Fast and efficient helium recovery
Helium is considered to be the most efficient tracer gas for leak detection in refrigerators, freezers and air conditioners. To ensure the highest possible production efficiency, manufacturers expect low helium consumption, fast recovery speeds and minimum maintenance in their recovery equipment. Designed specially for use with helium, the new HRM6 (Helium Recovery Module, 6 bar) provides an easy and efficient way to increase production and quality. Featuring a new and unique oil-free compressor, the HRM6 is designed for recovery pressures up to six bar. Combined with the PROTRACE leak detection system, the HRM6 is a competitive solution that can meet the highest demands with regard to flexibility, safety and ease of use.
The heart of the HRM6 is the brand new AGRAMKOW-designed oil-free compressor. Specially developed for use in helium based test systems, the oil-free compressor ensures that the leak detection equipment does not introduce oil particles to the application. This ensures both high production up-time and the best possible working conditions for the sniffer, resulting products of consistent high quality.
Constant mix control and on the-fly helium concentration regulation
The ability to ensure a stable helium mix is a critical element towards achieving high leak detection quality and overall production efficiency and up-time. In order to make sure that the mix is precise, the HRM6 constantly monitors and controls the helium concentration, thereby keeping levels within the predefined parameters. This is a clear and time-saving advantage over systems that rely on completely emptying and refilling the buffer tanks, when the mix needs to be refreshed.
A typical test is conducted with a 50% helium mix and looks for total leaks up to 5-10 g per year. If the mix is wrong by 10%, leaks may in fact be higher than measured. In a system with six joins a 10% error in the mix will result in an increased leak rate of 3 g per year, 60% higher than what was measured.
