New screw compressors for the entire Delta Screw series

The screw compressor packages of Delta Screw series are completely tailored to practical demands. They are ideal for the dry and clean compression of air, neutral gases and special gases and are used world-wide in many industrial applications, such as in the pneumatic conveyance or in chemical processes. Innovations made by AERZEN continue to keep driving the development of the compressor technology. The topic energy efficiency has top priority for AERZEN when designing a new series. Thanks to many adjustments of the acoustic hood design and the use of components specially adapted to the system, an energy saving of up to 6 % could be obtained with the new compressor series.

The flow-optimised cooling concept supplies an additional advantage relating to energy efficiency. By the supply of process air via intake ducts from the outside, the efficiency of the compressor package had been significantly improved.

An important component of the Delta Screw series is the comprehensive accessories programme. Especially in case of high-tech applications relating to high system pressures or reactive production ranges, the highest possible safety must be guaranteed. In order to detect damages of the compressor stage at an early stage, AERZEN GmbH provides its customers with comprehensive solutions for the vibration measurement and analysis.

By means of SPN nipples, and using an existing measuring system, the customer can identify independently any deviations from the standard. Alternatively, vibration sensors can be connected to an existing AERtronic control system and the measured values can be displayed. A permanent monitoring of the packaged unit can be realised completely and automatically by a connected vibration analysis system. This enables the customer to perform besides a vibration measurement an independent analysis on rotor bearing level. As final stage of expansion “Delta Real Time Monitoring” monitors vibrations, the pressure and the temperature of the machine via sensors. All of the measured values of up to eight diagnostic units are merged here in real time in an independent switch cabinet and these are transmitted immediately via internet, ethernet or GSM modem to a special server AERZEN, where they are monitored at any time. Trend deviations are identified and countermeasures are introduced.

Optionally, VM and VML compressors have pressure retaining valves and overflow control valves to reduce excessive volume or to avoid pressure variations, which could damage the entire packaged unit sustainably. To cool down the process air, air-air aftercoolers including cyclone separators and automatic condensate drains are available as well. The accessories are completely tailored to match the customer process and the compressor package. The flexible concept of series Delta Screw additionally permits customised special solutions, as for example special motors or acoustic hoods for special ambient conditions.

This new series of E compressors includes 6 sizes in the volume flow range from 330 to 7,000 m³/h and drive capacities from 30 to 400 kilowatts. VM 30 and VML 35 cover a volume flow of 330 to 2,590 m3/h and a maximum differential pressure of 2 or 3.5 bar.
