How DSI Works
Direct Steam Injection Heating
Direct Steam Injection (DSI) heaters are industrial devices that efficiently heat liquids by directly injecting steam into the fluid. Unlike traditional heat exchangers, DSI heaters eliminate the need for separate steam chambers and maximize energy transfer with nearly 100% thermal efficiency. They provide precise temperature control, ensuring consistent heating for various industrial applications like food and beverage, chemical processing, and wastewater treatment. DSI heaters offer significant operational savings by minimizing energy waste and reducing maintenance needs. Additionally, their compact design requires minimal space, making them a flexible and reliable heating solution.
Benefits of Direct Steam Injection
They consistently outperform heat exchangers and other fluid heating systems since each Hydroheater is created in response to your input. Hydro-Thermal listens to your needs and custom designs a solution to meet the specific requirements of your industry, company, and application.
Hydro-Thermal’s heaters are 100% energy efficient. They utilize both the latent and sensible heat available, ultimately resulting in a 20-30% energy savings. Internally modulated steam also means responsive and precise temperature control (within ±1°F), instantaneous temperature attainment, and rapid heat transfer.
Hydro-Thermal’s simple design and minimal moving parts mean you will spend little time on maintenance. The sonic velocity creates a self-cleaning action that eliminates process interruptions and downtime. Plugging and fouling will be things of the past and maintenance will be something that only needs to happen once a year. In fact, the Hydroheaters patented internal modulation is so smooth it eliminates hammer and vibration. It’s so quiet; you might not know it’s there.
A Hydroheater will save you time, money, and frustration. Our system responds immediately to changes in set point, flow rate, pressure variation and process upsets. Through this, performance can be optimized under varying conditions, production can be maximized, and disruptions virtually eliminated. Also, our small footprint saves you up to ¾ of your space, freeing up production floor space. Our system also eliminates need for condensate return systems.

The savings start immediately when you purchase a Hydroheater. It is quick and easy to install. Over the years it is in service your properly maintained Hydroheater will continue to see the same high levels of performance and efficiency. With annual maintenance, your Hydroheater will operate safely and precisely for many, many years. Customers who maintain their heaters properly often have their Hydroheater in service for decades. Our 100% performance warranty assures your Hydro-Thermal heater’s long life.
Internally modulated steam means responsive and precise temperature control (within ±1°F), instantaneous temperature attainment, and rapid heat transfer. This saves energy by heating fluids to exact temperature, allowing set points to be reduced, which decreases energy demand and can result in improved product quality.
The Hydroheater is robust, reliable, and is designed to battle high abrasive fluids, minimize hammering and vibration while heating to the desired temperature. Hydro-Thermal’s heaters are cast, leading to longer part life & rigidity. For highly abrasive environments, metallurgies can be modified. Otherwise, additional weld overlays and/or the use of abrasive resistant materials may be recommended. For specific requirements for your application, please contact Hydro-Thermal directly.
Eliminate the need for acid baths and costly monthly shutdowns. Some steam heaters foul and scale because of their inner workings and spring parts causing them to clog requiring frequent acid baths. This reduces productivity and increases maintenance costs. Our Hydroheater solves this problem because it has a unique steam plug and diffuser allowing it to inject precise amounts of steam at sonic velocity via choked flow causing a self-cleaning action. When properly sized for the process conditions and the application, our energy efficient steam heater virtually eliminates scaling and fouling, making it the most reliable process heater on the market.
