Jeremias might have the world’s largest capacity laboratory for testing chimney and venting systems.

Jeremias Inc. standalone R&D / UL Testing Laboratory is located in Logan, Ohio, USA. With only a 40 foot x 40 foot (12m x 12m) foot print, and 3 stories tall (28 feet (8.5m ), this dedicated lab has over a 4 million BTUh (2050 KWh) natural gas capacity. This makes it among the world’s largest capacity testing facility that is solely dedicated to chimney and pressure stacks testing. Inside the Lab we have 2 natural gas burners used in conjunction with 3 flue gas generators as well as other testing equipment for very large diameters up to 36 and 48 inch (900 and 1200mm). An 80 channel data acquisition and computer center continuously monitors and logs testing data in real-time. The Lab is also staffed by a full time senior technician with over 25 years of specific chimney testing experience. Underwriter Laboratories (UL) witnesses our testing at this location, and we are nearing our initial goal of over 20 different UL and ULC (North American) safety Certifications. Planned next steps of UL and ULC testing will be incredible in the eyes of most American engineers as Jeremias brings more German and European technologies to the Americas. Jeremias Inc. is leading the industry in product innovations and new applications in the American markets.
