CORKEN INDUSTRIAL COMPRESSORS

Corken’s line of oil-free industrial series (CORKEN I-Series) compressors are designed to transfer a wide range of process gases such as butadiene, hydrogen, helium, methyl chloride, sulfur dioxide, chlorine, HCFCs, exotic gases for research, corrosive biogases in landfills, and hydrocarbon gases within the oil and gas industry.

Greater CORKEN control of fugitive emissions...

For toxic, hazardous, and explosive gases, Corken’s D-style (single-distance piece with two sets of packing) and Corken’s T-style (double-distance-piece with three sets of packing) designs provide precise leakage control. When properly equipped, the Corken T-style compressors comply with the EPA’s requirements for fugitive emissions control of volatile organic compounds (VOCs).*

Multiple options to match application requirements…

Corrosion Resistant Coatings: To minimize corrosion and premature wear on critical parts, Corken offers a nickel alloy plating impregnated with fluorocarbons for all gas wetted parts.

Multiple Material Options: To increase compatibility with volatile and toxic gases, Corken offers several material options for compressor parts and O-rings.

Vertical Industrial Gas CORKEN Compressors
 
Engineered for High-Performance, Oil-Free Gas Compression
 
Water-Cooled Heads, Cylinders, and Packing
To handle a broad spectrum of process gases, CORKEN offers models equipped with water-cooled heads, cylinders, and packing assemblies. These cooling features significantly reduce operating temperatures, making the compressors ideal for high-K value gases such as argon, air, helium, hydrogen, and nitrogen—where temperature control is critical for efficiency and equipment longevity.
 
Oil-Free Gas Compression
CORKEN’s vertical industrial compressors are designed to deliver oil-free gas compression, available in both Double-Packed (D-Style) and Triple-Packed (T-Style) configurations:
• D-Style (Double Packed): Features a single distance piece containing two sets of packing rings per piston rod.
• T-Style (Triple Packed): Includes a double distance piece with three sets of packing per piston rod for enhanced leakage control and sealing performance.
 
These designs ensure complete separation between the crankcase and compression chamber. The distance between each packing set exceeds the stroke length of the compressor, eliminating rod overtravel and preventing oil carryover. Should oil bypass the lower packing set, an oil deflector ring prevents it from traveling up the piston rod. An adjustable packing screw on the lower set allows for fine-tuning of sealing pressure.
 
These features make CORKEN compressors ideal for oil-free gas boosting and vacuum service applications. Available in both single- and two-stage configurations, they are capable of achieving vacuum levels up to 23 in Hg (157 mm Hg).

Features and Benefits

Triple-Packed (T-Style) Design for Maximum Leakage Containment
 
The CORKEN T-Style (THG600 Series) compressor features a non-lubricated, oil-free design with three sets of packing per piston rod, creating two distinct barriers for external leakage control (see Figure 2). This triple-packed configuration, also known as a double distance piece design, is ideal for applications where minimizing fugitive emissions and preventing cross-contamination is critical.
 
Each distance piece is equipped with dedicated connection ports, enabling operators to pressurize, purge, or vent each chamber independently. This flexibility allows for application-specific containment strategies, enhancing safety and regulatory compliance.
 
When fitted with an optional purge kit, the T-style compressor meets EPA fugitive emission standards for controlling volatile organic compounds (VOCs). These purge kits include all necessary accessories for proper configuration and operation.
 
A key design advantage of the T-style is that the distance between each packing set exceeds the compressor’s stroke length. This ensures:
• No piston rod overtravel
• No oil migration into the compression chamber
• Precise sealing at each packing stage
 
Additionally, an oil deflector ring is installed to stop any oil that may bypass the inner packing set from reaching the outer distance piece—ensuring the gas stream remains completely oil-free.

Available in single- or double acting configurations.

  • The plain and T-style horizontal compressors
  • available in single- or double-acting configurations.
  • Single-acting configurations are ideal for applications requiring low flow and high pressure
  • double-acting configurations offer maximum capacity.
  • Single-acting configurations require a blank valve option.

External crankcase oil cooler at CORKEN compressors.

Corken’s industrial compressors are equipped with a force feed-lubrication system and external oil filter.

For high horsepower applications, an optional external oil cooler is recommended. This ensures a consistent oil temperature and an optimal service life for the compressor.

CORKEN Vertical & Horizontal Compressor Options

Purge Kit Accessories:

  • Due to new regulations and the growing number of gases posing safety and environmental hazards
  • leakage containment and control are a high priority
  • For maximum leakage control
  • Corken offers purge kits for D- and T-style industrial compressors
  • Purge kits have all of the accessories needed to purge or pressurize each distance piece
  • Each distance piece has its own line connections for pressurizing
  • purging, or venting
  • This flexibility allows the operator to choose the best method of containment for the application
  • Figure 3 illustrates how a typical purge kit operates on a T-style (triple packing with double-distance piece) vertical industrial compressor.

Piston Rod Coating Options:

  • To minimize piston rod wear and corrosion
  • Corken recommends the Nitrotec®1 coating for most applications
  • Nitrotec®1 is a special heat treated steel with a dark gray finish
  • a standard option on all industrial compressors
  • If the Nitrotec®1 coating is not suitable for the application, an optional coating is available.

CORKEN MC1002 Coating:

This coating significantly increases component life in corrosive gas service.

It will not peel or chip and offers resistance to corrosion, moisture, abrasion.

Lab tests show piston rings can last up to three times longer when used with an MC1002 coated cylinder.

  • Suction Valve CORKEN Unloaders:
  • Unloaders provide loadless starting and constant speed unloading
  • When the initial differential pressure is high, it can strain or damage the compressor and motor so loadless starting is required
  • Constant speed unloading allows the compressor to load and unload while running rather than stopping and starting in order to control the capacity

ALLOY 50 Piston Rings and Rod Packing:

ALLOY 50, a proprietary composition, is recommended when compressing a very dry gas with a high K value. These gases tend to have high operating temperatures and offer minimal lubricating qualities. ALLOY 50 extends the operating life of the piston rings and rod packing while minimizing leakage
