Steam/Water Heaters Steam/water heaters are typically classified as instantaneous, semi-instantaneous and tank-type. Temperature control can be defined as either feed-forward or feedback.

Feedback systems are error-driven and rely upon an outlet or downstream thermostatic temperature-sensing device to detect a temperature change requirement and then modulate the steam to effect the heat exchange in an attempt to recover the heater set-point. Feedback systems are reactive, and a significant concern is their speed of response to system and application temperature control requirements.

Tank-Type Steam/Water Heaters (feedback)Tank-type steam/water heaters typically include a temperature sensing element or coil immersed in a storage vessel with a separate, remote steam control valve. As a function of their integral and often significant storage capability, the poor response times often associated with the relationship of temperature-sensing device and steam control valve are less of an issue.

Tank-Type Steam/Water Heaters are a less attractive option for the following reasons:•Theyconsumealargeamountofvaluablemechanical-

room real estate.•Identifiedasamplificationandcolonizationpointsfor

•Separatesteamcontrolvalves,requiresongoingmaintenance.

•Thermostaticelement/sensorshaveatendencytowearand eventually rupture under a heavy cycle load.

•Theyareslowtorecoverandmayrunoutofhotwater during peak load periods.

Tankless Instantaneous Steam/Water Heaters (feedback)Tankless instantaneous steam/water heaters, often referred to as shell and tube heat exchangers, do not include hot water storage capacity. These models will rely upon either an outlet or downstream temperature-sensing element with a separate steam control valve.

Tankless Instantaneous Steam/Water Heaters are a less attractive option for the following reasons:•Lagtimefrommessage(thermostat)toaction(controlvalve)createsthermallagandaresultingtemperatureswing.

•Modulatingsteamsupplycancausecondensateevacuation issues, resulting in damage from water hammer and tube bundle corrosion.

•Acyclingphenomenonduringlow-orno-demandperiodswill cause premature wear to the thermostatic element. Thermostats typically fail in an open position, making overheated, scald-temperature water available to the system.

High-maintenance feedback systems with large storage tank may leak, corrode or rupture a thermostatic control.

Feedback instantaneous systems may suffer from lag time, tube bundle corrosion and problems with thermostatic element deterioration.

Semi-Instantaneous Steam/Water Heaters (feedback)Semi-instantaneous steam/water heaters typically include lower-capacity storage, with an integral steam control valve to deliver the heat exchange through an internally positioned element or coil.

Flo-Rite-Temp® instantaneous steam/water heaters can easily do the work of a storage tank unit many times its size—at lower installed cost and with minimum maintenance. Even the largest capacity Flo-Rite-Temp® requires only 13.5 ft2 (4.1 m2) of floor space.

Semi-instantaneous water heaters are subject to poor recovery time at peak demand, inadequate low-flow temperature control and shorter service life.

The Flo-Rite-Temp® instantaneous Steam/Water heater has a unique feed forward design which features a differential pressure diaphragm actuated mixing unit integral to a shell and tube heat exchanger.

The Flo-Rite-Temp® mixing unit manages the water flow through the heat exchanger based upon downstream hot water demand and eliminates the requirement for a modulating steam control valve.

Operating on constant low pressure (2-15PSI) steam, the Flo-Rite-Temp® mixing unit supplies water to the heat exchanger where it is overheated and then returned to the mixing unit for proportional re-mixing with cold water to a pre-set outlet temperature.

Speed of responseThe differential pressure diaphragm within the mixing unit rapidly responds to a change in system demand and significantly reduces the lag times typically associated with feed back/modulating steam control valve systems.

Failure SafeThe Flo-Rite-Temp® mixing units diaphragm actuated design can be described as “failure safe” because in the event of a diaphragm failure the mixing unit will fail with a cold bias and will not allow hot water to exit the heat exchanger.

Outlet temperature set-pointadjustment

Automatic air venting

Integral diaphragm actuated mixing unit eliminates intermediate pipework

Scaling and fouling is reduced because the internal controlvalves/seats and moving partsare only exposed to cold water

Differential pressure diaphragm rapidly responds to a change in system demand and significantly reduced the lag time



Temperature Control and User SafetyCapable of controlling outlet temperatures +/- 4F, this principal of operation offers the additional relevant benefit of reducing the waterborne bacterial content of the water during the overheating process. In addition, with no water storage requirement, Flo-Rite-Temp® water heaters are a sensible selection as a component of a broader system design initiative for Legionella risk reduction.

