John Zink Company, LLC traces its roots to 1929 when John Steele Zink resigned his position at a gas company and began designing and selling a new burner that reduced fuel costs by burning natural gas more efficiently. The innovation and success of this product spread quickly throughout the industry and led to the company selling burners to refineries around the world. As time passed, other combustion related equipment, including flares and thermal oxidizers, was added to the product offering.
John Zink Company continues this legacy as a global leader in developing next-generation products, technologies and solutions to increase efficiency and enhance air quality through the clean, efficient combustion of fossil fuels. John Zink branded products include flares, flare gas recovery systems, burners, thermal oxidizers, and vapor control systems.
John Zink has more than 1,000 employees worldwide to serve our global customers. Our world headquarters is located in Tulsa, Oklahoma, with additional European operations in Luxembourg and sales and service offices strategically located worldwide.
John Zink's technologies are put to work every day by industry giants worldwide that refine oil, produce plastics, distribute fuels, transport energy, and manage waste. Our engineers literally wrote the book on combustion; The John Zink Combustion Handbook is an industry standard reference book. Since its publishing, this book has been a top seller of technical reference books.
John Zink Company has a team of world class researchers that uses a variety of approaches to develop patented technologies and continuously improves our portfolio of products. John Zink's Research and Development Test Center, located at our Tulsa headquarters, includes a wide range of state of the art testing capabilities. The next generation of ultra-low-emission combustion and environmental systems is engineered and exhaustively tested at industrial scale to measure performance under a wide a wide range of operating conditions. Cold flow capabilities are used to physically model industrial fluid flows. A team of Ph.D. engineers uses advanced computer hardware and computational fluid dynamic software to solve complicated turbulent fluid flow problems involving multiple step chemical reactions and non-linear heat transfer.
The world-renowned JOHN ZINK INSTITUTE sets new standards in knowledge-sharing through accredited, practical courses on process and boiler burners, process and biogas flares and vapor control technologies.
John Zink's world-class management systems are recognized and certified for meeting or exceeding industry standards in quality (ISO 9001), safety and health (OHSAS 18001), and the environment (ISO 14001).
