Core Value

The 220V 380V Commercial Dishwasher Heating Element is an industrial-grade electric immersion heating element engineered for continuous duty in food service sanitation equipment, conveyor dishwashers, hood-type machines, and pot washers. Designed to meet strict commercial hygiene standards (NSF/HACCP), these heating elements deliver rapid thermal recovery to maintain wash tank temperatures at 60°C to 65°C and rinse booster temperatures at 82°C to 90°C for instant sanitization.

Featuring heavy-duty 316L Stainless Steel or Incoloy 800/840 sheath alloys, these elements resist harsh chemical detergents, high-alkaline sanitizers, and hard-water lime scaling. The element geometry—available in triangular flange, 1.5″/2″ BSP screw plug, or custom 3-bolt brass mounts—is configured for flexible 220V single-phase or 380V 3-phase (Star/Delta) wiring setups. Integrated thermowell pockets allow direct insertion of temperature limiters and thermostats. BACKED BY EXTENSIVE HEATER MANUFACTURING EXPERIENCE and engineered for maximum energy efficiency, every unit UNDERGOES MULTIPLE RIGOROUS QUALITY CHECKS to ensure zero electrical leakage, superior watt density distribution, and extended service life.

• ✓ Dual Voltage Flexibility: Easily wired for 220V single-phase or 380V three-phase Star/Delta power configurations to match regional commercial grids.
• ✓ Anti-Scale Sheath Alloys: Premium Incoloy 800 and 316L Stainless Steel options prevent chemical pitting and lime scale buildup in hard water.
• ✓ Rapid Thermal Recovery: High-watt-density heating loops bring rinse water up to $85^\circ\text{C}$ rapidly between dishwashing cycles.
• ✓ Built-In Thermowell Pockets: Features integrated capillary bulb pockets for precise thermostat and thermal cutoff fuse sensor alignment.
• ✓ Watertight Terminal Seals: High-temperature silicone or epoxy potted terminal heads protect electrical connections from steam and splash.
• ✓ Universal Mounting Options: Available with standard 1.5″ & 2″ screw plugs, triangular flanges, or custom OEM mounting plates.
• ✓ Reliable Quality: Engineered for high thermal efficiency and continuous 24/7 commercial kitchen operation.
• ✓ Quality Assured: UNDERGOES MULTIPLE RIGOROUS QUALITY CHECKS including high-voltage dielectric withstand testing (1500V/1min), insulation resistance testing, and hydrostatic pressure checks.

Technical Specifications & Performance Data

HT-Heater Dishwasher Elements vs Standard Market Options

Installation & Handling Guidelines

• Gasket & Seal Inspection: Always replace the flange gasket (O-ring, EPDM, or High-Temp Silicone) whenever installing a new heater. Ensure the mounting flange surface on the dishwasher tank is clean and free of scale.

• Dry-Firing Warning: NEVER energize the heating element until the dishwasher tank or booster cylinder is completely filled with water. Operating the element in air (dry-firing) will burn out the heating wire within seconds.

• Electrical Phase Wiring: Verify your supply voltage (220V 1-Phase vs. 380V 3-Phase). When wiring for 380V 3-phase, ensure the terminal jumpers are correctly positioned for Star or Delta connection according to the wiring diagram on the terminal cover.

• Scale Maintenance: In hard water regions, regularly descale the heating element loops using food-grade descaling solution. Accumulated lime scale acts as a thermal insulator, causing the element to overheat internally and fail.

• Thermostat Bulb Placement: When inserting the thermostat capillary probe into the integrated thermowell pocket, ensure it slides all the way to the bottom for accurate temperature feedback and reliable high-limit safety cutoffs.

Customer Success Stories

Case 1:

Plastic Film Extrusion Machinery OEM (Turkey)

• Application: Barrel temperature zone monitoring on multi-layer blown film extrusion lines.

• Challenge: Straight bayonet sensors were sticking out too far from the barrel insulation jackets, causing operators to bump into wires and break sensor connections.

• Solution: Type J Right Angle Bayonet Thermocouples with 90° SS elbows and heavy-duty SS braided lead cables.

• Results: ZERO ACCIDENTAL WIRE DAMAGE. “The 90-degree low profile keeps wires snug against the barrel insulation. Operators no longer snag cables, and temperature readings are perfectly stable.”

Case 2:

Commercial Warewashing Equipment OEM (Spain)

• Application: Factory assembly of high-speed rack conveyor dishwashers for commercial cafeterias.

• Challenge: Inconsistent terminal sealing on previous heaters allowed steam to enter element ends, tripping customer GFCI/RCD breakers during initial testing.

• Solution: Dual Voltage 220V/380V 12kW 316L SS Immersion Heaters featuring vulcanized silicone terminal seals and M5 brass posts.

• Results: 100% RELIABLE FACTORY TESTING. “The dual 220V/380V wiring capability makes exporting to different power grid markets easy. The watertight terminal potting completely solved our GFCI tripping issues.”
