Features INCOLOY-SHEATH HEATING ELEMENTS STANDARD Industrial-grade Incoloy sheathed heating elements are designed for rugged longlasting commercial service and can withstand sheath temperatures up to 816°C 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 95 to 838 litres per hour (Iph) at 56°C rise Deionized models equipped with stainless steel standard elements A. 0. 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 220 and 240 Volts are field convertible to three phase. CMC models, only 220,240 Volts at 24 KW and below are supplied as phase convertible units (single to three phase and vice versa).

IMMERSION THERMOSTAT FOR EFFICIENT CONTROL

Close-differential, immersion-type thermostat for superbly accurate temperature control Adjustable from 60°C to 85°C Manual reset, high-temperature cutoff.

HEAVY-DUTY MAGNETIC CONTACTORS

UL-rated 100,000 cycles

FACTORY-WIRED, 120V CIRCUIT CONTROLS

120V control circuit powered by fused transformer Eliminates need for 120V service connection

POWER-CIRCUIT FUSING FOR SYSTEM PROTECTION

Safeguards elements and contactors from short circuits, overloading and line surges when current draw exceeds 120A.

ALL STAINLESS STEEL JACKET

Cleans easily, corrosion resistant, hinged for easy serviceability Standard on CMC models, optional on SU models.

GLASS-LINED TANK, ASME TANK CONSTRUCTION

Specifically developed for high-temperature water heater use Provides long-lasting protection against corrosion Equipped with anode rod for additional corrosion protection Stainless steel tank on deionized models

MAXIMUM HYDROSTATIC WORKING PRESSURE: 10.34 Bar
CSA CERTIFIED AND ASME RATED T&P RELIEF VALVE
