The glass world will meet again at Glasstec 2010 and these last two years were not exactly the ones we expected them to be in 2008. Shortly after the show, the global economy went down and perhaps the only positive thought was that glass was not the only industry that suffered.
As a glass solutions provider, IOM/Eurotherm, experienced the same effects of the economical downturn. Having recognised the situation early, it continued to support its customers, while looking to the future by developing new ideas.
As we head for Glasstec 2010, it seems that business is starting to come back. During the last Magdeburg symposium, some of the speakers mentioned the need for the glass industry to save energy by 2oo/o in the next 10 years. This may be a harsh reality for the glass industry, as oil prices are likely to rise as soon as the economy has started to recover. The oil disaster, which took place near US shores, will no doubt adversely affect global oil pricing and energy saving politics.
Product longevity
EPower, the SCR controller line that IOM/Eurotherm introduced at Glasstec 2008, has been well-received by its glass customers, its predictive load management function benefitting many applications.
The company has improved the system by adding new power control strategies to the controller. It is now capable of controlling power in a four taps dynamic load tap changing mode, as weli in phase angle mode as in burst firing mode. At Glasstec 2010 the supplier will display the full EPower range at its stand. Visitors will be able to experirnent with ‘ioad tap changing’ and find out the benefits of this kind of power control.
Other developments
Over the last two years, the company has also installed a number of Foxboro PAC process control systems. The product is different from PLC-based process control systems as it ls a fullblown distributed control system.
One of the latest installations for a container glass furnace and forehearth system involves 22 redundant central processing units (CPUs) and all the layers in the system are fault-tolerant down to the input/output modules. This gives a high ievel of granularity in a fulty transparent programming environment. The 22 CPUs are bound together in one environment, communicating peer-to-peer to keep network load low and ensure an extremely low failure rate. Each CPU is able to ‘store and forward’ important process data at its own standalone level.
This function was developed to comply with the strict pharmaceutical regulations, 21 CRF part 11. It enables the distributed control system, in case of communication or data server problems, to store important process data at the basic input/output rack level. As soon as the data server functionality returns, the stored data is forwarded, therefore invaluable data such as CO, and NOx trading figures are not lost.
IOM/Eurotherm now introduces its latest Foxboro PAC process control hardware platform, which maximises input/output density and has increased memory and CPU capacity.
