The Vector 6200 Series is our premium rotary screw gascompressor package and is designed specifically forapplications requiring a high level of control and where an
electronic interface is required between the control valvesand the compressor control panel.
6200 Series features include our Evolution X
microprocessor based control panel with touch-screen.
This easy to operate panel provides clear LCD read-out ofactual pressure and temperature status, shutdown set
points, operating history etc. Recycle valves are controlled
by digital smart positioners.
AVAILABLE OPTIONS:
Variable speed drives
Inlet pressure regulator or control valve
Buildings or enclosures
Customer specific control panels
Motor starter
In many applications, rotary screw gas compressors offer alower initial investment, reduced maintenance costs and
improved operating efficiencies over conventual
reciprocating gas compression equipment.
Low maintenance and high reliability are inherent withrotary screws because they have few moving parts. There
are no valves, rings nor packing to wear out or cause loss
of efficiency.
Smooth operation results from no unbalanced forces andno pressure pulsation. No foundation is required. There
are no piping vibrations from pressure pulsation.
Gas differential pressure provides oil circulation for properlubrication at differential pressures over 60 PSI. An
optional oil pump is available for applications with less than60 PSI differential pressure.
With the increasing number of low-pressure applications,
rotary screw technology has become an integral part of
wellhead compression, gas gathering and vapor recoveryoperations. It has proven to be most cost effective forconditions requiring low or vacuum inlet pressures and
discharge pressures to 200 PSIG.
Lower Initial CostsThe up-front cost of a rotary screw compressor is
considerably lower than that of a reciprocating type unit
with the same capabilities. The compressor ends arecomplete with no need for special cylinder sizing or
pulsation vessels and take up far less space in the overallpackage design. Package design also requires less
interconnecting piping, which lowers the assembly time andcosts.
Lower Operating Costs
With few moving parts and long life bearings, the rotary
screw compressor provides a lower operating cost thanreciprocating and rotary vane compressors. With properpreventive maintenance, the rotary screw compressor can
provide years of trouble-free service. They require verylittle maintenance – only changing of the oil filters regularly,
monitoring the oil for contaminants and breakdown andchanging the oil when necessary.
Increased FlexibilityRotary screw compressors are proven to be the most cost-
effective solution for low volume compression applications.
Their ability to operate throughout a wide range of
conditions gives the rotary screw a distinct advantage overall other types of compressors.
Pulsation Free CompressionRotary screw technology eliminates pulsations, common in
other compressor types, virtually eliminating any excessivevibration possibilities.
Higher Compression RatiosContinuous flow of cooling lubricant permits much higher
single-stage compression ratios.
THE LOGICAL CHOICE WHEN THERE’S NO TIME FOR DOWN-TIME
FULLY PACKAGED - Every Vector 6200 Series single-stage compressor package is completely assembled and tested underload to make sure it leaves our plant in perfect operating condition.
FIELD PROVEN DESIGN - Vector 6200 Series packages incorporate field proven LeRoi oil-injected rotary screw compressorswhich are manufactured right here in North America.
INTEGRAL GEARING – With a wide range of standard gear ratios available, LeRoi offers the most cost-effective and efficient
compressor selection in the industry. This wide selection of gear ratios, allows us to optimize the compressor performance in
relation to drive speed and horsepower.
SAE BELLHOUSING – Simplifies direct connection to the electric motor or engine, ensures perfect alignment and eliminates
the need to have a millwright perform field alignments.
LONG BEARING LIFE – Using roller bearings on the inlet end and tempered roller bearings on the discharge end results in along bearing life. All bearings also have steel cages for corrosion resistance and custom designed internal clearance.
ELECTRIC MOTORS – WEG brand Severe Duty, Premium Efficiency cast iron frame, TEFC electric motors with a 1.25 service
factor up to 100 horsepower (1.15 SF over 100 HP). Inverter duty certified for 20:1 CT and 1000:1 VT.
HEAVY DUTY CONSTRUCTION - All iron and steel construction, with no copper or copper alloys, makes LeRoi compressors
compatible with a variety of gases including both sweet and sour natural gas, biogas, syngas, nitrogen etc. Positive rotaryshaft seals keep lubricants in and air out.
FULL RANGE OF ELECTRICAL CLASSIFICATIONS – Vector 6200 Series compressor packages are available for
unclassified, Class 1, Division 2 and Class 1, Division 1 electrical classifications.
ENGINEERED FOR MAXIMUM SAFETY – All packages are manufactured to ASME code and all provincial/state electrical
code requirements. Pressure vessels are hydrostatically tested for complete user safety and equipped with approved ASME
code safety relief valves.
VARIABLE Vi/INTERNAL PORTING – LeRoi’s adjustable Variable Vi on the HGS17, HG17, HG24, LG30 and LGL30 gascompressors allows discharge porting to be selected “on the go”. This matches the internal compression to the application
requirements for maximum compression efficiency. For HG10 and HG12 units, low, medium and high ratio internal porting isavailable.
EVOLUTION X CONTROL PANEL – Evolution X is a full-featured compressor control panel that brings management of all
systems together on a 5.7” color touch-screen. Suction and discharge pressures are managed using a combination of analog
I/O and onboard PID capability. Compressor operating parameters, relay status and system fault information are clearlydisplayed on-screen, so users can easily make necessary adjustments. Because Evolution X control panels use analog
outputs and dry contacts, they can communicate with virtually any variable frequency drive or across-the-line motor starter.
OPTIONAL OPTIMIZER PLUS VARIABLE CAPACITY CONTROL SYSTEM – Applied Compression System’s OPTIMIZER
PLUS step unloading system is an available option on Vector 6400 Series compressor packages. This system utilizes a seriesof by-pass ports that are located on the side of the compressor so that progressive steps of by-pass to the inlet cavity can be
obtained, reducing the volume of gas trapped for compression. The result is a reduction in capacity and horsepower. Theamount of turndown depends on the number of ports that are opened. As each valve is fully opened the capacity will bereduced by approximately 13% and the power reduced by 6%. Depending on the compressor speed and operating conditions,
up to 50% capacity turn-down can be achieved, as well as corresponding energy saving of up to 25%.
CUSTOM DESIGNED PACKAGES – Applied Compression is dedicated to servicing custom design applications. If one of ourexisting models does not meet the exact specifications of your application, we offer custom application assistance to either
modify an existing model or develop a customer specific compressor. The flexibility of our Custom Design Services makesApplied Compression the perfect solution for your custom application needs.
