dura-power
180°f booster models
Dura-Power® commercial electric water heaters are designed to boost the water temperatures for applications such as commercial dishwashers, which require very high temperature sanitizing rinse—typically 180°F. Both 5-gallon countermount “CMC” models and 20-gallon “SU” models are available with inputs up to 54 kW. Are models are also available with an optional stainless steel tank for use with deionized water.
FEATURESINCOLOY-SHEATH HEATING ELEMENTS STANDARD
Industrial-grade Incoloy sheathed heating elements are designed for rugged long- lasting commercial service and can withstand sheath temperatures up to 1500°F Each heating element has three separate heating loops, which provides more heating surface, lower watt density and maximum recovery efficiency
Pre-wired leads provide excellent protection against oxidation and scaling
Input options from 6 kW to 54 kW, recoveries from 25 to 221 gallons per hour (gph) at 100°F rise
Deionized models equipped with stainless steel standard elements
A. O. SMITH GOLDENROD ELEMENTS OPTIONAL
Patent-pending 24k gold-plated sheath plus medium watt-density ensures even longer element life
Higher resistance to scale build-up, compared to Incoloy elements Three-year warranty against failure due to lime scale build-up Not available on deionized models
STANDARD VOLTAGES FOR EASY INSTALLATION
Single-phase and three-phase
Single-phase 208V and 240V are field-convertible to three-phase
CMC models only, 208V and 240V at 24 kW and below are supplied as phase-convertible units (single- to three-phase and vice versa)
