Modine - Case Study
Modine Manufacturing (NYSE: MOD) is a US theimal management company established in 1916. With the global headquar-tets in Racine. Wisconsin, and manufacturing facilities around the US. Modine is a core manufacturer and producer of many integrated heating and cooling solutions for the HVAC industry.
At their Mississippi facility. Modinc manufactures compfossor coils lot their HVAC systems. Once they complete a compressor coil, they test it tor leaks. The method used is to seal one end of the compressor and pressurize the other end. Upon lowering the coil into a large tank of water the presence ol bubbles indicates a leak.
The test water quKkly ctouds and is fouled with the oils, solvents, and lubricants used In the coil manufacturing High-clarity water is mandatory to the QA process to guarantee leak-tree COilS. In addition to dirt, oils and solvents, the leaching of copper and other metals into the water contributes second-hand clarity problems to the process t>y adding color and enhancing the formation of oil-mctal-dirt curd on the surface of the water. It also contributes to an accumulation of debn`s on the bottom of the pools which requires regular cleaning
Modinc explored treating these challenges with other technologies without success and previously resorted to manual tank cleaning. This involved draining the tank, scrubbing the tank with caustic chemicals and then refilling the tank. This was expensive and lime consuming.
Glantls. In partnership wlih a regional water services company, designed a the GESO 29 mobile skid filtration system that skimmed the contaminants olf Hie water surface, and then passed them through exchange tanks containing Glanrls 901/ media The media did not foul in the presence of the dirt, oils and solvents contaminants. Within a few minutes, the clarity of the water began to Improve and within two hours, the water surface was clear and virtually fee ol visible debris. Over the course ol dairy operation, the accumulation of debris on ihe bottom ol the lank was also eliminated. The portable design of the skkf allows It to be used on multiple pools within the plant.
In addition to the process improvements the implementation ol Glanris technology eliminated the need of 20 man-hours per month to clean and refill the test ponds. It also eliminated the discarding of 5.000 gallons of water to drain. These were the savings for 1 pond. The customer uses this unit on multiple ponds.
According to Michael Franklin. Facility Manager. Modino Manufacturing Company. "The Glanris Filtration Skid has provided clear water, facilitated a more efficient QA process, minimized maintenance costs and allows us to reuse, instead of dumping our wastewater*
