HEE-Duall
Corrosion-resistant scrubbers, fans, and ducting
Founded in 1973 as Harrington Environmental Engineering (HEE), HEE-Duall has built a reputation for engineering reliable solutions that perform in the harshest industrial and municipal environments. Following our merger with Duall and integration into CECO Environmental in 2013, we expanded from fiberglass vessels into advanced thermoplastic systems. Today, HEE-Duall specializes in designing and manufacturing corrosion-resistant scrubbers, fans, and ducting that effectively control corrosive gases, volatile organic compounds (VOCs), odors, and hazardous pollutants. Our systems are trusted worldwide for delivering clean air, compliance with strict environmental regulations, and long-term operational efficiency.
