Advantages of Direct Steam Injection Heating

1. Exceptional energy savings compared to heat exchangers and spargers direct contact steam heating is nearly 100% energy efficient. It uses all of the sensible and latent steam energy to directly heat process water or fluid. This aspect has saved Hydro-Thermal customers thousands of dollars in energy costs alone. Last year, an international steel mill replaced an energy hog hot water heater and sparging system with a Hydroheater^® and immediately saved $56,000 per month on their continuous annealing line.

2. Precise temperature control often temperature set-point is critical to the process or the utility task at hand. Hydroheaters maintain precise temperature control using industrial steam.

   • The bleaching process in pulp & paper mills requires optimal temperatures to ensure paper brightness and to reduce chemical usage saving volatile emissions and money. Directly mixing steam in this process using a Hydroheater keeps tight temperature control and the quality of the product.

   • Temperature of wash-down stations in the food industry is critical to food safety. Hot water supplied through a direct steam injection heater maintains exacting temperatures and supplies hot water on demand.

   • Starch cook-out in the ethanol process depends on exact temperatures for optimal shear and higher ethanol yields. The Hydro-Thermal Jetcooker provides this control.

3. Low maintenance Heat exchangers often experience burn on and loose efficiency. Cleaning them can shut-down a process for hours or days.  Some other steam heaters foul and scale and must be taken off-line for acid baths, again, shutting down the process line.

   • Hydro-Thermal steam injection heaters have a patented self-cleaning feature so they never foul or scale with product burn on or hard water sediment. When properly maintained, Hydroheaters can perform at optimal levels, never causing an un-scheduled shut-down.

4. Instant temperature rise Steam mixes with the water or process fluid inside the valve at very high, often sonic, velocity causing an almost instantaneous temperature attainment. Paper mills have saved enormous amounts of time getting to set-point temperature faster than using heat exchangers or sparging systems.

5. Space savings Heat exchangers and sparging tanks can take up an enormous amount of floor space and may even need double the footprint for cleaning and maintenance clearance. Hydroheaters are small in comparison, fitting into the pipeline and freeing up production floor space.

6. Quiet operation Many heat exchangers and other steam injection valves can create high decibel noise and even shake causing damage to process piping and other equipment. Due to patented internal modulation (valve mixing), the Hydroheater maintains a quiet hammer-free operation.

Unlike heat exchangers or spargers, the Hydroheater is designed only for your process conditions and unique application. We need to know a few things about your conditions, such as temperature range, steam pressure, and flow rates to size a heater specifically for you. When you click on our application data sheet and fill in the information, we will contact you within one business day. After an initial conversation with a sales representative or one of our engineers, we will then provide you with a custom quote for the Hydroheater best suited for your process.
