News: AAA Says Record Number of Americans Will Hit the Road Over July 4 Holiday
GFS announced it has made another move to reduce the environmental impact of its manufacturing facilities. By installing heat recovery units on each of its three spraybooth exhaust stacks at its Osseo, Wis., facility, GFS can use the heat generated during the operation of these spray booths to control the temperature within the manufacturing shop itself.
When the spraybooths are being used, typically to paint structural steel and other components, the hot exhaust air is passed through three heat exchangers (one on each exhaust stack), which use this heat to provide warm air for the production shop area. By reusing the heat generated by the spraybooths, GFS says it was able to significantly reduce the use of its facility’s existing heating system. The 60,000 CFM air makeup unit currently installed will be replaced with a 10,000 CFM unit, while still providing the same work environment for employees.
In the analysis done by the Focus on Energy program, it’s estimated that these changes will reduce GFS’ electrical consumption by over 31,000 kwh per year and its natural gas consumption by over 23,000 therms annually in its Osseo, Wis., manufacturing operation.
