PROBLEM The customer had operated our water-cooled brakes on his unwind stands for eight years with very little maintenance. However, some additional demands on his cooling system resulted in some corrosion and capacity concerns. SOLUTION We closely reviewed their tension needs and thermal horsepower […]

PROBLEM Our customer operates paper converting equipment including a water cooling tension brake. Since the equipment was manufactured off-shore all of the components were metric. In this operation, the brake was the only regular maintenance item. However; given the high price and limited availability […]
