Customized Gas Screw Compressor As Your Requirements
Comair gas screw compressors could be designed as per your gas requirements including flow rate, discharging pressure, working environment, explosion-proof, driver options etc; The compressing chamber or other special parts could be made of either carbon steel, copper alloy, or food grade stainless steel; the lubricating liquid could be water, diesel or methylene dichloride which will not cause any rusts, sharp shocks, or corrosions.
Compared with piston gas compressors and centrifugal gas compressors, the gas screw compressor has its own advantages.
Less parts: Piston compressors have many weary parts including piston rings, air valves, supporting rings and seal rings etc. Gas screw compressors have less maintenance parts supporting longer maintenance intervals and lower operating cost.
Smaller footprint: gas screw compressors do not cause any out-of-balance forces. So they don’t need any large foundation strengths as centrifugal compressors and piston compressors, which means a small installation area will be enough. This makes it a perfect choice for installation on a ship or offshore plateform.
Already Comair gas screw compressors have been widely used and accepted in many industries and applications, some of which are listed below:
Oil & gas: vapor recovery, flare gas capture, gas lift, LNG boil-off gas, natural gas pressurizing and transportation etc.;
Coal processing: coal gas, coke oven gas, coal bed gas;
Medical & pharmaceuticals: medical raw gas pressurizing, reaction gas pressurizing, & tail gas recovery;
Others: biogas fermentation, gas power transportation, and high pressure gas storage.
Comair gas screw compressors with its superior design do have their advantages which could bring benefits to you:
100% oil free compressed gas: if you can bear any losses on products contamination, system damages and other related extra costs, our oil free gas screw compressor could be your ideal choice. We use water instead of lubricating oil. So we can ensure the gases are totally oil free;
Environmental friendly: all the internal pipes are made of food grade stainless steel. In the compressor system, there is no lubrication oil, which could avoid any oil pollution on the environment.
Easy maintenance: maintenance fees are far less than any piston compressor and required maintenance time is just one fifth of the piston compressor. Required maintenance parts are just water filters and air filters, greatly reducing work amounts and down time.
No unbalanced forces: Comair gas screw compressors are designed totally balanced without any radial unbalanced forces.
Through all these years of development, Comair has always led the innovation progress. Several key designs make our gas screw compressor more energy efficient:
Special customized seal material: this seal material ensures 0 leakage of compressed air. Any leakage could cause severe energy wastes.
Water lubrication: most Comair gas screw compressors use water as the lubricating material. Water has the largest specific heat capacity, which means the compressing process could be more like isothermal. Isothermal compression is the most energy saving one.
Variable speed drive design: permanent magnetic motor together with VSD drive technology could automatically adjust the motor speed according to the required compressed gas amount. It saves over 30% energy compared with a fixed speed compressor.
Comair gas screw compressors could handle and compress various types of gases and gases mixtures. Some are listed below:
Natural gas, flare gas, fuel gas, butane, propane, coke oven gas, water gas, coal bed gas, biogas, industrial raw gas, oil field gas, hydrogen, synthesis gas, carbon monoxide, propylene, ethylene, methylene dichloride, ethyne, oil vapor recovery, argon, nitrogen, oxygen, carbon dioxide, hydrogen sulphide, hexyl hydride etc.
