About CTi Controltech

CTi Controltech takes great pride in providing the industrial, commercial and municipal markets in Northern California and Nevada with solutions for their process systems, combustion systems, industrial valves, valve automation and control systems since 1976.

CTi Controltech represents, or distributes for, the top manufacturers of valves, instrumentation, combustion equipment and boilers. CTi is an authorized service center for many of our manufacturers and we provide a wide array of off-premise and on-site services.



Art von Wronksi and Allan Zensius, both of whom had extensive burner/boiler and industrial controls experience, founded CTi Controltech in 1976. Together they built CTi to a regionally recognized leadership position in the combustion controls industry. Sadly, Art and Allan passed away in 2000 and 2001 respectively.

In May of 2002 George Constas purchased CTi. He has over 40 years of experience in the process control industry, including 22 years of company ownership.


Today CTi’s expertise has expanded beyond burner management and combustion control into other areas of process control in industries such as; Refining, Power (including renewable such as Geothermal and Solar), Food, Specialty Chemicals, Mining, Semi-conductor, and OEMs.

The companies employees consist of engineers, technicians, and sales/support personnel. Our facility is strategically based in San Ramon, CA.
