Peerless Emissions Control

Peerless Emissions Control


Helping customers meet environmental compliance through industry-leading combustion and post-combustion emissions control technologies reducing NOx, CO, VOC, NH3, PM and other government-regulated requirements.

As part of the energy transition, existing utilities are repowering combined-cycle power plants to provide their customers with safer, cleaner, more efficient and reliable power. Emissions compliance is critical, and Peerless has the technical experts and latest technologies to ensure compliance.

Founded nearly a century ago, the Peerless legacy of providing safe, efficient and clean technologies began when our founder, Don A. Seller's, invented the first natural gas odorizer saving countless lives with safer natural gas leak detection.

Peerless continued to focus on energy efficiency in the 1970s with other inventions, including patented vane separators which are still a critical design solution for our portfolio of Peerless Separation and Filtration technologies.

In the late 1980s, Peerless expanded its focus to help protect our environment with the launch of our Selective Catalytic Reduction (SCR) division. With the acquisition of CCA Combustion Systems in 2014, Peerless further diversified clean, safe emissions and combustion solutions to broader and diversified end markets.

Whether it's a hospital, university, pharmaceutical facility, pulp-and-paper plant, industrial process, petrochemical, chemical, refinery or power generation, Peerless continues to help customers meet ever-changing, stringent compliance requirements.

As part of the CECO Environmental family, Peerless offers integrated technologies and solutions for its customers, enabling a cleaner and safer environment. Headquartered in the United States, with additional offices in the UK, Dubai, Shanghai, and Singapore, Peerless serves customers in all time zones and locations around the globe.

Power – Fossil (Coal, Gas, Petroleum)

Fossil energy sources, including oil, coal and natural gas, are non-renewable resources that formed when prehistoric plants and animals died and were gradually buried by layers of rock. Today, fossil fuel industries drill or mine for these energy sources, burn them to produce electricity or refine them for use as fuel for heating or transportation.
