BOGE HST oil-free compressors
BOGE’s HST compressors produce Class 0 oil-free compressed air. The compressors are driven by a permanent magnet motor, with high energy density. The air-lubricated bearings in the drive shaft enable speeds of up to 120,000 rotations.
Cost savings of up to 30% compared to conventional oil-free screw compressors are achievable, according to the company.
The titanium impellers sit at the ends of the motor shafts, rotating at high speeds to set the intake air in motion. The kinetic energy is converted to pressure energy in conjunction with the diffuser and the spiral housing. Cooling of the air after each compression stage, and the integrated frequency inverters, allows the volume flow rate to be adjusted to the demand for compressed air.
The compressors require only half as much floor space as for oil-free screw compressors, while the weight is reduced by two-thirds. Depending on the size, the sound pressure level is between 63 and 60 dB(A). In idle mode, energy required is below 1.9% of the rated power.
HST compressors are suitable for use in sensitive production areas such as the chemical, pharmaceutical, and food and beverage industries, as well as in refineries, breweries or paint shops. An optional heat recovery system uses the heat expended by the compressor for service water heating or space heating.
The compressors are available in three power levels with a standard pressure of 7.5 bar: the HST 55 produces 7.97 m3 of compressed air per minute, the HST 110 has a performance of 17.97 m3/min and the HST 220 produces 36.57 m3/min.
