Commercial Electric Water Heaters
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.

INColoY-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
