Actuator Options Available

Hydro-Thermal's heaters utilize a Fisher reverse-acting diaphragm actuator (“fail close”). Generally coupled with a filter/regulator and a Fisher DVC 2000 or a DVC 6200 positioner that converts a 4-20 mA DC input signal to pneumatic output signal to the actuator. For high vibration applications remote mount positioners are available. Alternative positioners are available depending on unique processing conditions or upon request. Please contact Hydro-Thermal for more details.

Applications for Paper Production

Direct steam injection heating utilizing the Hydroheater

No matter what your industry or application Hydro-Thermal’s heating solutions will assure you saving energy costs, reducing maintenance down-time, and more.

With instantaneous heating when you need it, our products are ideal for anywhere maintaining a precise temperature is critical. Our most popular heating applications include:

WHITEWATER CHEST OR SILO HEATING:

Venturi pumping effect of our Hydroheater design allows for simple installation, utilizing inline heating to avoid steam hammer, tank damage, and energy losses associated with sparging.
Whitewater or any process water used on the paper machine, can be heated by Hydro-Thermal technology. Hydro-Thermal can help you maintain or increase water temperature. Achieving higher water temperature (ideally 120-140˚F) can improve drainage on the wet end of the paper machine which ultimately increases machine speed. In addition, higher temperatures can improve water removal in the press section of the machine, and reduces bacterial growth.

WHITEWATER PROCESS STREAM HEATING (NON-VENTURI PUMPING)

Effectively mix large quantities of steam for rapid temperature increase of entire whitewater system, including header overflow, screen rejects, or seal pit return.
Whitewater or any process water used on the paper machine, can be heated by Hydro-Thermal technology. Hydro-Thermal can help you maintain or increase water temperature. Achieving higher water temperature (ideally 120-140˚F) can improve drainage on the wet end of the paper machine which ultimately increases machine speed. In addition, higher temperatures can improve water removal in the press section of the machine, and reduces bacterial growth.

OTHER FRESH WATER USES AROUND WET END

Improve production efficiency and sheet quality. Felt and wire showers benefit from tempered water for improved cleaning and elimination of temperature stratification. Head box and other roll showers benefit from heating/tempering water to match whitewater temperature. By having uniform temperature that matches whitewater temperature, there is a consistent temperature profile on the machine. In turn, the machine runs more consistently which increases production quality.

REPULPER/RECYCLED FIBER HEATING

Reduce pulping time or eliminate the need to sparge into pulpers during operation by preheating fill water for repulpers. Improved contaminant removal and enhanced dewatering are also benefits.
Most repulpers require heat to break up bails and wastepaper. Preheating is more efficient, because it will improve repulping time while avoiding direct sparging into the repulper. Water heating is at the core of Hydro-Thermal’s applications, because precise and consistent temperature is a crucial part of manufacturing especially in the processing of paper.

JETCOOKER™ STARCH COOKING

Many types of starches can be processed with inline cooking for size press, wet end, and coating starches/slurries. Complete systems can incorporate automated flush and preheat cycles, cooked and final starch solids control, hold tube retention time, and back pressure control.
Hydro-Thermal’s technology allows paper manufacturers to use continuous or semi-batch processing compared to the traditionally used batch cooking. Exact temperature produces a quality starch cook that provides uniform and consistent results. Ultimately, sheet properties, coating quality, and surface quality are all improved.
