Modine Manufacturing (NYSE: MOD) is a US thermal management company established in 1916. With the global headquarters 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.
The Process
At their Mississippi facility, Modine manufactures compressor coils for their HVAC systems. Once they complete a compressor coil, they test it for 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 of bubbles indicates a leak.
The Problem
The test water quickly clouds 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-free 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 by adding color and enhancing the formation of oil-metal-dirt curd on the surface of the water. It also contributes to an accumulation of debris on the bottom of the pools which requires regular cleaning.
Modine 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 time consuming.
The Solution
Glanris, in partnership with a regional water services company, designed the GESO 2P mobile skid filtration system that skimmed the contaminants off the water surface, and then passed them through exchange tanks containing Glanris 901x 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 of visible debris. Over the course of daily operation, the accumulation of debris on the bottom of the tank was also eliminated. The portable design of the skid allows it to be used on multiple pools within the plant.
