CORKEN INDUSTRIAL COMPRESSORS
Corken’s line of oil-free industrial series (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. See page 11 for details.
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
Water-cooled heads, cylinders, and packing...
To accommodate a wide range of process gases, Corken offers water-cooled heads, cylinders, and packing on several models. The water-cooled CORKEN features greatly reduce the operating temperature making the compressor ideal for gases with a high K value such as argon, air, helium, hydrogen, and nitrogen.
Oil-free gas compression...
Most all of Corken’s vertical industrial compressors offer oil-free gas compression in both double (D-Style) and triple packed (T-Style) designs. The D-style has a single distance piece containing two sets of packing rings per piston rod while the T-Style has a double-distance piece with three sets of packing per piston rod. Since the distance between each packing set is greater than the stroke of the compressor, there’s no rod over travel or oil carryover. In the event oil gets past the lower packing set, an oil deflector ring keeps the oil from rising up the piston rod (see figure 1 for details). Additionally, the lower packing set has an adjustable packing screw for maintaining sealing performance. All of these features enable the compressor to supply oil free gas for boosting or vacuum service. Both single- and two-stage compressors deliver up to 23 in Hg (157 mm Hg) vacuum

Features and Benefits
Triple-packed (T-Style) design for maximum leakage containment...
The CORKEN T-style (THG600 series) is a non-lubricated, oil-free design with three sets of packing per piston rod forming two barriers to external leakage (see figure 2 for details). Each distance piece has its own line connections for pressurizing, purging, or venting. This allows the operator to choose the best method of containment for the application. When properly equipped with a purge kit, Corken’s double-distance piece (T-style) provides precise leakage control and complies with the EPA’s requirements for fugitive emissions control of volatile organic compounds (VOC).* For added convenience, purge kits with all of the accessories needed to purge or pressure each chamber are available. CORKEN T-styles are typically used in of packing is greater than the stroke of the compressor, so there’s no rod over travel or oil carryover. In other words, the portion of the piston rod coming into contact with the first set of packing will never reach the second set of packing while the portion of the piston rod coming into contact with the second set of packing will never reach the third set of packing. In the event oil gets past the inner packing set, an oil deflector ring keeps it from reaching the outer distance piece.
Available in single- or double acting configurations...
The plain and T-style horizontal compressors are available in single- or double-acting configurations. Single-acting configurations are ideal for applications requiring low flow and high pressure while 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.
Vertical & Horizontal CORKEN 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 and 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
