About Us


Focus on Safety, for a clean environment

  Since five decades, nearly 1 millon ASF leak detectors have been installed in consumer heating oil facilities, gas stations, tank farms and industrial plants. This confirms the reliability of our products for monitoring of water-polluting liquids in double-walled tanks and piping.

All our leak detection systems working on the pressure or vacuum principle are corresponding with DIN EN13160 Class 1, and are approved by the DIBt (German Institute for Building Technology).

Since the merger with Gardner Denver, Inc. in 2005 and formation of the Thomas Products Division, we are part of one of the world's largest manufacturer and supplier of pump solutions for various applications. The environmental protection is one of the main activities of the company. With high standards and application specific product solutions, we contribute to the active protection of our environment.
