MODEL HXS:  Heat Exchange / Transfer Station / DI Water Heater

(click to enlarge photo)

Key Benefits

  • Recovers thermal energy in drain-bound water
  • Evacuates water to a remote location
  • Saves energy
  • Provides enough flow and pressure to treat for heavy metals with the addition of HMR tanks
  • Minimizes capital investment

A tremendous amount of thermal energy is required to increase ambient water to an acceptable final rinse temperature (140 °F).  Typically, a dedicated, high capacity water heater is required.  If the final rinse uses deionized water, the heater must be made of a compatible material, such as stainless steel, which means even greater expense.

In an open loop system, cleaner wastewater is delivered to a drain.  The drain bound water is usually near the set point temperature of the recirculating tank (140 °F).  The REsys HXS Heat Exchange System can be employed to extract valuable heat energy from the wastewater and “recover” to heat incoming water.  Heat transfer is not 100%, therefore a booster heater is included to achieve the desired final rinse temperature.  This turnkey system also has a recirculation pump, buffer tank and particulate filter – all in a compact footprint.

Utilizing the HXS greatly reduces the amount of thermal energy required to heat the incoming final rinse and make-up water.  The amount of thermal energy recycled translates into substantially lower operating costs.  In a typical, 2000-hour-per-year production environment, the HXS can save thousands of dollars in energy costs.  Contact REsys for information on cost modeling.  For applications where water volumes can not justify heat exchange we offer in-line DI water heaters.
