When companies prioritize saving energy, they reduce their operating costs and therefore increase their competitiveness. But many companies are still highly unaware of how much energy they are actually using. This is where Endress+Hauser can help by implementing utility management solutions! There are so many potential areas to save in the five major utilities: steam, compressed air, heating, cooling and industrial gases.
In this series of blog posts, we will cover the five utilities where companies can save energy and money, specifically within the heavy industries which include Chemical, Oil & Gas and Power & Energy. In this first post, we’ll dive into steam and compressed air.
Steam- Monitoring steam systems efficiency and minimizing fuel consumption
In heavy industries, heating systems are used on a grand scale- for heating the process or for power generation in turbines and for sterilization or for cleaning purposes. These days, steam system management covers a whole lot more than checking water level, conductivity, pH value, temperature, and pressure in the boiler. Steam boiler systems offer numerous options for saving, re-using and reclaiming energy – all along the steam process (Figure 1).
Whether in generation, distribution, billing or in steam boiler efficiency, Endress+Hauser can provide all the measuring instruments required to optimize your utility management resulting in energy savings. This includes instruments for comprehensive water analysis, allowing you to:
- Monitor specific energy consumption and boiler efficiency
- Share generation costs among multiple cost centers
- Identify and monitor target values based on historic data
- Uncover leaks at valve bodies, connections, pressure regulators, pipe connections and defective steam traps
- Measure steam quality directly in the pipe (wet steam, saturated steam, superheated steam)
- Calculate the gains from energy optimizations
- Maintain control of boiler safety
Steam/Water Analysis System
The quality of water is a matter of central importance in water and steam circuits and as mentioned above, comprehensive water analysis is one-way to improve the quality of your steam systems. Water of insufficient purity can cause corrosion or fouling in your industrial steam boilers and pipes resulting in expensive repairs and replacements. This is where Endress+Hauser’s SWAS solution (Steam/Water Analysis System) can help.
The SWAS solution is for industrial steam generators and is a solution that efficiently monitors the water quality and fits neatly into your system, requiring very little space. It’s comprised of sample preparation, a cation exchanger and a Liquiline transmitter to which the sensors for measuring pH, conductivity and oxygen are connected.

Compressed air- Active reduction of energy loss and leakage
Up to 10% of electricity consumption in industries is used to generate compressed air and 95% of this energy is lost as waste heat in the process. Additionally, up to 30% of the compressed air generated “disappears” due to leakages in the supply network. Nevertheless, financial losses due to inefficient compressed air systems continue to be underestimated, ignored or accepted as a given. This can be mitigated with energy management solutions, allowing you to reliably identify weaknesses and savings potential in your compressed air systems, and permanently monitor the specific energy consumption of compressors
Energy saving opportunities such as minimizing leaks and monitoring filters to cut pressure can be implemented to ensure maximum efficiency in your compressed air systems. Compressed air should ideally be dry because moisture can eventually lead to failure of the compressed air system. Utilizing instruments like the Prowirl F 200 to measure flow can ensure the safety of your airline compressors while monitoring the pressure will keep your energy loss low.
