Corken’s D-style oil-free reciprocating compressors utilize two sets of V-ring packing per packing rod that form a single barrier to external leakage. The lower packing set has an adjustable packing screw that is used to maintain maximum sealing performance throughout the life of the packing.The distance piece has its own line connections that can be that can be padded, purged, or vented. This allows you to choose the best method of containment for your application. For added convenience purge kits with all of the accessories needed to control the purging or padding of the distance piece are available.

Since there is no piston rod over travel between the crankcase and compression chamber, all D-Style compressors deliver oil-free gas compression. The only exception is the model D891 compressor which is not oil-free. D-Style reciprocating compressors are used when oil-free gas is required and leakage containment is desirable.

D-Style industrial compressors are compatible with a wide variety of hazardous and volatile gases such as natural gas, nitrogen, sulfur hexafluoride, propane, butadiene, helium, and industrial ammonia.

Each compresssor is available with a standard mounting or we can custom engineer a compressor package for you. We now offer an ASME B31.3 – 2012 piping option for all of our compressor packages and skids.
