Energy savings of up to 6% could be demonstrated, depending on the pressure ratio or the volume flow (Picture: Aerzener)

The E-compressors come in four sizes covering a volume flow range of 900 to 6,700 m³/h and drive capacities of 55 to 630 kW. These single stage, oil-free screw compressors will be offered in two designs with differential pressures of 2.0 and 3.5 bar. Depending on the pressure ratio or the volume flow, energy savings of up to an impressive value 6% could be demonstrated. The improved energy efficiency comes from design optimization. Instead of suctioning the air to be compressed from inside the acoustic hood, cooler outside air is now fed through an intake channel directly to the intake filter. This greatly improves the specific performance of the plant. In addition, optimized inflow channels and an innovative pressure-side silencer with improved fluid dynamics and no absorption materials help to minimize pressure loss. The silencer noise level could be reduced to less than 80 dB(A), depending on the kind of operation, as a result of optimized cross sections and idealized lengths of the chambers. Moreover, by using two compensators, the system is also 100 per cent stress-free. In future, this discharge side silencer will also be designed as spark arrestor according to Atex Directive 137 for explosion-proof plants. The series is easy to service and maintain. The service life of the bearing lubricating oil 16,000 operating hours is another positive feature.
