nVessel Construction

1. 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 (units over 58 KW only).
2. All welded carbon steel construction hot dip galvanized after fabrication for added corrosion resistance.
3. Designed for 150psi working pressure and hydrostatically tested at 225psi (11/2 times the WP).

nGeneral

1. Heavy duty 2" thick fiberglass blanket insulation covers 100% of the pressure vessel for maximum operating efficiency and minimal standby heat loss.
2. Heavy gauge galvanized steel protective jacket with both top and bottom heads keeps insulation in place and protected to ensure high efficiency during operation.
3. Horizontal configuration supported on heavy duty integrally welded steel I beam supports for sturdy floor mounting.
4. Full five (5) year Non Pro-Rated tank warranty and one (1) year electrical component warranty.
5. Bronze ASME rated combination temperature and pressure safety relief valve set at the vessel working pressure and 210^oF.

nElectrical Operating Controls

1. All electrical operating controls are factory sized, selected, wired, tested, and mounted in a NEMA I enclosure to ensure safe and reliable operation.
2. A power distribution block is supplied for single point electrical installation.
3. Fast acting power fuses rated at a maximum 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 resistive load type magnetic contactors with integrally mounted power fuse block assembly.
5. Heavy duty removable flange type copper sheathed immersion heating element provides long service life.
6. Factory installed flow switch prevents element ignition in low/no flow conditions.
7. Factory installed low water cut out device prevents element ignition if there is no water in the unit.
8. Fully adjustable temperature controller maintains accurate water temperature and is sized by the factory to control the appropriate number of heating element circuits.
9. A high quality generously sized transformer provides fused 120V to the control circuit
10. A fully adjustable (100-240^oF) safety hi-limit device with manual reset interrupts power to the control circuit upon opening the electrical control panel.
11. Safety door interlock mechanism interrupts power to the control circuit upon opening the electrical control panel.
12. Louvers in the control panel allow for cooling of the electrical components to ensure maximum electrical component longevity.
