The P20H033A represents a milestone in scroll technology innovation, achieving the highest discharge pressure ever recorded on a scroll compressor. Using a volume ratio of 1.3, the compressor is engineered to boost natural gas from 110 bara to 113 bara. The heavy-duty design operates 100% oil-free and displaces 100 cm3/ Rev. at a max. running speed of 1,800 RPM.
To avoid contamination of the high-pressure natural gas, the design uses the same oil-free scroll technology Air Squared is known for, along with a magnetic coupling configuration. This magnetic coupling configuration allows the unit to be classified as “semi-hermetic” and isolates the motor from the pressure envelope. While engineered for use with natural gas, the patented semi-hermetic sealing features make the unit compatible a number of working fluids, opening the door for use in several new industrial gas applications.
P20H033A development required several design iterations, extensive safety validation, and spanned a period of over four years. Pilot product is planned for 2017, with sample units available by the end of the second quarter.
