Type OIB Centrifugal Compressor This Compressor features a stiff shaft design which assures an operating speed well below the first critical speed of the shaft. A wide range of stable operation is provided by these units with surge occuring at approximately 50% of design capacity. Use of adjustable inlet guide vanes can extend this to 30% of design capacity or 70% turndown.
* Poly heads to 40,000 ft. * Flows from 300000 cfm (510000 m3/hr)
Type IGC Centrifugal Compressor This compressor is suitable for use with a variety of constant speed or variable speed drivers. Local energy costs and your requirements will determine the most economical method of drive for your application. Adjustable inlet guide vanes control the capacity with a minimum loss of efficiency, and also increase the stable operating range. Adustable diffuser vanes aner available for certain applications where constant inlet temperature exists and constant discharge pressure is desired. * Polytropic heads to 50,000 ft. * Flows to 60000 cfm (101949 m3/hr)
Type H - Multi-Stage Centrifugal Compressor A choice of impeller materials provides efficient, reliable operation with a variety of process gases at varying temperatures, humidity levels and pressures. Horizontally-split casing compressors feature bearing housings that are flange mounted to the case. This design permits easy access for maintenance or bearing inspection. * Polytropic heads to 90,000 ft. * Flows from 9,000 to 125,000 cfm (15291 to 212376 m3/hr)
