About Zesta

For over 50 years, Zesta has provided thermal solutions for the most demanding industrial heating applications.  Founded by G. Vince Eastman in 1968, Zesta established itself as a thermal systems provider by partnering with Watlow, now the world’s largest manufacturer of heaters, temperature sensors, and controllers.  Headquartered in Mississauga, Ontario, Zesta has a presence across Canada with warehouses in Québec, Alberta, and British Columbia.

To the present day, Zesta continues to be Watlow’s authorized distributor, serving the industry with leading-edge thermal innovations.  Watlow  manufactures industrial heaters, temperature sensors, controllers – all of the components of a thermal system.
