Trolex and the newly acquired Zonex Systems, with a history that also goes back to the ‘60s, continue to manufacture zone dampers for original equipment manufacturers
Trolex Corporation is celebrating its 60th anniversary this month on the heels of an acquisition that increases its market share in the commercial zoning market.
The non-corrugated, "stock" spiral duct can be used for commercial HVAC applications up to -1.0” WG through 42” diameter, up to -2.0” WG through 34” diameter, and up to -4.0” WG through 16” diameter.
By replacing conventional hangers, this system provides increased flexibility in duct layout and simplifies installation, thereby reducing labor and material costs.
