Credibility
Proven control systems delivered to refiners across five continents, backed by more than a half-century of field-verified performance.
From FCC main air blowers to hydrogen recycle compressors and utility steam turbines, refiners trust our control systems on the machines a unit cannot run without. With thousands of installations and millions of collective operating hours on critical turbomachinery, our solutions help define practice rather than just meet it. Programmed to IEC 61131-3 on commercial platforms, they give customers long-term flexibility and ownership, full access to configuration, calibration, and application logic to operate, maintain, and expand between turnarounds.
Applications
Anti-surge, capacity, and driver control for the axial and centrifugal machines the fluid catalytic cracker depends on.
Fast, deterministic surge protection for centrifugal and axial compressors under variable inlet conditions, including startup, shutdown, and upset events.
Integrated fire water pump control with automatic start on demand, test sequencing, and status reporting, engineered to support NFPA 20 and listed fire pump controllers.
Reliable hydrogen recycle and makeup compression for hydrotreating and hydrocracking, with anti-surge and load control.
Precision pressure and flow management on high-pressure charge and product pumps, with variable- and fixed-speed drivers.
Reliable hydrogen recycle and makeup compression for hydrotreating and hydrocracking, with anti-surge and load control.
Speed governing, valve management, and overspeed protection for steam-turbine-driven compressors and pumps.
Boiler, steam header, and generator load-sharing control for the refinery utility block and on-site cogeneration.
Speed governing, valve management, and overspeed protection for steam-turbine-driven compressors and pumps.
Loop control and coordination for process pressure, flow, temperature, and level integrated with the rotating-equipment control layer.
Design, fabrication, and certification of control panels for hazardous areas (UL, ATEX, and project-specific), supporting NEC 500 Class/Division and NEC 505/IEC/ATEX Zone classifications.
Loop control and coordination for process pressure, flow, temperature, and level integrated with the rotating-equipment control layer.
Where We Work
Engineering Depth
Engineering in New Orleans (HQ), Houston, and the UK; projects executed worldwide to local codes and area classifications (IECEx, ATEX, NEC 500/505) with protective functions engineered to support SIL 2/3 where the project requires.
Trusted Worldwide
Active installations at refineries across North America, South America, Europe, the Middle East, and Asia-Pacific.
Independent control for every turbine class.
Anti-surge, loadshare, performance, and capacity control.

A MESSAGE FROM JOHN KAZOUR, CEO
To our customers and partners,
For more than 50 years, our team has helped customers keep critical operations running. We built our reputation as Petrotech by taking responsibility for control systems on important rotating machinery.
As more industries came to us with similar challenges across power generation, compression, and hydro applications, our engineering team kept finding ways to solve them. Eventually, the business outgrew the Petrotech name.
We are entering our next chapter as Innova Technologies. The new name reflects the full scope of our work as a rotating machinery control systems specialist. We engineer controls around the machine, deliver complete projects from design through commissioning, and provide support that stays with the problem until it is solved.
Our name is changing, but the people, engineering experience, and commitment behind the work continue. Our responsibility to active projects and installed systems carries forward under the Innova Technologies name. Your current contacts remain the right place to start, and we will communicate directly if an administrative record requires an update.
We appreciate the trust you have placed in us over the decades, and we look forward to continuing that work as Innova Technologies.
CEO, Innova Technologies
