Electric Motor Booster Series

Posted by Nick Rebers, Mechanical Engineer

Gas Compression Systems, Inc. extends its offerings with the Electric Motor Booster (EMB) Series. This electrically-driven booster eliminates the need for filtered, dried air by instead driving GCS’s proven reciprocating piston technology with a cam mechanism (see animation below). The EMB utilizes a variable frequency drive to control cycle rate with ease, delivering over 4 cubic feet per minute at top speed. With over 2,000 hours of testing, the Electric Motor Booster is ready for pipeline applications. It only requires one-third the horsepower of a regenerative turbine booster at only one-fifth the cost. The brochure is available for download on our Products page.

Midwest Pressure Systems, Inc. Spin Off

Posted by Matt Johnson – General Manager.

On January 1st, 2017, the gas compression business unit within Midwest Pressure Systems Inc. will become Gas Compression Systems, Inc. and Midwest Pressure Systems, Inc. will begin operations from Indiana.  The focus of each corporation is described below.

Gas Compression Systems, Inc. (GCS) will continue serving the Oil & Gas industry by manufacturing and supporting Dry Gas Seal Boosters (DGSB) and other compression products from our factory in Bensenville, Illinois.  The GCS products, and guiding principles (focused on quality, safety and customer satisfaction) remain the same.   The rebranding and additional manufacturing capacity align well with the GCS growth strategy.  We look forward to serving you as GCS and thank-you for your business.  Contact us if you have any questions.

Midwest Pressure Systems, Inc. (MPS) continues to focus on manufacturing air and inert gas pressure boosters and has relocated to a new facility in Valparaiso, Indiana.  The relocation to Indiana expands the capacity to deliver standard, custom and innovative solutions.  The MPS products, guiding principles, capabilities, ownership and brand remain the same.  We look forward to serving you from our new location.   Visit our website: https://www.midwestpressuresystems.com


New Dry Gas Seal Booster (440ANV085-0000)

Posted by Chris Ashworth, Mechanical Engineer

Midwest Pressure Systems expands its DGSB product line with a new Dry Gas Seal Booster model (440ANV085-0000). This booster was built to be cost effective for specific applications. The final booster design successfully managed more than 20,000,000 cycles during testing without issue and with normal wear. This booster has a 316L SS process gas section and an anodized aluminum drive section. It provides high flow up to 10.2 Am3/hr and differs from our previous designs because the control valve mechanism is machined into the air cap. The booster can be assembled with any o-ring type to match environmental requirements.lcb

Gas Booster – Functional Animation

Post Updated by Aaron Sebby, Assembly Manager

As a service to our engineering audience and customers, a brief animation has been created to show how our Dry Gas Seal Boosters function. Pay close attention to how the control valve, pilot valves and check valves work in concert with air pressure input to amplify the pressure of air, nitrogen, natural gas, oxygen and any inert gases. Please call if you need further information on how our products can be used for your application.

Gas Compression Systems(formerly Midwest Pressure Systems) Manufactures Boosters for FPSO Vessels

Posted by Bob Vogt, Chief Engineer

Gas Compression Systems(formerly Midwest Pressure Systems) was awarded a contract to manufacture 72 Dry Gas Seal Pressure Boosters designed to protect turbo-compressor mechanical seals during start-up and settle-out operating conditions. The boosters will be installed on eight FPSO (Floating Production Storage Offloading ) vessels off the coast of Brazil to facilitate production of offshore petroleum reserves. Delivery started in summer of 2013 and will extend through spring of 2015.

The boosters (with pressure ratings of 2900 to 8000 psi) are manufactured using corrosion resistant 22% chrome duplex and 316L stainless steel. They are equipped with integral filters, explosive decompression resistant o-rings and a piston rod design which reduces pressure pulsations during operation.

Positive Material Identification (PMI) and Traceability for Dry Gas Seal Boosters

Posted by Bob Vogt, Chief Engineer

Midwest Pressure Systems manufactures hundreds of dry gas seal pressure boosters annually. Specifications of the raw materials used for machined, process-gas-wetted components (we use DFARS compliant stainless steel) are available for every booster. Most stainless steel component are chemically etched to enable traceability of the raw material to the steel mill, heat number and test measurements recorded in the Material Test Report (MTR). The MTR format meets European Community Standard EN10204 3.1 and we provide this documentation at no additional charge.

For customers who require additional assurance that individual components match the mill documentation we offer Positive Material Identification (PMI) as an option. PMI is performed using a Thermo Niton XL3T XRF scanner. Each component carries an additional chemically etched number traceable to the individual PMI report. Correlation of the PMI results and MTR data provide additional confirmation that the material documentation is correct.


552 Dry Gas Seal Booster Product Line

Posted by Chris Ashworth, Mechanical Engineer

As the oil and gas industry’s range of environments expands the need for higher pressure dry gas seal boosters becomes more predominant. Over the past year Gas Compression Systems (formerly Midwest Pressure Systems, Inc.), Inc. has received multiple inquiries with process gas pressures of 414 bar (6000 psi) and 483 bar (7000 psi). In response to this demand Gas Compression Systems has expanded its dry gas seal booster product line to include a 552 bar (8000 psi) rated booster. More information about the 552 bar booster can be found on our Products page.
