Pulp and paper technologies supplier Valmet has been contracted to upgrade the coating section of the board machine 5 at Stora Enso Imatra Mills, Tainionkoski in Finland.
As part of the project, Valmet will add electric heated OptiDry Coat air dryers and increase the drying capacity in the coating section.
The company will also add a new wire loop to the existing dryer group and automation.
According to Valmet, the upgradation will increase energy savings, while reducing emissions.
Valmet EMEA senior mill sales manager Kimmo Vehmas said: “The delivery helps the customer to take another step forward on their path to a CO2 free future.
“By replacing the old gas heated dryers by modern electric heated air dryers, the customer can reduce energy consumption for the existing board grades and ensure higher production capacity.
“The new wire loop will create an additional draw point for the web and allows controlled operating in the modified area. This will bring more safety in tail threading and minimize oil leakages.”
Financial value of the order has not been disclosed, but deliveries of this size are typically worth approximately €5–8m.
Valmet will start installations in the fourth quarter 2023.
Founded in 1935, Stora Enso Imatra Mills comprises two production units, namely Kaukopää and Tainionkoski.
The mill is one of the largest producers of consumer packaging board in the world, with annual production capacity of 1,200,000t of consumer packaging board, 1,300,000t of pulp and 455,000t of polymer coating.
In September this year, Cheng Loong Binh Duong Paper Company, a subsidiary of packaging company Cheng Loong, ordered key technologies from Valmet for its new board machine in Vietnam.
