1. North American Operations Kalamazoo Plant Welcome to Kalamazoo

2. North American Operations Kalamazoo Plant In January, 2009, the Kalamazoo plant management staff met on a Saturday along with plant maintenance, electricians, controls engineers and an outside HVAC vendor to go on a “treasure hunt” to identify areas where Kalamazoo was “wasting energy” in the plant. This process works well, especially on weekends when everything should be off, to assess what’s running and to start asking questions – How can it be shut off? Should it be shut off? Why isn’t it shut off? Areas of opportunity that we looked at were lighting, compressors, HVAC (heating, ventilation, air conditioning), variable frequency drives, weld gas loss due to leakage during non production hours and equipment left on or idle. The Treasure Hunt
