In March 2006 a contract was signed with Oulun Energia to supply a complete flue gas condensation plant for a boiler Topplia II. The boiler is fired with peat and has a capacity of 280MW and continuously delivers 50MW from condensation to the district heating network.

The delivery consists of two parallel condensers due to the large flue gas flow, and a complete condensate treatment with MF, UF and RO. The project was taken over by the customer in May 2007.
