[Improvement Case] Reduced costs and effort associated with equipment maintenance cleaning.

We will introduce a case where the need for paid cleaning through outsourcing has been eliminated, achieving a total cost reduction of 1/10!

We would like to introduce a case from a company in Niigata Prefecture that is working on reducing the discharge of water-soluble waste liquids. The company had been outsourcing maintenance cleaning of its equipment, which was costly and labor-intensive, so they were exploring methods to clean in-house. After introducing a special water-based cleaning agent, the need for outsourced paid cleaning was eliminated, allowing them to achieve a total cost reduction of 1/10, even when considering the purchase costs. [Challenges Before Implementation] - Regular cleaning was necessary due to the accumulation of sludge and other contaminants on the heat transfer medium, which led to a decrease in performance. - The contaminants were so stubborn that they could not be removed even with a high-pressure cleaner at 7.5 MPa, so they were relying on outsourced paid cleaning. - When outsourcing, the challenges included the effort to package the contaminants to prevent spillage, a lead time of about one month, and costs related to shipping and cleaning expenses. *For more details, please download the PDF or feel free to contact us.*
