There is a continuous need for paper manufacturers to reduce their environmental impact. Valmet is contributing to this need by introducing SealFlo, an easy upgrade for suction roll lubrication showers.

"Valmet's new SealFlo technology reduces water consumption by as much as 50%, while maintaining or improving lubrication results," says Pekka Kivioja, director of Roll Maintenance at Valmet.

Worn, aged and outdated showers and nozzles lead to substandard lubrication results and consume excessive amounts of water. The new SealFlo axial seal lubrication shower from Valmet features a design which improves the lubrication process, as well as reducing the roll's environmental impact through significantly reduced water consumption.

Significant savings
 
In addition to improved lubrication results, many applications show an improved moisture profile and reduced costs of shower water preparation. Kivioja gives an example: "On a paper or board machine, this could mean savings of as much as 2,500 to 5,000 euros per roll meter per year, resulting in average savings of 100,000 to 200,000 euros a year on a ten-meter wide machine that has four suction rolls." The improved shower functionality also has a positive effect on the lifespan of the axial seal and on the suction roll shell.

This modification is now available with suction roll maintenance through Valmet's extensive roll service network.

Valmet Corporation has placed an order with Luvata for 900-industrial heat exchangers valued at EUR 5.7 million. The industrial coils will be used in paper pulp dryers at Valmet customer facilities in Brazil and Indonesia.

With each heat exchanger weighing approximately 2-tons and measuring approximately 6 x 1,5 x 0,5 meters, the total project will involve over 217-tonnes of steel tube, 900-tonnes of steel bands and more than 143,800 tube plate drill holes, all delivered in two fixed delivery months.

"We have a very strong supplier network, and Luvata is one of them,” says Hannu T. Pietilä, Valmet Area President, Asia Pacific.  “The evaporation system and pulp dryers delivering to Indonesia will be the largest in the world.  This requires an unprecedented scale of pieces and parts that must all come together in a well-organized fashion.” 

“We’ve designed and manufactured high-quality coils and coolers for industrial applications for over 70 years.  Today that’s no longer enough,” indicates Mattias Lindhe, Commercial Director EMEA – Industrial with Luvata Söderköping.   “We must also deliver complex, logistically challenging, turnkey supply solutions.  And that’s when Luvata excels.”

Valmet signed a contract with OKI Pulp & Paper Mills to supply key technology for a pulp mill project in South Sumatra, Indonesia. The new mill is expected to produce approximately 2 million ADT (air dry tonne) of pulp annually. The commercial production is expected to begin in 2016.

Valmet will also supply two pulp drying lines to Klabin's new plant in Ortigueira in Parana, Brazil. The annual production capacity of Klabin's new plant will be 1.5 million tons, with start-up of the new plant scheduled for the first half of 2016..
