Ro-Flo’s low and high pressure models are flow-matched to enable two stages of compression utilizing a single drive. The compressors are coupled together and then coupled to a drive, with both stages operating at the same speed.
2-Stage Systems Allow Far Greater Range
Variations on this standard setup include independent drives and Ro-Flo® models specifically selected to handle dissimilar flow requirements at different speeds. An intercooler and knockout vessel are typically required inter-stage to remove the heat of compression and any free liquids from the gas stream.
When Ro-Flo compressors are configured as two-stage systems for compression applications, they can produce gas discharge pressures up to 200 psig (13.6 barg). In vacuum operation, Ro-Flo’s achieve vacuum levels as low as 0.7 psia (5 kPa absolute).
Improved Reliability and Efficiency
While two-stage compression systems require a greater initial investment, they are often the most cost-effective solutions for sour, acidic, or heavy hydrocarbon gas streams that can negatively impact the reliability of alternative compression technologies. In vacuum service, their superior efficiency further reduces the operating costs, providing a compelling return on investment.
