T-Style Oil-Free Reciprocating Compressors

T-Style Oil-Free Reciprocating Compressor Overview 
Corken's T-style horizontal reciprocating gas compressors have three sets of segmented packing per piston rod that form two distance pieces. Depending on your application requirements, the distance pieces can be pressurized, purged or vented. T-Styles are available with two packing configurations that deliver maximum leakage containment and oil-free gas compression. Unlike Corken's vertical reciprocating compressors that use a V-ring packing design, the horizontal compressors use a segmented packing design to seal the piston rod.

The T-Style horizontal compressors are oil free so there's no contamination of the process gas stream. Since the distance between the packing is greater than the stroke of the compressor, there's no rod over travel or oil carryover. In other words, the portion of the piston rod that comes into contact with the first set of inner packing packing will never reach the seond set of middle packing. Likewise, the portion of the piston rod that comes into contact with the second set of middle packing will never reach the third set of outer packing. In the event that oil gets past the inner packing set, the oil wiper rings keep the oil from reaching the outer distance piece. This feature allows the compressor to supply oil-free gas whether it's being used as a simple gas booster or for vacuum service. T-style compressors are typically used in toxic and corrosive applications where oil-free gas and maximum leakage containment are critical.
 

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.
