Sundyne's PPI® Line of Diaphragm Compressors for Environmentally Safe & Leak-Free Processing of Critical Gases
Sundyne’s PPI diaphragm compressors deliver non-contaminating gas compression, through a leak-tight mechanism with static seals that do not need to be purged or vented. A set of metallic diaphragms isolates the process media from the piston & piston rings to completely eliminate the risk of cross contamination. Sundyne’s PPI compressors present zero leakage threat to the atmosphere, providing an ideal solution for safely handling ultra-pure, corrosive and volatile gases.
All models can be built to meet API 618 standards where applicable to diaphragm compressors. These machines are available in a variety of flexible configurations and sizes, making them easily customizable to fit a wide range of applications in the Hydrogen processing, petrochemical, refining, electronic gas, specialty gas and poly-silicon production industries.
