The Perfect Temperature, Every Time

hot water skid that delivers perfect water temperature every time

Are you looking for an efficient and cost-effective method for heating water?  Whether a central hot water system, a hose station, a tank or a CIP system, the right heat exchanger can provide on-demand hot water at a precise temperature with no energy loss and within a small footprint.

Hydro-Thermal’s EZ heater systems use Direct Steam Injection (DSI) heat exchangers for perfect water temperature control.  DSI heat exchangers are essentially 100% efficient, delivering up to 25% energy savings and achieving a rapid ROI.  They are easy to install and are simple to operate.  Hydro-Thermal heaters have a strong reputation for best-in-class reliability and minimal unplanned maintenance.  The EZ Heater can maintain +/- 1F precision, enabling consistent process temperatures and production capabilities. This gives you efficient and cost effective heat control from your heat exchanger and the perfect water temperature.

How does it work?

Internal Modulation
This unique patented design assures precise steam control and produces predictable results based on the position of the stem plug. A variable-area steam nozzle meters steam flow at the point where steam and liquid first contact and mix. This technique eliminates the need for an external steam control valve and provide efficient heating control to your process.

Choked Flow
Choked flow is the phenomenon of accelerating a vapor to maximum velocity by creating a pressure differential through an engineered nozzle. Establishing choked flow precisely controls the heating of the liquid by metering the steam flow. Because of this metered flow, your steam is used efficiently; providing effective heat control to your water.
