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.
