About ALPS Inspection

ALPS  manufactures systems for non-destructive leak testing of empty containers and packages

In-line Leak Detection Systems for Every Industry

Industry leading inspection systems to monitor and improve plastic container production. 

Air Logic Power Systems, ALPS Inspection, was founded in 1974 and manufactured its first leak tester in 1978.

The first high speed rotary system for non-destructive leak testing was supplied in 1985 for the rapidly expanding high density polyethylene, HDPE, plastic container market. In the 1990s, ALPS developed its first electronic leak test circuit and began to focus on non-destructive leak testing for the packaging industry.

Growth into the empty plastic container leak testing markets continued in the 2000s, especially for high-speed polyethylene terephthalate, PET, container applications. The ALPS NexGen Rotary container leak tester was developed for speeds up to the 1,200 bottles per minute, BPM, (72,000 bottles per hour, BPH) range.

In 2000, ALPS joined the TASI Group of companies. This partnership has allowed ALPS to join a select group of other leak detection companies and widen our expertise in the packaging integrity industry. This growing partnership has allowed ALPS to diversify into non-destructive leak testing of filled and sealed packages and additional empty container markets including metal and plastic cans and closures.

For lower speed non-destructive leak testing applications, ALPS developed lines of high speed linear leak testers with fixed and moving test heads. ALPS currently supplies the top 10 bottle blow molders in North America.


"For almost 50 years, ALPS Inspection has been collaborating with customers to provide leak testing solutions. Our expertise and customer support has made ALPS a valuable partner in protecting our customers' inventory."
