Plastic parts for Volvo and other well-known manufacturers are made in Kauhava in Finland. Enhanced customer awareness and an expansion of operations have encouraged MSK Plast to develop the highest ecological standards. The painting department is currently one the most environmentally friendly in the Nordic countries. The company’s most significant single act has been to reuse waste heat from the painting department, which saves 3800 MWh of energy per year, which would heat around 410 detached houses. CO2 emissions will drop by 833 tonnes per year.
The system collects waste heat from the painting department’s many exhaust air ducts. When the heat from the processes is recovered, the production space remains optimal and comfortable to work in. The recovered waste heat is utilized to heat process water, the painting lines’ washing water, and the building’s supply air and water. Calefa Ltd, which supplied the waste heat reuse system, improves its industrial customers’ productivity as well as the reuse of energy. MSK Plast previously experienced wastage and a slowdown in turnaround times during the most humid seasons when the air humidity in the painting process would rise too high. Calefa’s heat pump technology solution is also utilized to dehumidify the air in the painting department.
“This is of great importance for product turnaround times. When the product is ready in one go, more parts get completed“, says MSK Plast quality engineer Suvi Paavola. Dehumidification of the paint shop is an added value that comes with the waste heat reuse system. By reducing wastage, it brings additional savings to the environment and the factory’s costs.
EHPA invites everyone to submerge themselves in the possibilities that heat pumps are capable to offer in several industrial sectors. To read more stories the updated booklet is currently available on EHPA’s website.
