VRS-4
Arrow Engine and Compression is proud to launch the next generation in a long line of proven and reliable compressors – the VRS-4 gas compressor. The new VRS-4 is a four-throw separable reciprocating gas compressor built on the foundation of its predecessor, the VRS-2. The horizontally opposed cylinders are accurately balanced for smooth running and long lasting durability at 1800 RPM. Unlike many other reciprocating compressors, the VRS4 has a unique four-throw crankshaft configuration that eliminates opposing cylinder off-set and the vibration associated with traditional designs.
The absolute alignment of opposing cylinders provides perfectly balanced weight distribution and symmetry. The elimination of vibration associated with horizontal couple, inherent with traditional designs, along with state-of -the-art engineering design and rugged construction, make the VRS4 a truly balanced, high-performance, durable compressor specifically designed for continuous operation at high speed. The 1800 RPM speed design, 550 horsepower rating and 20,000 pound combined rod-load capability make the VRS4 a perfect fit for direct coupling with today’s higher speed gas engines.
The Arrow VRS-4 can be packaged for single-stage up to five-stage applications with cylinder size from 1.375” to 10”. Cylinders are air-cooled which reduces packaging and maintenance costs. As a standard feature, cylinders have a variable volume clearance pocket for flexibility and adjustment to allow accurate fits for changing field conditions.
The use of a pressurized lubrication system, highly efficient Hoerbiger valves, industry proven accessories, innovative engineering design, and close attention to quality make the Arrow VRS-4 gas compressor unequaled in the industry.
