HORIZONTAL ELECTRIC STORAGE HEATERS
Options
n Tank Linings
CEMENT – A special formulation of cement providing excellent
corrosion protection. Available on 200-gallon and larger tanks.
EPOXY – A solventless two component epoxy lining applied to a
minimum ten-mil (.010”) dry thickness. Available on 200-gallon
and larger tanks.
n GOLDENROD
®
ELEMENTS – Available with Optional Goldenrod
®
Elements - All DVE/DHE models are available with the Goldenrod
®
24K gold plated elements (patent pending). Goldenrod
®
Elements
provide long-life and five times the scaling resistance of standard
incoloy elements. Goldenrod
®
Elements carry a three-year
warranty against failure due to scale buildup.
n SPECIAL CONSTRUCTION – Silicon Bronze Vessels are available for
special applications or very corrosive water conditions. Consult
factory for specific sizes.
n STAINLESS STEEL VESSELS – Are available for deionized water.
Built with stainless steel under rules of Section IV of the ASME
Boiler and Pressure Vessel Code for operation on deionized water
having a minimum specific resistivity of 10 megohm/cm.
n 150 OR 160 PSI WORKING PRESSURE – Must be specified at time
of order.
Other Optional Features
n TEMPERATURE AND PRESSURE RELIEF VALVES – For working
pressures other than standard; consult factory.
n HORIZONTAL OR VERTICAL – See specifications, most gallon
capacities may be obtained in vertical or horizontal construction.
n CIRCULATING PUMP PACKAGE – Circulating pump and piping
sized to turn over entire storage capacity of tank once each hour.
Recommended to optimize available water at temperature in
horizontal tanks particularly where low draw conditions
are anticipated.
n OPTIONAL INTERNATIONAL VOLTAGES – 380 and 415 volts
three-phase.
n 3-1/2” DIAL-TYPE PRESSURE GAUGE – Factory-installed.
n 3-1/2” DIAL-TYPE TEMPERATURE GAUGE – Factory-installed.
n 11” x 15” MANHOLE – Available as option on tanks 700 gallons
or smaller.
Control Options
n COPPER TUBE TANK HEATER – Double wall copper tube tank
heaters are designed for heating potable water with both
potable or non-potable liquids or steam, and are specifically
engineered for installation in models DVE and DHE for dual-
energy applications. Tank heaters have a positive fail-safe means
of leak detection in the event of either tube failure to prevent
mixture of heating medium and potable water. Singlewall heat
exchangers are also available.
n TERMINAL BLOCKS – Allows for remote connection to building
demand limiter or other functions.
n AUTOMATIC RESET HIGH LIMIT – A control that in the event of
high temperature, interrupts power, de-energizing elements,
automatic reset. (Standard with modulating step control).
n INDICATING LIGHTS – Denotes heating stage(s) in operation. Up
to one light per contactor is available.
n OVERRIDE SWITCHES – A simple means of load control allows all
or part of unit input to be controlled manually. Up to one switch
per contactor is available
n SAFETY DOOR INTERLOCK – Prevents opening of control panel
door when heater power supply is on. NOTE: Once door is
opened heater may be energized if necessary for service
diagnosis.
n SHUNT TRIP CIRCUIT BREAKER – A safety device (circuit breaker)
which disconnects power to heater in the event of over-current,
high temperature or low water level, breaker must be
manually reset.
n CIRCUIT BREAKER – A safety device which disconnects power to
the heater in the event of overcurrent.
