Launch of Annexair aluminum framing casing systems
We were the first in the industry to build HVAC casings with rigid aluminum framing systems, reducing overall unit weight by 30% versus steel casings and expanding unit lifetime. Superior rigidity, reduction of leaks and overall increase in unit performance were valuable advantages.
Relocation to a modern, larger facility with a total area of 30,000 sq. ft.
More organized, more staff and sales of $500K that year.

Construction of our climate chamber lab and our showroom in the Ecoref building
Annexair has 2 buildings now: the main plant at 95,000 sq.ft and Ecoref building (30,000 sq. ft.). For our R&D needs, we built our 1st climate chamber lab in the Ecoref building. At the time, this 30 ft. x 70 ft. x 20 ft. height lab was the most high-tech and sophisticated lab in North America. A long period of simulating numerous weather conditions was used mainly to optimize Annexair unit’s performance, validate supplier’s components and maximize unit performances.
