Comparg A-Series are oil filled screw compressors designed for smooth and economical production of compressed air in industrial plants. They feature a compact, logically laid-out design and are simple to use.
Features
Up to 94% of the electric energy expended in driving a compressor may be used again in the form of recuperated heat. Comparg A-Series compressors allow heated air to be used efficiently by recovering it for production or storage facilities.
- Modern, energy-efficient air-end.
- Microprocessor controlled for optimal cost-effective compressor operation.
- Through intelligent design of all key components, internal pressure losses are kept to a minimum, resulting in noticeable savings in total energy consumption.
- Through the use of an effective oil separation system, a residual oil content in compressed air of maximum 3 mg/m3 is attained.
- All filters and separators are easy to reach for economical service.
Professional controller
The t-Log controller controls the operation of the compressor in automatic mode, and also provides the user with the necessary information about the working pressure, the temperature of the air-oil mixture, the operating time of the compressor, etc.
Reliable electric motor
A-Series compressors are fitted with quality electric motors with a high efficiency coefficient and world-class bearings from leading manufacturers. The motors are not overloaded, but have a power reserve and overheat protection for windings.
Screw air-end
The screw block features a contemporary and energy-efficient rotor design. As the pair of screws rotates, the oil under the excess pressure forms a thin oil film between the rotating bodies. This ensures contactless rotation and the associated longevity.
Separation system
Comprag compressors are fitted with an effective three-phase separation system. Most of the oil is separated under centrifugal force in the separator tank. Some of the oil is separated by gravitational force during movement of oil inside the separator. The remaining amount of oil is separated by a quality separation element. The total amount of oil in compressed air at the outlet of the compressor does not exceed 3 mg/m3.
