SPECIAL CONSTRUCTION
SILICON BRONZE VESSELS – Are available for special applications or very corrosive water conditions. Consult fac- tory for specific sizes.
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 speci- fied at time of order.
OTHER OPTIONAL FEATURES
TEMPERATURE AND PRESSURE RELIEF VALVES – For working pressures other than standard; consult factory.
HORIZONTAL OR VERTICAL – See specifications, 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.

CONTROL OPTIONS
COPPER TUBE TANK HEATER – Double wall copper tube tank heaters are designed for heating potable water with both potable or
THERMOSTATIC STEP CONTROL – The simplest form of modulation. Allows elements to be stepped on in groups by specifying additional thermostats (up to one per contactor). It is recommended that number of thermostats not exceed five.
SOLID STATE MODULATING STEP CONTROL – 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).
SEQUENCER – Up to 5 stage time delay sequencer pro- vides for stepping of elements in groups or individually (maxi- mum of one step per contactor). Units supplied with this option will have a 120/24 volt control circuit.
TERMINAL BLOCKS – Allows for remote connection to build- ing demand limiter or other functions.
AUTOMATIC RESET HIGH LIMIT – A control that in the event of high temperature, interrupts power,
INDICATING LIGHTS – Denotes heating stage(s) in opera- tion. 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 overcurrent, high temperature or low water level, breaker must be manually reset.
