schooled in specialized education, Éric Lalonde redirects his career and becomes a technician in building mechanicals. He works as a draftsman with a number of consulting engineering firms and as a building mechanicals technician at an automation and control distributor. He teaches AutoCAD in Repentigny and teaches energy savings to stationary machine mechanics in Lachine.

2016
