The mapping of the compressed air system’s functionality started with a Syyni system analysis. The Syyni analysis revealed large variations in consumption, unevenly running compressors and frequent start-ups, needlessly high output and network pressure, considerable pressure loss, and inadequate drying capacity. Dips in the compressed air network pressure rendered the settings of the main process unreliable.
Napapiirin Energia ja Vesi trusts Sarlin for compressed air
Napapiirin Energia ja Vesi Oy purchases compressed air as a service from Sarlin
Napapiirin Energia ja Vesi Oy is the regional utility in Lapland that produces heating and electrical energy, manages the water, electricity and district heating networks, and builds electrical and water networks.
The utility works with its partner network to produce its services in an environmentally friendly and cost-efficient manner. Director of Production Jukka Partanen describes the idea of the partner network:
“We make partnership agreements with professionals to support our organisation and add value to our core process.”
Sarlin chosen as the partner for compressed air
New equipment and system management by Sarlin Balance
The analysis of the compressed air system painted a clear picture for updates. Capacity was added to both compressors and dryers, and the separate working air and instrument air networks were connected.
The new equipment and the Sarlin Balance management system reduced the specific energy need of compressed air production by more than 20 per cent. The variance in pressure was reduced to 0.5 bar from 2 bar. Pressure loss has also been reduced significantly.
Previously, the intensive blasting required for ash removal would cause a sudden drop in pressure. Now the correct network pressure is maintained because the Balance system can predict the need for blasting.
Partners develop the system together
The reliability and energy efficiency of the compressed air system has been materially improved by the collaboration of the partners. The added value of the partnership is measured regularly and any problems are solved in cooperation. In addition, the partnership guarantees training and support for the use and interpretation of the Sarlin Balance management system. Sarlin monitors the functioning of the compressed air generation station remotely and prepares periodic operational reports.
