Exciting Announcement

We are excited to announce that Trimax, A Tesco Controls Company, is changing its name. Beginning November 1, 2022, our new company name is Tesco ControlsTESCO” for short.

In 2019 Trimax joined forces with Tesco Controls, the nation’s largest control systems integrator focused on the water/wastewater market. Although Trimax and Tesco Controls have been operating independently since then, staff have been working across both companies on water, energy and diverse automation projects. This collaboration has shown that both teams contribute unique capabilities and strengths that would make us stronger as one organization – and better position us to deliver more comprehensive, end-to-end power and process control solutions for our clients.
