As of 2021, the US industrial sector is responsible for a third of the country's energy consumption, accounting for over $100 billion in fossil fuels alone. As industrial processes demand more energy, manufacturers have come to the aid of industry with energy saving products to reduce consumption and save money down the line.

Energy Efficiency Chart

Often, the best way to save money for an existing process isn't to invest in expensive machinery that requires a complete system rebuild. Rather, monitoring the system more efficiently can expose vulnerabilities or energy losses like heat bleed or failing components.

The adage goes 'what gets measured gets managed,' and as we move into the latter part of 2021 and more companies embrace energy efficiency and environmental concerns, this will only continue to become a more important cost factor for most, if not all industrial businesses.

Carotek highlights products from manufacturers that recognize the importance of energy efficiency in all industrial processes. These manufacturers’ design innovations offer a number of ways to take advantage of energy savings.

Vaisala has expanded its portfolio to solve for energy efficiency in raw material processing, steam, electricity and much more. Their in-line process refractometers (formerly K-Patents) continuously monitor liquid concentration to ensure manufacturing quality, increase equipment uptime and maintain accurate density measurements. With a wide range of applications in various industries, such as food and beverage, pulp and paper, pharmaceuticals and chemicals, Vaisala process refractometers use refractive index which can be controlled and tuned for minimal energy consumption, while ensuring process reliability and product quality.

When applied to unique, industry-specific applications, these instruments can significantly reduce resource and maintenance requirements. For instance, food manufacturers can more closely monitor energy-intensive operations like evaporation or spray drying to minimize the time and materials needed to complete the process. Similarly, pulp mills can install a refractometer to measure total dissolved solids going into a recovery boiler to confirm dry solids liquor content is of a quality to maximize energy production. As manufacturers seek to develop greater insight into their energy consumption and creation, Vaisala process refractometers offer a continuous monitoring solution that is free from regular maintenance and calibration requirements while maintaining stability and reliability.
