Upgrading the steam and cooling systems at a machine tool manufacturing complex
- ThermalTech Engineering, Inc., Cincinnati, OH (United States)
Cincinnati Milacron, Inc., one of the world`s largest machine tool manufacturers, decided to upgrade the steam and cooling systems that serve Milacron`s multibuilding 1.5 million square foot (139,350 m{sup 2}) headquarters complex in Cincinnati, Ohio. The upgrades were begun in 1993 and were operational by March 1995. Program objectives were to: (1) Provide mechanical cooling of manufacturing areas for better temperature control to gain closer tolerances on machined parts. This was to support a corporate objective to obtain ISO 9000 Certification which has been achieved. (2) Phase-out use of ozone-depleting chlorofluorocarbon (CFC) refrigerants in existing electric chillers and packaged air-conditioning (DX) units. (3) Minimize waste oil and wood leaving the complex to reduce disposal costs and environmental liabilities. (4) Reduce operating and maintenance costs to enhance industrial competitiveness. With co-funding help from the local utility company, Cinergy Corporation, the authors assisted Milacron in analyzing the feasibility of various mechanical cooling concepts such as single vs. two-stage steam absorption vs. electric chillers. This analysis provided the data needed to select the concepts which best met the program objectives.
