Steam and water analysis system (SWAS) for power plants
Protect your power plant with highly reliable SWAS solutions
In power plants, water analysis is a crucial factor in keeping the water-steam cycle free of impurities. Boiler feedwater must be monitored to protect turbines, boilers and pipes from build-up and corrosion. Continuous monitoring of water quality is the only way to ensure that the water specification is met, to avoid costly repairs and loss of warranty. Endress+Hauser's flexible SWAS solutions are equipped with state-of-the-art technology for measuring the critical and many other parameters.
Proven in use
in applications in over 100 countries
We already have over 20 years of experience with steam and water analysis systems, which we have been able to incorporate into our current SWAS solutions. Benefit from highest reliability, availability and traceability for your steam and water circuits. We offer a complete parameter basket even for demanding
parameters, Memosens and Liquiline technology for easy sensor calibration and predictive maintenance
functions, plus optimized mounting and minimized sample and cooling water consumption.
All critical parameters in thermal power plants can be safely monitored with Endress+Hauser's steam and water monitoring systems
Electro-deionization (EDI) cation exchanger with electrochemical resin regeneration. This reduces maintenance effort and ensures operational safety, as regular resin replacement is no longer required.

How we can help
With our sophisticated SWAS solutions, you have the quality of your feed water completely under control. Take advantage of highly efficient monitoring of multiple, even complex parameters at a central location. Consistently pure water helps to minimize process downtime and prolong the life of your power plant. You reliably comply with limit values; traceability and secure data management provides proof of water quality at any time. The turnkey systems are easy to commission and operate.
Get standardized or customized solutions for your power application quickly, easily and cost-effectively, equipped with high-tech analysis instrumentation, user-friendly operation and CE marking.
Improve quality management and simplify asset management of your facility with user-friendly documentation tools thanks to Liquiline and Memosens Technology for full calibration traceability and predictive maintenance.
Experience ease and safety in maintenance and process due to Memosens technology and the available electro-deionization cation exchanger, that continuously regenerates the resin, without the use of chemicals, and thus protects process and staff.
Take advantage of seamless system integration into your existing PLCs with various interfaces that provide convenient integration via analog, digital and IIoT connectivity.
Screw the SWAS panel to the wall, connect it to power and water, and off you go – installing and commissioning measuring points couldn't be easier. Remain future-proof, as you receive all parameters and worldwide support from a strong partner.
Heizkraftwerk Zwickau Süd GmbH (HKWZS) has built a new biomass power plant to supply the city of
Zwickau. The plant was equipped with state-of-the-art analytical solution SWAS.
"We are amazed how reliable and low-maintenance the SWAS panel solution is and can fully recommend it to other power plant operators."
