RCSX Instantaneous Steam-to-Water Heater

High-Temperature Blend-down System

Designed for Buildings with Re-circulating Domestic Water Loops

CSX single-exchanger models range in output from 15 to 75gpm of 140ºF water with 15 psi steam. Packaged dual-exchanger systems are available.

Fixed-temperature valves (tamper-proof) are available to provide 120ºF, 140ºF or 160ºF outlet water to within ± 5 ºF. Valve failure results in cold water ﬂ ow.

Exchanger is passivated 316L stainless steel with corrugated, helical tubing and a counter-

ﬂow design for low ﬂ oor space requirements. Water is in the shell and steam in the tubes.

High-temperature blend-down is an approach to domestic water heating where potable water is initially heated by a steam heat exchanger to 220ºF to 250ºF and then is blended with cold water through a mixing valve to achieve the required outlet tempera- ture. The approach avoids modulating steam to control water temperature and instead relies on the modulation of ﬂ ows of cold and hot water.

CSX Compared to Competitive Blend-Down Water Heaters with Building Re-Circulation

Greater Temperature Accuracy - dual control valves

CSX controls the blending of hot and cold water through two separate ﬁ xed-temperature mixing valves downstream of the heat exchanger. With a building re-circualtion loop, both valves are always blending.

Greater Safety - high-limit shutdown system

CSX is equipped with a high-temperature shutoff device on the hot water piping. Thermostats monitor the downstream side of both blending valves. A solenoid valve shuts off ﬂow from the heat exchanger if water temperatures climb above either high-limit threshold.

True Clean-in-Place Capability

Unlike competitive designs that require the breaking of piping connections or the removal of blending valves to access the waterside of the heat exchanger, CSX provides two readily accessible CIP threaded ﬁ ttings. All piping remains intack during cleaning.

Variable “Cold” Water Temperature is No Problem

The dual CSX blending valves respond seamlessly to variable temperature and ﬂ ow at the cold inlet port and produce water within 5 degrees of the system’s setpoint temperature.

Competitive designs use a blending valve that responds to ﬂow as the only variable input. Using this type of valve requires the cold water temperature at the valve inlet to remain constant. With a building recir- culating loop, water at the valve’s cold inlet can range from 40ºF to 110ºF. The valve has no internal means to adjust to this variable and can miss the outlet tempera- ture target by a wide margin. Without additional down- stream blending valves, over- or under-temperature water can enter the domestic water system.
