It is our core belief that cooling systems, unlike any other plant utility, have exceptional leverage opportunities to improve their performance and operating costs.

Every day, ISG clients see a multiple improvements within their systems including: 

  • Improved process stability

  • Enhanced reliability

  • Lower ongoing maintenance costs

  • Reduced capital costs from extended equipment lives

  • Significant energy savings

These benefits are achieved through a combination of design and operational improvements, for example: 

  • Leveraging wet-bulb tower setpoint adjustment to capture seasonal system efficiency improvements and save tower fan system wear

  • Improving pump loop balancing and flow control to eliminate wasted circulation and energy use while simultaneously improving pressure control and cooling effectiveness

  • Implementing chiller equipment upgrades, advanced control strategies, split temperature tier cooling, and, where possible, water-side economizers (“free cooling”) to improve heat rejection efficiency as well as extending the life of the cooling equipment

  • Redundant equipment operating strategies for superior “no-blink” process reliability

  • Variable speed drive applications on all driven equipment for precise operation and lower ongoing maintenance costs

Our system improvements often pay for themselves through energy savings alone and readily qualify for efficiency incentives where offered.  While this was a major driver in ISG’s initial focus on cooling systems, we learned through the years that energy efficiency per-se isn’t nearly as important to manufacturers as process stability and reliability.  Fortunately we have found that the same system improvements that support those two overriding requirements, if intelligently implemented, also enable the significant other benefits noted for equipment maintenance and capital costs – all paid for substantially with indisputable energy savings.
