Efficient Multi-Model Testing with Gas Recovery.

Nolek engineered a sophisticated Helium Leak Tester with HRS for our client Danfoss, specifically for high-throughput validation of Filter Driers. This system handles six distinct product families, providing extreme sensitivity for fine leak detection while significantly reducing gas consumption costs through integrated recovery technology.

  The Challenge

Maintaining rapid production speeds across multiple component variants while managing the high operational cost of Helium tracer gas.

◈ The Solution

A multi-station automated system featuring a 4-part simultaneous output and a Nolek Helium Recovery System (HRS) to recycle up to 98% of gas.

HRS Efficiency Standards

Automated Helium validation designed for high-volume sustainability and technical precision.
