The mill's main-bearing lube filter elements were reaching their terminal DP change limit on an average 3-week interval, costing the company over $70,000 in additional filter expenses. In addition, the mill's ISO fluid cleanliness code was 18/15/12, which is twice the particle limit allowed in the system. Looking for a solution, the mill consulted Hy-Pro hydraulic filtration solutions experts. As a result, the paper mill was able to reach a 75% reduction in dirt and a 4x longer filter lifespan. The mill now achieves a filter lifespan of 11 weeks, with a 16/14/12 ISO code. This has saved the company $58,000 annually on the cost of filter elements and maintenance hours and helped them achieve their sustainability objectives. In this case study, we will discuss the following: •    The challenges the paper mill was facing •    How Hy-Pro helped them solve these challenges •    The results they achieved •    How you can achieve similar results for your business Click below to read the story, or use the Hy-Pro Information Portal for access.
