Compressors and boosters

Compressors and boosters are designed to increase pressure and move gas mediums. Such equipment is used in various industries, including fuel and energy, oil and gas, metallurgical, chemical, food and others.

Our company implements projects based on reciprocating, screw, centrifugal, liquid ring and diaphragm compressors, as well as other auxiliary devices like boosters, gas blowers, air fans, smoke exhausters, and Roots-type blowers.

GazSurf offers time-proven technologies from leading Chinese companies that supply compressor equipment all over the world. We work directly with reputable manufacturing plants and have a team of technical specialists whose expertise allows us to execute projects of any complexity.

Types of supplied compressors

Screw Compressors

• with oil injection into the compression chamber
• oil-free (dry) compression
• with a separate lubrication system

Compressed medium: hydrocarbon gases, various refrigerants, hydrogen and HBG, air, gases with high hydrogen sulfide content and other aggressive components.

Screw compressors are widely used in various technological processes. They are utilized in cooling units, as well as for supplying fuel gas to gas turbine units and compressing natural gas on fields. Due to their compact size, screw units are often supplied in a block-modular design for areas with adverse climate conditions. Upon request, equipment can be designed according to the international API 619 standard.

Reciprocating Compressors

• lubricated
• non-lubricated (dry) compression

The driving mechanism can be either an electric motor or a gas engine.

Compressed medium: process gases in the chemical and petrochemical industries, such as hydrogen and HBG, natural and associated gas, air, and its separation products (nitrogen, oxygen).

Reciprocating compressors find extensive use in oil refineries, as they are involved in all key oil processing processes: hydrodesulfurization, cracking, catalytic reforming, catalytic cracking, flare gas recovery and others. Upon request, equipment can be designed according to the international API 618 standard.

Centrifugal Compressors

• multi-stage design
• single-shaft design (barrel type)

The driving mechanisms can be electric motors, steam turbines, or gas turbines.

Centrifugal compressors are used to move large volumes of gas with no oil involved in the compression process.

Compressed medium: hydrocarbon gases, refrigerants, hydrogen and HBG, air and its separation products.

Centrifugal compressors find wide applications in gas, chemical, petrochemical, glass, power generation, and metallurgical industries. They offer high reliability, and the first technical maintenance of the centrifugal unit occurs only after 3 years of continuous operation, ensuring low maintenance costs and operating expenses. Upon request, equipment can be designed according to the international API 617 standard.

Diaphragm Compressors

Diaphragm compressors are used in various technological processes that require gas compression to high pressures with a high purity of the working medium.

A diaphragm compressor is a modification of a classical reciprocating compressor where gas compression occurs with the help of a flexible diaphragm. This design provides a tight compression without leaks or contamination of the working medium, making diaphragm compressors ideal for handling toxic and explosive gases.

Compressed medium: inert, toxic, flammable, explosive or radioactive gases.

Liquid Ring Compressors

Liquid ring compressors find wide applications in the oil and chemical industries, where the working medium includes explosive, toxic, and aggressive gases and vapors causing corrosion, as well as wet mediums where condensation occurs inevitably during compression.

Types of supplied boosters

Boosters, gas and air blowers, axial, centrifugal and rotary fans are used for process gases, degassing gases and exhaust gases transfer in metallurgical, mining, chemical, and oil and gas industries.

Roots-type boosters find extensive use in the food and chemical industries, as well as in wastewater treatment plants.
