IPEX Inc.
The Story
For IPEX, energy conservation is part of its corporate Environmental Management Program.
The Background
 |
Derek Sephton, Maintenance Manager |
IPEX Inc. designs and manufacturers one of the world's largest and most diverse lines of integrated thermoplastic piping systems. By looking "outside the box" for energy efficiency opportunities at its Langley plant, IPEX found a key opportunity for improvement in the water cooling system.
IPEX needs process water at 60°F temperature for its manufacturing process, but was incurring high energy costs to cool plant process water.
Initiatives
- Implemented a major process water cooling optimization project.
- Involved adding heat exchangers and a cooling tower to the existing cooling system.
- A new DDC controller was also installed, which directs water through either the cooling towers or the heat exchangers to achieve the desired temperature.
Benefits
Annual Energy Savings: 1.068 GWh
Annual Cost Savings: $55,000
Not only does the new system significantly reduce energy use, it also increased productivity, improved IPEX's environmental performance and minimized the need for additional water from the municipality.
Now there is increased line capacity and adequate cooling for future plant expansion.
