LCM applications requires a high and continuous flow of nitrogen at specific purity. Swissgas provides the true first modular solution for LCMS with improved performances and reliability. Each part does a specific job: first the air compressor, of scroll technology, provides low noise operation and lower maintenance than typical piston compressors. The variable speed algorithm increase the life time of this first part. Secondly, the generator transforms the air into a 99.5% purity nitrogen. Finally, a buffer tank will smooth the operation of the whole system by reducing "stop-and-go " sequences. The modularity concept allows also to take only necessary parts when some are already in place for a personalized and flexible nitrogen supply solution.
