Description

Key Features & Benefits

Unrivaled Thermal Conductivity: At the heart of this heater is a Copper Sheath. Copper conducts heat approximately 20 times faster than stainless steel. This eliminates internal "hot spots" on the element surface, ensuring even heat distribution and preventing the overheating or scorching of sensitive liquids.
Corrosion Resistance & Longevity: Copper naturally resists oxidation and forms a protective patina. This makes the heater exceptionally durable in soft water, humid environments, and closed-loop systems where traditional steel elements might corrode or pit.
Robust Construction & Sealing: The heater features a heavy-duty copper tube and a sealed terminal block or brass fitting. This design prevents moisture ingress and ensures electrical safety, even when submerged in pressurized tanks.
Ease of Maintenance: Featuring standard threaded connections (such as BSP or NPT), the immersion heater can be easily screwed into a tank's inlet. This allows for quick inspection, cleaning, or replacement without draining the entire system.

Advanced Quality Assurance & Testing Protocol

To guarantee absolute safety and performance, every Copper Electric Immersion Heater undergoes rigorous validation:
Potable Water Certification: The wetted materials (copper, brass) are tested and certified to meet global drinking water standards (e.g., NSF/ANSI 61, WRAS), ensuring safety for domestic and food applications.
High-Potential (Hi-Pot) Test: A critical safety test where 2000V AC + 2x rated voltage is applied for 1 minute. This verifies the dielectric strength of the internal insulation.
Insulation Resistance Test: Conducted at 500V DC, the resistance must exceed 500 MΩ at room temperature. This ensures the Magnesium Oxide (MgO) core is completely dry.
Pressure & Leak Testing: The entire assembly is pressurized to 2x the maximum operating pressure and submerged to detect any micro-leaks, ensuring 100% integrity of the copper sheath and seals.
Operational Burn-In: Every unit is powered at 110% of rated load to verify thermal stability before shipment.
