SECTION I - GENERAL DESCRIPTION AND CONSTRUCTION

GENERAL DESCRIPTION

This book describes a packaged electric heater that is a stationary, self-contained unit. The complete assembly consists of the pressure vessel, immersion electric heating element, thermostat, safety relief valve, safety high temperature cut out, magnetic contactor(s), power circuit fusing, fused low voltage control circuit transformer, and any other required electrical operating control. Optional equipment may be supplied with your unit. Please consult the product drawing for details specific to your assembly. The unit is factory assembled, insulated, jacketed, wired, tested, and ready for electrical and plumbing service connections.

CONSTRUCTION

PRESSURE VESSEL

Standard Vessel Construction:

The standard pressure vessel is constructed of all welded carbon steel, then hot dip galvanized for added corrosion resistance. Units over 58 kW are designed and built in accordance with ASME Section IV and stamped, certified, and registered with the National Board of Boiler and Pressure Vessel Inspectors. The maximum allowable working pressure is stamped on the nameplate. The standard working pressure is 150 psi (225 psi TP).

Optional Non-Ferrous Vessel Materials:

1.Copper-Silicon – A copper-silicon alloy offers tremendous longevity due to its ability to withstand the cycling effects induced from changes in water temperature and pressure. This material is suitable for storage of hot potable water in a variety of commercial and industrial applications.

2.90/10 Copper-Nickel – A 90% copper and 10% nickel alloy similar to copper-silicon, but with added strength and corrosion resistance. Typically used in applications with corrosive environments (salt water) or critical applications.

3.Stainless Steel – Stainless steel (type 304, 316, or 316L) is well suited for high purity applications requiring a corrosion resistant tank with minimal leaching of impurities into the water. Well suited for process, RO, and DI water systems in the pharmaceutical, food, and electronic industries.

4.Other materials are available upon request.

Optional Working Pressures:

The pressure vessel may be supplied with optional working pressures (standard working pressure is 150 psi). See drawing for details.

VESSEL CONNECTIONS

The heater is supplied with separate cold water and hot water connections. A connection is provided for mounting a combination safety temperature and pressure relief valve. An overflow line should be utilized from the relief valve outlet to a floor drain. See drawing for locations and sizes.
