Delta Hybrid
Relying on experience in the design and production of rotary lobe blowers since 1868 and screw compressors since 1943, Aerzen has continually set new standards for quality and innovation in the field of twin-shaft positive displacement machines. This unique combined experience from the worlds of rotary lobe blowers and screw compressors is the foundation upon which the new groundbreaking and futuroriented Delta hybrid technology has been developed - the fierst series of Rotary Lobe Compressors!
Delta Hybrid, the groundbreaking Rotary Lobe Compressor, is teh result of a synergy between the rotary lobe blower and the screw compressor technologies and offers completely new possibilities for generating positive pressure or vacuum by combining the technical advantages of both concepts.A total of 7 patents or patent applications currently make the Delta Hybrid one of the most innovative products in compression technology.
Increasing Energy Efficiency and Reduce Costs
Over a ten year operating period, energy costs equate to about 90% of the total Life Cycle Costs of a compressor. With this in mind, the Delta Hybrid was developed with the focus on increasing energy efficiency and achieving a significant reduction of energy costs and greenhouse gas emissions. The ideal union of both rotary lobe blower and screw compressor technologies resulted in the Delta Hybrid, a future-oriented innovation that resuces the energy consumption by up to 15% compared to usual compressors.
A 3+3 twisted rotor profile is used for low pressure up to 800mbar (12psi) whereas a 3+4 rotor profile is ised for pressures up to 1500mbar (22psi); a compressor with optimum efficiency can be selected for the needed pressure range. Optimized fluidic design of inlet and discharge ports provides for ideal flow conditions and reduced slippage. The inlet air is sucked in on the cold side of the package and discharge silencer isolation helps maintaining a low inlet temperature, therfore increasing the compression efficiency. Moreover, the belt-driven Delta Hybrid offers significant advantage of exact sizing the greatest advantage comes from the energy that does not need to be used. In other words, a 5% excess in volume flow corresponds to a 5% higher energy use.
Further measures that improve energy efficiency:
- Very wide flow control range from 25% to 100%
- Inlet cone that reduces pressure losses (patent pending)
- Optimal air flow within the acoustic enclosure, brings cool air to the intake side and increases compression efficiency
- Silencer without absorption material and with reduced pressure losses (patent pending)
- Shaft-driven or electric motor driven ventilation fan for the acoustic enclosure
- Special sliencer insulation reduces the temperature within the acoustic enclosure and contributes to an increase of compression efficiency
- Highly efficient motors EFF1/IE2 motors (standard) or Premium Efficiency/IE3 motors (option)
- Power fluctuations even under varying inlet temperatures (summer/winter operation) are minimal compared to turbo compressors
