Rolls-Royce visita sito produttivo ABB in Estonia

Lo staff Rolls-Royce ha visitato e valutato un impianto ABB in Estonia in due giorni di audit nel mese di febbraio. Dopo la visita, sette generatori per diesel e motori a gas (AMG) sono stati messi in produzione.
Il 2 e 3 febbraio 2012, ABB ha accolto alcuni rappresentanti Rolls-Royce nel suo sito produttivo nel piccolo distretto di Jüri nel nord dell’Estonia.
Un accordo quadro firmato nel dicembre del 2011 impegna ABB a produrre generatori di alta e bassa tensione per applicazioni nel settore navale e dell’energia e motori a induzione per la propulsione navale e per applicazioni Rolls-Royce con propulsori azimutali. In gennaio 2012, Rolls-Royce ha ordinato i primi 7 generatori per diesel e motori a gas.
Precedentemente ABB aveva un accordo a progetto con Rolls-Royce, che prevedeva principalmente la fornitura di motori a bassa tensione. Ora l’accordo commerciale si è esteso anche alla produzione di generatori per diesel e motori a gas nel nord dell’Estonia.
“Le ragioni principali che hanno consentito ad ABB di ottenere quest’accordo quadro sono l’elevata qualità dei prodotti, l’alto livello di supporto locale professionale e il servizio eccellente” afferma l’ABB Key Account Manager Tenho Eerola. “Questo accordo è il risultato di un grande lavoro di squadra; la professionalità del reparto acquisti Rolls-Royce e il nostro team di supporto alla vendita hanno facilitato molto la conclusione dell’accordo.”
ABB ha stabilito che l’impianto di Jüri era il migliore per costruire i generatori, grazie alla sua elevata capacità.
I rappresentanti Rolls-Royce sono stati invitati a visitare l’impianto e hanno potuto ispezionare la fabbrica, esaminare il processo produttivo e valutare positivamente le capacità produttive dell’impianto ABB. Rolls Royce aveva già ispezionato gli impianti ABB di Helsinki e ha intenzione di condurre audit simili anche negli impianti ABB in Cina e possibilmente in Brasile a breve.

Desigo V5: Innovations from Siemens increase building efficiency
The Siemens Building Technologies Division has introduced version 5 of its Desigo building automation system. Its innovative products such as Total Room Automation as well as efficiency features, like RoomOptiControl and Eco Monitoring, give building operators and users an active role in energy management, leading to permanent reductions in energy and maintenance costs.
A state-of-the-art building automation system is always optimized for energy-efficient operation. However, these optimized settings may start to drift over time. One of the underlying causes is often a lack of transparency for users who simply don't know how the setpoint changes they make can impact energy consumption. This is particularly true for air-conditioned rooms which are also equipped with lighting and sun protection controls. The new version of Desigo keeps room users and building operators apprised of the building's efficiency status. Feedback to users is given using the innovative Green Leaf display, adapted to the expertise and control options of each user group. The system makes it possible to change settings if needed to restore optimal energy efficiency. A study by Technische Universität München (TUM) indicates that by actively involving operators and users in the energy management of a building, energy consumption can be reduced by up to 25% without affecting comfort.
Total Room Automation offers energy savings without reducing comfort
The open, programmable room automation range Desigo Total Room Automation (TRA) is a holistic solution encompassing the HVAC, lighting and shading disciplines. Desigo TRA uses an innovative efficience feature called RoomOptiControl. It automatically detects unnecessary energy consumption in the room and notifies users by changing the color of the Green Leaf icon on the QMX3 room control unit: If room operations are energy efficient, this icon is green. If settings made by a room user lead to unnecessary energy consumption, the icon turns red. To reset room control to energy efficient operation, the user simply presses the display and the Green Leaf icon returns to green.
Using BACnet/IP, PXC3 room automation stations—also part of the TRA package—are integrated seamlessly into the PX automation level with its primary systems (heating generators, HVAC main units and cooling generators). The primary systems are controlled directly through the demand signals from the rooms. This means that the primary systems are only turned on if needed and their operation is adjusted so it meets the room requirements without exceeding them. One room automation station can cover multiple rooms. TRA offers complete integration of KNX, DALI and EnOcean devices; existing or new sensors and actuators from Siemens can be incorporated as well.
Eco Monitoring to reduce energy consumption and wear
Eco Monitoring is another innovative efficiency feature of Desigo. It monitors ongoing operations of HVAC systems based on energy-related quality condition indicators such as readings from temperature, humidity and pressure sensors, runtime, switching behavior and operational performance of the systems. Should deviations from the target state, inefficient operations or increased energy consumption occur, the building operator is notified via the Green Leaf display on the Desigo Insight management station. Current and future international standards (such as EN 15323:2007) require such a feature in order to optimize building operations over the long term.
Desigo Eco Monitoring not only helps optimize energy consumption, it also reduces wear. Thanks to its dynamic behavior and timely reporting, the Eco Monitoring feature recognizes unfavorable system operations early on, allowing operators to intervene immediately before any negative impact occurs. If desired, operators can choose to be notified of unusual events via text messaging (SMS), fax or e-mail.
Expanded networking of the automation level
Starting with version 5, Desigo also offers expanded end-to-end networking of the automation level. Enhanced support for communications standards ensures efficient system integration. The PXC series of compact automation stations has a higher number of universal inputs/outputs, which makes them much more flexible. To protect existing investments, different device generations, such as PTM and TX I/O modules and RXC room controllers, can be used in parallel on the same PX automation station.
