System Assessments
As the Best Practices Magazines celebrate their twentieth anniversary, we wanted to take a moment to reflect on the remarkable system efficiency gains achieved since our first issue. We also wanted to give subscribers a peek at what the next decades might bring. To do this, we asked a hand-selected list of original equipment manufacturers, independent compressed air system sales and service companies, manufacturing plants and independent system auditors to share their thoughts, highlighting the changes they’ve seen over the past 20 years, then predicting what the next 20 years will bring.
Controlling cooling water flow is a critical element of high-performance cooling systems. Fortunately, pressure is a straightforward measurement that can be used as a cost-effective control input for flow control systems. Proper interpretation of pressure readings is required for accurate control at desired rates. This article covers pressure reading methods, control strategies and practical tips.

Thermal energy storage (TES) is a vital tool for managing energy consumption. By storing thermal energy for later use, TES systems help reduce peak demand on the power grid, lower energy costs and contribute to sustainability goals. This article explores how TES systems work, their economic benefits and their role in supporting a more resilient and sustainable energy infrastructure.

Heat pumps have found growing popularity as a high-efficiency solution for cooling and heating. With greater public awareness and organizational emphasis on sustainability, these systems are a viable upgrade to a wide range of processes, from residential climate control to industrial heating and cooling applications. The flexible functionality of heat pumps – namely their ability to reverse the traditional vapor-compression cycle – offers them significant advantages over refrigerant and combustion-based systems.

Machine cooling high temperature problems are unfortunately all-too common in industrial plants. While the initial suspect is always the heat exchanger, there are several other factors that can be the underlying cause. Important steps can be taken to minimize the potential for heat exchanger fouling, but when problems do occur, careful examination of the machine and the system can help identify the problem efficiently and with minimal wasted effort.

The initial reason the modular concept took hold was a frequent lack of space when it came time to replace a large chiller. Often, these chillers were installed in a confined mechanical room in the basement at the beginning of construction, and the building was then built around it. There was barely enough room to get people to the chiller for maintenance, let alone replacing the chiller itself.

Using a combination of predictive analysis and historical information helps companies make sound decisions relating to CUP operations. Ever-changing loads, weather and utility prices combine with hundreds of components that all impact energy efficiency. While previous strategies focused on individualized equipment efficiency and automation, CUP optimization considers the complete system.
