Hard water issues, loss of production, plant shutdowns, and damage to your reputation are a few of the many consequences of not having water at critical temperatures exactly when you need it. 

If you depend on unlimited hot water at precise temperatures and required flow rates, we have your solution. Not only will you have all the hot water you need, but our heaters are self-cleaning and need far less maintenance and upkeep than any heat exchanger. Our solutions will replace large tanks, spargers or heat exchangers with a much smaller footprint and far greater energy efficiency.

Hydro-Thermal’s patented heating system works by mixing steam and process liquids completely while delivering consistent temperature and instantaneous heating. For more information on our advanced direct steam injection technology, click here.

Heating products utilizing direct steam injection

The type of heater you need is dependent on how it will be used. No matter what your application, Hydro-Thermal has the solution for every application involving water heating.

All of our heaters share unique benefits, including internal modulation, self cleaning ability and rugged design and construction.

Here is what makes each solution unique:

EZ Heater/EZ Skid System

The EZ Heater is designed specifically for water heating and is the driving force behind the EZ Skid System. The EZ Heater and EZ Skid System share the unique benefits of our other heaters, including internal modulation and self cleaning ability.

  • For more information on the NOH, please click here.


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.
