Ventri Door Technologies may be a new name, but is backed with years of door experience.

Ventri was formed by amalgamating two powerhouses.

London Automatic Doors was acquired in 2021 by the Ardent group of companies to add more specialized expertise in door technologies and access control systems.
Zelus Doors of Stoney Creek and London Automatic Doors of London, Ontario. Combining Zelus' strengths in overhead doors and docks with London Automatic Doors' fortitude in automatic and overhead doors and access controls expanded the geographic coverage and product offering.

Zelus Material Handling, an Ardent owned Stoney Creek based business, also provided overhead door sales and service. Ventri is the combination of the strengths of each company leveraging experience, resources, and product offering.

Ventri embodies Ardent's culture and values, from authenticity and caring to passion for the work we do every single day.

Ventri is committed to delivering best-in-class products ranging from door solutions, docks, gates, and access control systems using advanced technologies.

We are part of the Ardent Group of Companies
