Better than any other DSI method...

ATTEC^® is easy to CIP...
Many direct steam injection heaters incorporate a sparger in their design, making CIP difficult. Hydroheater's simple streamlined design (with no sparger) makes it easy to clean in place.

ATTEC offers smoother operation without fouling...
With externally modulated direct steam injection heaters, steam pressure and velocity at the point of injection can vary, causing hammering, scaling, and plugging. Internally modulated, Hydroheater^® ensures constant steam pressure and velocity producing a uniformly heated product without process problems -- even with highly viscous slurries.

ATTEC offers better support...
Beware of off-the-rack solutions to unique process challenges. Components should be integrated into an optimal systems solution, rather than simply pieced together. Designed to optimize the Hydroheater's performance, every ATTEC system is engineered, built, and installed to the individual specifications of your process.

ATTEC eliminates "burn on", improving quality while reducing maintenance...
Inside a jacketed kettle, product can "burn on", causing loss of product, contamination, and heat transfer fouling. Those problems can in turn result in lower product quality, increased processing time, higher energy consumption, and more maintenance. The Hydroheater at the heart of the ATTEC system works by injecting steam directly into the product -- there are no heat transfer barriers onto which product can "burn on".

ATTEC heats more consistently...
Steam spargers in a kettle can produce hot spots that overcook product. Hydroheater has no sparger, and no resultant hot spots. Its combining tube can be adjusted to ensure steam contact with all slurry granules for complete, even heating.

ATTEC is more energy efficient...
With kettles, heat can be lost as steam escapes from the surface. Hydroheater is 100% energy efficient, using only the steam necessary to properly heat the product.
