ZESTOS: Transforming Steam Boiler Efficiency and Sustainability

At ZESTOS, we believe that true innovation goes beyond simply improving equipment — it means creating solutions that protect your investment, reduce your costs, and help safeguard the environment.

Based in the United States and proudly serving customers nationwide, ZESTOS is a pioneering company specializing in advanced boiler feedwater systems designed to dramatically improve steam boiler performance. Our patented ZESTOS system eliminates destructive dissolved gases such as oxygen and carbon dioxide from boiler feedwater, addressing two of the most aggressive causes of corrosion and scaling in boiler operations.

Oxygen is known to corrode boiler metal at a rate ten times faster than carbon dioxide. When these gases combine, the corrosion rate increases up to 40 times, severely threatening boiler integrity and service life. The ZESTOS system solves this problem at its core by pre-boiling the feedwater to drive out these harmful gases before they enter the boiler, providing cleaner, stronger, and hotter water to the system. This approach not only extends boiler lifespan but also reduces chemical treatments, maintenance needs, and downtime.

Our system is designed to handle high temperatures up to 248°F (120°C) and integrates robust multi-stage Grundfos pumps to ensure reliable and efficient operation. We use precise microchip controls to manage water levels and temperatures accurately, preventing unnecessary water waste and maximizing energy recovery.

ZESTOS also helps businesses reuse valuable energy that would otherwise be lost through steam venting, turning waste into an asset. As a result, customers can expect lower fuel costs, higher energy efficiency, and a more sustainable operation overall.

Whether you operate a dry cleaning plant, a laundry facility, a food processing plant, or any other operation that depends on steam boilers, ZESTOS offers a proven solution that enhances both your economic and environmental performance. Our mission is to empower our customers to achieve superior boiler performance, minimize operational risks, and contribute to a cleaner, more efficient future.

At ZESTOS, we pride ourselves on combining engineering expertise with a deep commitment to customer satisfaction. From initial consultation to installation and ongoing support, our dedicated team is here to ensure you get the most value from your investment.
