Vessel Construction

1. All welded carbon steel vessel designed and built in strict accordance with the ASME Code Section IV and stamped, certified, and registered with the National Board of Boiler and Pressure Vessel Inspectors.
2. All internal tank surfaces are lined with a minimum of 5/8" thick Hydrastone cement for superior protection and tank longevity.
3. Designed for 100psi working pressure and hydrostatically tested at 150psi (1½ times the WP).
   

Vessel (options)

1. Alternate protective lining:
   phenolic epoxy resin.
2. Alternate vessel construction:
   Stainless Steel Type 304 or 316L, 90/10 Copper-Nickel, other.
3. Alternate working pressure:
   please specify

General

1. Heavy duty 2" thick fiberglass blanket insulation covers the pressure vessel for maximum operating efficiency and minimal standby heat loss.
2. Heavy gauge galvanized steel protective jacket holds insulation in place and protected to ensure highly efficient operation.
3. Integrally welded bulkhead attachment points.
4. Entire vessel is supported on heavy duty integrally welded steel supports for sturdy deck mounting.
5. Full five (5) year Non Pro-Rated tank warranty and one (1) year electrical component warranty.
6. Bronze ASME rated combination temperature and pressure safety relief valve set at the vessel working pressure and 210°F.
7. ABS approved and in conformance with USCG regulations.

General (options)

1. Skid mounting on heavy duty all wedled I beam.
2. Type 304 stainless steel protective jacket, please specify if painted.
3. Dual energy package provides operational flexibility for electric and (steam or boiler water) power.

Electrical Operationg Controls

1. All electrical operating controls are factory sized, selected, wired, tested, and mounted in a NEMA 1 enclosure to ensure safe and reliable operation.
2. A power distribution block is supplied for single point electrical installation.
3. Power fuses rated at maxmimum of 60 Amps protect each heating element branch circuit per NEC and UL requirements. Each branch circuit has a maximum rating of 48 Amps.
4. Heavy duty definite purpose magnetic contactor with integrally mounted power fuse block assembly switches power on/off to each branch circuit.
5. Heavy duty removable flange type copper sheathed immersion heating element provides long service life.
6. Fully adjustable thermostat maintains accurate water temperature and is sized by the factory to control the appropriate number of heating element circuits.
7. A generously sized transformer provides fused 120V to the control circuit.
8. A fully adjustable (100-240°F) safety hi-limit device with manual reset interrupts power to the control circuit in the event of over-temperature water in the storage tank.
9. Safety door interlock mechanism interrupts power to the control circuit upon opening the electrical control panel.
10. Louvers in the control panel allow for cooling of the electrical components to ensure maximum electrical component longevity (when required).

Electrical (options)

1. NEMA 4 watertight enclosure for outdoor/wet locations.
2. Explosion resistant enclusure for hazardous locations. Please specify class, division, and group.
3. Built-incircuit breaker (with or without shunt trip) or a built-in non-fused On/Off disconnect switch.
4. Alternate element sheath material (please specify: Incoloy, Stainless Steel, other).
5. Specialiazed heating element construction including: Special watt density rating, passivation, electropolishing, hermetic seals, or any other feature required to meet the needs of your application.
6. Factory installed low water cut out device to disengage electrically the heating element(s) in the event of insufficient water in the tank.
7. Dial thermometer and pressure gauge factory installed in the tank.
8. Intra-tank circulation pump package with On/Off switch to continuously circulate water within the tank and thereby reduce stratification. All bronze circulator pump is rator 1/12 HP, 120V, 1 Ph.
9. Status indicationg lamp(s).
10. Audible alarm system.
11. Digital display electronic temperature controller. Please specify with or without RS485 communication port for remote operation of the temperature controller.
