Dectron Internationale (DECT) was officially launched as a public corporation and has been trading in NASDAQ since fall of 1998 to March 2007 and the TSX since May 2005. The corporation originates from a consortium of private companies in the Indoor Air Quality industry.

Dectron was founded in 1976 with the objective of preventing structural damage caused by high levels of humidity in indoor pools. In this pursuit, Dectron pioneers the indoor pool dehumidification market with the introduction of the DRY-O-TRON®, a mechanical dehumidification system that uses a revolutionary energy saving feature that controls humidity levels while helping maintain comfortable temperature levels of the pool’s water as well as the air inside the building.

In 1995, Ness Lakdawala, (President and C.E.O) acquires Dectron to form the Dectron Group, a diversified group of companies with vertical integration synergies. The group includes RefPlus, a manufacturer of commercial refrigeration equipment supplying the food industry, and Thermoplus Air, a manufacturer of specialized air conditioning and heating solutions supplying commercial and industrial sectors.

In 1998, Dectron Internationale begins trading in NASDAQ. Soon after the IPO, Dectron Internationale acquires Circul-Aire, a supplier of air purification technologies to the oil, mining and paper industries, and PM Wright Limited, a manufacturer of customized electrical heaters supplying other manufacturers mainly in the transportation industry.

In 1999, the company acquires IPAC Inc, a manufacturer of precision air conditioning equipment, providing solutions for computer and control rooms for the telecommunications industry.
In 2000, the company introduces a revolutionary concept: designer indoor air® (dia), allowing for the engineering, specification, design and manufacturing of solutions to address multi-spectrum indoor air problems as a single source supplier.

In 2002, the company acquires the intellectual assets of International Water Makers, a supplier of water generation equipment using a patented breakthrough process to generate water from air. In December of the same year Dectron Internationale divests PM Wright, a subsidiary of Circul-Aire .

In 2003, the company acquires Tranzmetal; an ISO certified manufacturer of Customized Precision Sheet Metal Products.

In 2005, Dectron Internationale obtains ISO 9001:2000 certifications for Dectron Inc and  Circul-Aire and in 2007, adds RefPlus to their certification.

In the years to come Dectron Internationale will continue to leverage its unique ability to provide indoor air quality solutions that combine state-of-the-art particulate filtration and chemically engineered gas-phase filtration media for toxic air removal, together with very specialized energy recycling, humidity and temperature control systems. The “designer indoor air®” concept will continue to ensure single-source responsibility. For the engineers, architects, general contractors and consumers alike this means a guarantee of the highest quality in design and fabrication of solutions to meet the most stringent requirements for safe and comfortable indoor air.
