Hydron™ Sanitary Hydroheater Applications & Benefits

How Does Our 3-A Certified Sanitary Hydroheater Work?

Hydro-Thermal’s Hydron Sanitary Hydroheater is a perfect fit for applications in the food & beverage and pharmaceutical industries. The Hydron is 3-A certified making it the heater of choice for processes that require fast and precise temperature control without any degradation in quality.

The Hydron Sanitary Hydroheater is a sophisticated heat transfer device capable of 100% heat transfer efficiency and precise temperature control. It employs a unique internal geometry to control the steam injection process. A variable area nozzle/stem plug is used to precisely regulate steam flow. The steam condenses and disperses into the liquid so quickly that hammering and vibration often experienced with less sophisticated heaters are virtually eliminated.

The high steam velocity turns it into a self-cleaning machine, ensuring that internal surfaces will not plug or foul regardless of the product being heated.
