From the 1920s

Reducing and capturing dust emissions transformed industrial production, making it more economically efficient, environmentally friendly, and humane. Before long, the term »BETH® Filter« became synonymous for dedusting itself.

1956

BETH® expanded its product range to include both wet and dry electrostatic precipitators.

1993

Miniaturization research project of ESPs completed

BETH® Mini-ESPs were introduced, expertly designed to meet the needs of smaller boilers with a thermal output of up to 1 MW. These compact units are perfect for installation in tight spaces, such as basements, making them an ideal solution for small-scale operations without compromising on performance.

2007

In 2007, BETH® transitioned to 3D design, revolutionizing our approach to construction. Today, we also leverage 3D technology in project planning, allowing customers to visualize their future plant with stunning realism, even in the early stages of proposals and planning.

2013

BETH® has joined forces with R&R-Technik, forming the newly unified entity, R&R-BETH®.
