WEKA has been manufacturing marine products since 1957. The core business is boxcoolers which are used for inland waterways and sea-going vessels. Weka offers a range of materials for different applications. This is for economical as well as for environmental reasons. Boxcoolers are used for cooling of diesel engines between 3 and 30,000 kW. Boxcoolers have several advantages compared to conventional cooling methods: lower weight and price, easier maintenance, higher reliability - especially in dirty or contaminated water. WEKA has taken the boxcooler principle to new hights of performance. Recent application and technology development has resulted in a product which competes successfully with conventional cooling for diesel engines in almost any application.
