Industrial Gas and Air Compressors
PTC designs and supplies centrifugal, reciprocating and screw compressor packages with electric motor, steam turbine, gas turbine or expander drivers in accordance with international API standards.
Compressor portfolio
Petro Kara Energy Hiva (PTC), drawing on five decades of industrial experience and the expertise of its engineers, designs, manufactures and supplies complete compressor packages. Steam turbines, gas turbines, expanders and electric motors can be selected as drivers for air and process-gas duties. The packages are engineered to international API standards for high performance, reliability, project economy and sustainable development in oil and gas refineries, petrochemical and chemical plants, associated-gas and flare-gas gathering projects, oilfields handling sour, toxic, corrosive, explosive and flammable gases, and steel plants.
Compressor types covered
- Centrifugal compressors: API 617 and API 672 units for continuous-flow, high-pressure and continuous-duty applications.
- Reciprocating compressors: API 618 units capable of very-high-pressure operation with special gases.
- Screw compressors: API 619 units for continuous medium-flow industrial service, high efficiency and straightforward maintenance.