Ease of MaintenanceAccessible “non helical” admiralty brass straight tubes inside the carbon steel shell available mechanical cleaning and visual inspection. Non modulating constant steam pressure ensures condensate drainage and removes the potential for water hammer damage and corrosion. There in no steam control valve to maintain and typically no supplemental condensate return equipment required.

Ease of InstallationNo storage tank, small footprint, access via a standard doorway and pre-piped packaged solutions reduce installation time, space and expenditure.

Straight tubes for easy cleaning and easy removal

Floating head reduces tube stress

Removable tube bundle cover/cap eases maintenance inspection and mechanical cleaning

Constant steam pressure drains condensate which reduces tube bundle corrosion and water hammer issues.

The DW (double wall) version of the Flo-Rite-Temp® instantaneous water heater uses a double-wall tube to provide positive separation of the steam and water in the heat exchanger. The area between the walls of the tubes vents to atmosphere so you can detect tube failure without cross-contaminating either the steam or water. The Flo-Rite-Temp® DW is well suited for all hot water applications where steam is available and plumbing codes or safety requirements prevent the heating medium and the potable water supply from being cross-contaminated.

Flo-Rite-Temp® Instantaneous Steam/Water Heater Stainless Steel

12


The Flo-Rite-Temp® SS is a compact, steam to water, instantaneous water heater with all wetted metal parts of type 316 stainless steel. Because of its construction materials, this heater is well-suited for heating most corrosive liquids, such as demineralized, deionized or reverse osmosis water commonly used by manufacturers of electronic equipment, pharmaceutical and food.

Features• Feed-forwardcontrolprovidesaccuratetemperature

control on demand even when demand fluctuates abruptly.• Feed-forward operation ensures that the heater will fail

safely in the closed (cold) position to prevent overheating.• Straight, non-U-bend tube bundle with removable end

cover provides for easy tube cleaning along with the capability to visually inspect all tubes.

• Constant steam pressure on heat exchanger at all times means positive condensate evacuation, avoiding damage to the exchanger due to water hammer.

• Heavy duty 5/8’’ tubes of 16 gauge 316L stainless steel ensure long life and maintainability backed up by a 10-year tube bundle warranty against workmanship and material defects.

• Control valve is mounted integral to the heat exchanger, thus eliminating intermediate piping leaks.

Flo-Rite-Temp® water heaters are available in four base models each sized with a prefix that denotes the shell size in inches (4”, 5”, 6” and 8”) and a suffix that denotes the flow rate at a 100°F temperature rise (15 gpm, 35 gpm,65 gpm and 120 gpm).

Each Flo-Rite-Temp® model’s heat exchanger is single wall construction as standard but is optionally available as a Double Wall (suffix DW).

Each Flo-Rite-Temp® model is supplied as a shell and tube style heat exchanger with integral mixing valve/head and is also available as a pre-piped “Packaged Solution” (suffix P-P).

Flo-Rite-Temp® Packaged Solutions are also available with a second heater (parallel, suffix PP-P) and third heater (triplex, suffix Trip) for increased flow capacity, redundant installation or both.

Flo-Rite-Temp® Packaged Solutions are supplied for either point of use “dead-leg” applications or can be factory piped for a recirculating hot water system in either a standard configuration with a thermostatic diverting valve (suffix R) or as a Tempered Water system (suffix TW).

Flo-Rite-Temp® Packaged Solutions designated as Tempered Water Systems (TW) include an on board Digital Mixing Center (suffix DMC) which features DRV 80 “The Big Brain®”

Higher flow Flo-Rite-Temp® Packaged Solutions and Systems designed with built-in redundancy can include two DRV 80. The model code (DMC) always includes a trailing suffix which identifies the number of Digital Mixing Valves (DMC 1, DMC 2, etc.) The Digital Mixing Center can be assembled with a recirculation pump with a “2” in the model number following the DMC/(DMC 12 only).

Flo-Rite-Temp® Packaged Solutions fitted as DMC include a 4-20mA connection as standard on the DRV80. The 4-20mA connection provides the capability to access and transmit the water temperature output from the valves integral Mixed Outlet Water Sensor and allows Remote Set Point adjustment capability for “plug and play” system communication via PC, LAN or resident Building Automation System. BrainScan® a Digital Hot Water Management System Console can be added by adding the suffix BrainScan with a hyphen. Flo-Rite-Temp® packaged systems fitted as DMC can connect BrainScan® directly to the serial port on the DRV 80.

When Integrated accordingly BrainScan® provides 3 levels of system interrogation options (see page 28) and is configured for most building automation systems which use BacNet™, LonWorks™ and ModBus protocols. BrainScan® also avails LAN and Web Browser connectivity options.
