DOUBLE STAGE SCREW COMPRESSORS D2 90-315

✓ DOUBLE STAGE AIR-END ✓ FREQUENCY CONVERTER ('' D2 V'' VERSION) ✓ EXCEPTIONAL ENERGY EFFICIENCY ✓ HIGH CAPACITIES, LOW ENERGY CONSUMPTION D2 series compressors are designed for harsh operating conditions in all types of industries, such as in power plants, steelworks, cement factories, metallurgy, chemical industry, etc. The D2 series is a reliable partner in continuous production with a 24/7 operating mode. It is designed for use in dusty environments with high efficiency. It is distinguished by long-term stable operation, as it is designed for a 20-year service life.

Many advantages in one compressor The D2 and D2 V series double-stage screw compressors combine the many advantages of built-in components that ensure high reliability of compressed air production for your plant. Compressors are available in different pressure ranges (4.5–12.5 bar), as a version with a fixed speed (D2 version), or as a version with frequency control (D2 V version). Extremely efficient double stage compression Extremely efficient PM motors with permanent magnets (IE3 class) Large oil tank and air oil separator Oil filter with independent lubrication system Integrated oil separator...

OMEGA AIR: Double stage screw compressors D2 ECONOMICAL DOUBLE STAGE DESIGN The double stage compressor design reduces the load on each stage of the compressor, leading to significant energy savings, ranging from 15 % to 30 %. Frequency speed control technology further reduces energy consumption and operating costs of your plant. D2 series models Fixed speed Frequency speed control Water cooling Extremely efficient motors Two-stage screw element Heavy-duty suction filter Converter control TEFC motors with IE3 efficiency, insulation class F, and IP55 protection are fitted as standard. The motors...

OMEGA AIR: Double stage screw compressors 5 The suction valve optimises the air supply to the screw element. The perfect aluminum design requires no maintenance, and it is distinguished by a high suction rate (700 mmHg) with a wide suction range and low energy consumption in unloaded operation. Quick check function enables unloading and closes the oil injection. A large separator tank improves the cyclone effect, which improves the process of separating oil from the air. A highly efficient oil separator ensures that the oil carryover is less than 3 ppm. The system pressure loss is less than 0,2...

6 OMEGA AIR: Double stage screw compressors D2 The robust design of the double-stage air end is a guarantee for a high-tech product and reliable The air-end has many advantages: • reduced compression ratio of each compression stage, • double stage air design for high flow rate and low energy consumption, • motor with direct drive of the air-end operating at low speed, • low energy consumption at partial load, • constant system pressure reduces system pressure fluctuations and general air needs, • low speeds of male rotors increase performance and reliability, • reduced energy consumption reduces...

OMEGA AIR: Double stage screw compressors 7 Double stage compression has many advantages over classic single stage compression; isothermal compression, lower compression ratio, higher air flow, higher energy savings, better cooling, stability and reliability of operation, longer service life, etc. Double stage compression

8 OMEGA AIR: Double stage screw compressors D2 - variable speed fan control, - compact design, - high capacity for optimised cooling, - fully enclosed housing, low noise level, - separate lubrication system, sealing and lubrication for screw elements and bearings, - separate air filter and motor cooling inlet, - separate cabinet for converter and starter, - the pressure joints of steel pipes are used to prevent leakage and premature ageing, which is often observed in flexible pipes, - reduced losses due to friction of the pipe. The low speed of the large rotor effectively reduces vibration and...

OMEGA AIR: Double stage screw compressors AIR/OIL SEPARATOR The air flow control plate in the separator changes the flow direction. Due to the cross-flow, small oil particles combine into larger ones, which are easier to separate from the air flow. The generously dimensioned separator tank (30% excess) improves the cyclone effect, which improves the process of separating oil from the air: high efficiency, oil carryover lower than 3 ppm, and high-efficiency oil filter reliably removes impurities. Due to the optimal design of the separator, the pressure loss in the system is lower than 0,2 bar....

OMEGA AIR: Double stage screw compressors D2 ENERGY SAVING TECHNOLOGY Speed control with inverter (option) The wide range of operating speeds provided by the D2 V series of compressors ensures stable, constant pressure control. With a frequency converter and savings-oriented control logic, you can optimise energy savings regardless of the load condition. The converters can react to rapid pressure changes as soon as there is a deviation of ±0,1 bar. Constant pressure control 7 main features Complete control over energy consumption Pay only for air that you consume – RS485 communication – intelligent...

OMEGA AIR: Double stage screw compressors 11 A frequency speed converter enables a soft start, reducing starting currents and thus the load on the electrical network. Extremely efficient TEFC motors (standard) Compressors are fitted with high-efficiency TEFC motors with SKF bearings, insulation class F, and protection level IP 55 as standard. High performance PM motors (optional) • PM motors exceed the requirements of IE4 standards. • efficiency is 5 % higher than with conventional motors • frequency speed control • built-in permanent magnets • high torque and low currents during start-up and...
