Wellsite Compressor rotary screw packages feature;

• Lower Initial Costs
  • The 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 are complete with no need for special cylinder sizing or pulsation vessels, and take up far less space in the overall package design. Package design also requires less inteconnecting piping, which lowers the assembly time and cost.
• Lower Installation Cost
  • Packages require only two connection points, a suction tap and a discharge tap. Using quality, steel-reinforced hoses or hard piping, we can be up and running in just a matter of minutes with minimal cost. Site requirements are just as simple-we need a level, flat surface large enough for the unit to set on. Costly gravel or concrete pads are not required and all of our skid-type units can be installed using a tail-roller truck and/or trailer instead of expensive cranes.
• Lower Operating Cost
  • With few moving parts and long life bearings, the rotary screw compressor provides a lower operating cost than the reciprocating and rotary vane compressors. With proper preventive maintenance, the rotary screw compressor can provide years of trouble-free service. Our unique oil separator design provides minimal oil loss that is measured in "parts per million" instead of the "gallon per day" that reciprocating and rotary vane compressors can consume and deposit into your production equipment and sales line. The rotary screw compressor requires very little maintenance. This includes changing the oil filters regularly, monitoring the oil for contaminants and breakdown, and changing the oil when necessary. When repairs are required, they can be performed without the need for expensive specialty tools or extensive training.
• Increased Flexibility
  • Rotary screw compressors are proven to be the most cost efficient alternative for low pressure and wellhead compression applications. The ability to load the available horsepower throughout a wide range of operating conditions gives the rotary screw a distinct advantage over all other types of compressors. This flexibility makes it an excellent choice for producers and rental fleet operators.
• Increased Mobility
  • With lower installation costs, changeouts are very inexpensive and allow producers and rental fleet operators the benefit of being able to better match the compressor package to the application when operating conditions have changed. Our trailer-mounted units, with an optional gas metering system, provide an excellent mobile test package for the producer needing to evaluate an entire field or produce various wells on an intermittent basis.
• Fixed Vi Compressors
  • When sizing for an application with operating conditions that will remain relatively constant, a fixed Vi compressor is an economical solution that provides excellent service and long life. And with low, medium, and high built-in Vi settings available, we can build a unit to fit any condition you may have from vacuum inlets of 15" hg to discharge pressures of 150 psig. When properly applied , the fixed Vi compressor can be matched with a driver that efficiently loads the available horsepower within its operating range. Long-term applications in sandstone, coal, landfill, and shale gas are excellent candidates for the fixed Vi compressor.
• Variable Vi Compressors
  • When your operating conditions can vary, fixed Vi compressors can become inefficient and potentially ineffective. This can cause not only higher operating cost and inefficiencies, but equipment change outs that could cause interruptions in production. Frick compressors employ their state-of-the-art variable volume ratio technology, known as VVR. VVR technology centers around a movable slide stop that provides adjustment of the volume ratios of gas compressed. The movement of this slide stop can be controlled manually by the user or automatically through the use of pneumatics or a micro-processors. These adjustments are made with the unit running without interruption in gas production. The Frick compressors also incorporate a stepless capacity control of gas volume. This feature provides the operator the ability to adjust the output volume of the compressor from 100% down to 10% without interruption in gas flow. This feature, which provides for maximized efficiency of power consumption, can also be controlled manually or automatically.
