Standard Features

Standard Features

 N/A Advanced Electronic Control
provides precise + or - 1 ºF temperature control, that is ideal for industrial and food service applications where exact temperatures of hot water are needed.
  • Plain Text - Animated icons display detailed operational and diagnostic information. Fault or Alert messages appear if an operational issue occurs.
  • Low Water Cut Off - Factory standard on board water cut-off uses a remote electronic immersion probe to prevent energizing of the elements in the event of low water condition and eliminates dry firing.
  • Progressive Modulating (Only available on units 150 kW or less) - Sizes the input of available elements to match current load conditions. and lead lags element loads to provide long equal wear.
  • Economy Mode Operation (Only available on units 150 kW or less) - Control system automatically lowers the operating set point by a programmed value during user defined time periods. Seven-day clock may be programmed for night set back and or weekend shutdown to reduce operating cost and save money.
  • iCOMM™ Compatible - Units can be monitored from remote locations. Note: Units over 150 kW use analog controls.

Optional Dual-Energy Source Capability

Optional Dual-Energy Source Capability

 N/A Provides emergency back up energy source or winter/summer boiler operation. Can be specified with optional water to water or steam to water heat exchangers. Both single and double-wall heat exchangers are available. Complete control packages can be factory-installed for hook up and run capability.

Limited Warranty Outline

Limited Warranty Outline

 N/A If the tank should leak any time during the first three years, under the terms of the warranty, State will repair or replace the heater; installation, labor, handling repair or replace the heater; installation, labor, handling and local delivery extra.

This outline is not a warranty. Warranty does not apply to product installed outside of the United States of America or its territorial possessions and Canada.

General Information

General Information

 N/A Solid State Modulating Step Control (All Models 180 KW and up)
  • Solid state electronic control device that modulates input to match load through progressive sequencing of steps (up to 20 steps with maximum of one per contactor).
Incoloy Immersion Heaters
  • Heavy-duty medium watt density elements (three/immersion heater) have incoloy sheathing: provide excellent protection against oxidation and scaling. The input ranges from 15 kW to 3000 kW
Glasslined Tank
  • Tank interior is coated with glass specially developed for use in water heaters. Tanks rated at 125 psi working pressure; 150 psi or 160 psi working pressure is optional. Vermin proof fiber glass insulation reduces costly heat loss. Constructed to Section IV of ASME code, and UL standards. Tanks have channel skid base. A 4" x 6" handhole is furnished on 500, 600 and 700-gallon models; 11" x 15" manhole is furnished on 800-gallon and larger sizes.
Fusing
  • Control and power circuit fusing to meet N.E.C.
Compliance
  • Meets the standby loss requirements of the U.S. Department of Energy and current edition of ASHRAE/IESNA 90.1.
Magnetic Contactor(s)
  • Heavy duty UL rated for 100,000 cycles.

 N/A Tank Linings

Cement - A special formulation of cement providing excellent corrosion protection. Available on 200-gallon and larger tanks.

Epoxy - A solvent less two component epoxy lining applied to a minimum ten-mil (0.010") dry thickness. Available on 200-gallon and larger tanks.

Special Construction

Special Construction

 N/A 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.

150 or 160 psi Working Pressure - Must be specified at time of order.

Other Optional Features

Other Optional Features

 N/A Temperature and Pressure Relife Valves - For working pressures other than standard; consult factory.

Horizontal and Vertical - Most gallon capacities may be obtained in vertical or horizontal construction.

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.

Optional International Voltages - 380 and 415 volts three phase.

3-1/2" Dial-Type Pressure Gauge - Factory-installed.

3-1/2" Dial-Type Temperature Gauge - Factory-installed.

11" x 15" Manhole - Available as option on tanks 700 gallons or smaller.

Control Options

Control Options

 N/A 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 SEV and SEH 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.

Terminal Blocks - Allows for remote connection to building demand limiter or other functions.

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).

Indicating Lights - Denotes heating stage(s) in operation. Up to one light per contactor is available.

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.

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.

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.

Circuit Breaker - A safety device which disconnects power to the heater in the event of overcurrent.
