T-Style Oil-Free Reciprocating Compressors

T-Style Oil-Free Reciprocating Compressor Overview 
The T-style is an oil-free compressor has three sets of V-ring packing per packing rod that form two barriers to external leakage. The barriers are also known as distance pieces. The lower packing set has an adjustable packing screw that is used to maintain maximum sealing performance throughout the life of the packing. Each distance piece has its own line connections that can be padded, purged, or vented separately. 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 each distance piece are available.

Since there is no piston rod over travel between the crankcase and compression chamber, all of Corken's T-style reciprocating gas compressors offer oil-free gas compression. T-Style compressors are used when oil-free gas and maximum leakage containment are critical. T-Style industrial compressors are compatible with a wide variety of hazardous, volatile, toxic, and corrosive gases such as chlorine, vinyl chloride, methyl chloride, sulfur dioxide, butadiene, hydrogen, helium, and many more.

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.

  • All cylinders and heads are made of ductile iron for maximum thermal shock endurance 
  • The T-Style configuration offers the highest level of of containment for your application 
  • Since the T-Style packing configurations eliminate rod over travel, you get deliver oil-free gas compression 
  • The two distance pieces can be purged or pressurized for maximum leakage control 
  • Valve design offers quiet operation, high efficiency and greater durability 
  • The step-cut design of the self-lubricating piston rings provides higher efficiencies during the entire life of the piston ring 
  • Positively locked pistons allows end clearance to be precisely set to provide maximum efficiency and long life 
  • Piston rod seals minimize oil carry over and maximize leakage control. 
  • Packing sets are a spring loaded seal design that self adjusts to compensate for normal wear 
  • Adjustable packing screw ensures maximum sealing capacity throughout the life of the packing 
  • Cast iron crossheads provide superior resistance to corrosion and galling 
  • Pressure-lubricated crankcase with filter keeps the internals well lubricated at all times and minimizes premature wear
