Electro Industries Industrial Electric Water Boilers Electro Industries Industrial Boiler is a very compact and an effective solution to retrofitting old, inefficient fossil fuel boilers, or for use in new installations. Safety is one major benefit of these boilers. Several state electrical jurisdictions are requiring the (optional) Bender Insulation Monitor device (ground fault) for increased operating safety, personal protection and reliability of the boiler. Secondly, there are individual circuit breakers for each heating element, further increasing the safety and reliability of our boilers. Each boiler also includes built-in digital supply return and outdoor temperature sensors, enabling you to internally set and maintain the correct system design temperature, simplifying the installation process. Features & Benefits Pressure vessel built in accordance with the requirements of the ASME Boiler and Pressure Vessel Code (National Board and CRN registered) Compact, can easily fit through service doors High efficiency electric boiler with no combustion waste No minimum return water temperature required Individual circuit breakers for each heating element All boilers come fully assembled; control box is within front door Built-in digital temperature sensing; adjustable desired temperature allows the user to set the boiler to operate at a specific supply temperature (set point mode) Outdoor reset (can be enabled or disabled) Outdoor reset sensing and software (reset mode) Operator alarm monitor and control functions including manual resets are in the control box All parts within the boiler are rated for 60 C Optional Honeywell T775R temperature control Made in USA 0-10VDC terminal enabling control of boiler via building automation system, etc. Software and interface cable for setup, monitoring, and troubleshooting Transformer Wiring Configurations Standard boiler - add to building electrical service, 4-wire but no neutral current. All service wiring design, safety and ground fault equipment, NEC special code application, etc. are the responsibility of the installer. Standard boiler with option ground fault monitor - suitable for use with a 3-wire Delta service, dedicated utility transformer (Delta or unbonded/neutral). All control and protection needed to meet NEC Article 250 is included.
Product Specifications The electric hot water boiler shall be an Electro Industries, Inc. model number EB-NB-. The Boiler output shall be Btu/h or kw at volts three phase. Wiring within the main cabinet shall be rated at 75 C or higher. Aluminum or copper conductors may be used for field installed power wiring. The boiler shall include provisions to connect directly to utility load control. The boiler shall include a dedicated 15A 120V single phase control circuit (general service). As a preferred option the boiler (dependant upon kw) shall be wired using (2) three phase delta feeds without neutral (unbonded neutral) within the dedicated utility transformer XO terminal. All Delta 3-phase require optional Bender fault monitor. The vessel shall be wrapped with 3 insulation. The vessel shall be enclosed in a 14 gauge fully enclosed cabinet. The cabinet and vessel shall be attached to a 10 gauge structural steel base. The base includes integral fork pockets for easy maneuvering during installation. Both base and cabinet shall be painted with powder coated enamel. The cabinet shall include a full length hinged door with an included lockable T-handle. The inside dead front panel shall include an integral door safety interlock switch. The vessel shall have a capacity of 40 gallons. The vessel shall be H stamped and National Board registered with a maximum working pressure of 30 or 125 PSI. The Vessel shall have 3 NPT threaded inlet and outlet nozzles. The outlet nozzle shall be located on the top of the vessel. The inlet nozzle shall be located on the left side of the vessel. The immersion heating elements shall be installed in the top of the vessel and threaded into vessel for easy servicing (water draw-down not required). The heating elements shall be constructed using incoloy sheathing for long service life. The low-watt density heating elements shall be 30 in length. The cabinet shall have a split cover top for easy access to the heating elements. Contactors used to operate the heating elements shall be rated for 500,000 cycles. The boiler shall include mounted control enclosure. The control enclosure shall contain all boiler controls and adjustments. Operator is not required to enter main cabinet for resets or other functions. A window shall be included on the door of the control enclosure to permit viewing of monitor and alarm LED s. The control assembly shall include a six function alarm LED. The sequencer shall include provisions for stage rotation. An optional emergency stop switch can be field installed at the terminals provided in the boiler.
