Pressure maintaining system RDHS ½ – 3
The devices and components of compressed air treatment within the compressed air network are designed for load operation and the corresponding flow rates. If the pressure within the system is missing – e.g. at unload or after breaks in operation – the proper functioning of these components and thus the required compressed air quality cannot be guaranteed. In addition, when the compressors are started up, there is a risk of overloading these components due to the lack of resistance.
The electronically controlled RDHS pressure-maintaining system ensures that compressors that start up again quickly work against the specified network pressure in the area of compressed air treatment. This ensures an optimally functioning treatment system right from the start due to immediately correct flow rates. The system is designed for operation with 230 Volt alternating current.
Technical specifications
Connections: G½ – G3 inch
Max. pressure: 10 bar (on request: 16 bar)
Advantages
- Functioning treatment system thanks to correct flow rates when the compressors are restarted
- Operational reliability due to protection against impermissible flows and overloading
- Gentle pressure build-up due to electronic control
- User friendly – easy configuration and manual override in case of emergency
- Fast installation thanks to existing range with different connector widths
Electric ball valve RKE ½ – 2
The RKE electric ball valve automatically opens or closes the compressed air tank via the control unit or connects and closes areas of the network from the compressed air supply as required. This prevents e.g. an unnecessary start-up of the compressor and activities of dryers and filters during the idle times, or separates areas in which compressed air is currently not needed.
The slow opening and closing times protect the compressed air line and reduce noise in the compressed air network. The ball valve is operated with 230 Volt alternating current, but it can also be operated manually in the event of a power failure.
Technical specifications
Connections: G½ – G2 inch
Max. pressure: 30 | 40 | 65 bar
Advantages
- Cost savings through automatic blocking of compressor start-ups and other components
- Control of air flow by selectively separating or opening areas of the compressed air network
- Easy to maintain and operate thanks to a fully automatic control system
- Low-noise due to slow opening and closing times
- Safety – operation by manual override even in the event of a power failure
- Straightforward installation due to compact design and choice of different connector widths
