LRP-20: leak detection testing machine 

With the Sprimag leak detection testing machine LRP-20, aluminum tubes can be tested reliably for leaks and cracks. The concept of the machine is based on a modular system and can be used flexibly as LRP-20 in front or as a combimachine TGA-200L after the capping machine.
