ABC COMPRESSORS has been a pioneer in the supply of high pressure compressor packages for the beverage industry. From the 80s, ABC has supplied more than 2.500 piston units in 120 countries, in close cooperation with converters, bottlers and engineering companies. In this sense, the production of PET blowing compressor units and for CO2 recovery in breweries has long been a focus for ABC COMPRESSORS.

ABC COMPRESSORS manufactures made-to-order solutions adapted to the requirements of each installation. Thanks to its horizontal arrangement, with opposed double acting cylinders and the most sophisticated engineering, ABC offers the lowest consumption ratio of the market, ensuring the reliability, energy efficiency and robustness requested by the PET blowing or CO2 recovery applications.

In consequence, the high pressure compressor is supplied complete with compressor,motor, electrical cabinet, air receiver, and refrigerated dryer, forming a compact but complete PET blowing compressor system. The set is 10%more efficient than any other compressor in the market, and with a perfectly adaptable frequency converter the saving can reach to 15%.

Additional comments

The blowing installation was located in a tropical environment with the following features: high temperatures and humidity, low-skilled technicians, problems with the supply of refrigeration water, and a technical service thousand miles away. In order to solve these inconveniences, an ABC four-stage, low speed (3,10m/s) compressor set and a closed air-water circuit cooling system, without consumption cooling system, was installed, achieving excellent temperatures below 150ºC and being ready to work between maintenance services over 8.000 hours of operation
