Product Overview
The Tubular Coil Heater is a specialized industrial heating element designed to deliver high thermal output within a compact footprint. Constructed from a seamless metal tube bent into a tight helix, this heater is filled with high-purity magnesium oxide (MgO) to ensure superior heat transfer from the internal resistor wire to the outer sheath. It is the preferred solution for applications requiring rapid heating, excellent mechanical strength, and resistance to high pressure.
Key Features & Benefits
Superior Heat Transfer: The MgO-packed construction eliminates air gaps, ensuring efficient conduction of heat from the core to the coil surface, preventing hot spots and extending element life.
Increased Surface Area: The coiled configuration provides more heating surface per linear inch compared to straight tubular elements, resulting in faster heat-up times and better energy efficiency.
Mechanical Resilience: The helical shape acts as a natural expansion joint, allowing the element to absorb thermal stress and vibration without deforming or cracking.
Corrosion Protection: Available with a Stainless Steel 304/316 or Copper sheath, providing long-term protection against rust and chemical degradation in harsh environments.
Core Applications
Liquid Heating: Ideal for heating water, oils, and chemicals in tanks and vessels where immersion heating is required.
Air Duct Heating: Used in industrial dryers, ovens, and HVAC systems to heat moving air streams efficiently.
Pipeline Heating: Wrapped around pipes to maintain fluid viscosity and prevent freezing in process lines.
Mold Heating: Inserted into drilled holes in metal molds to provide uniform heat distribution for manufacturing processes.
Quality & Reliability
Precision Engineering: Manufactured using computer-controlled coiling machines to ensure consistent pitch and diameter, guaranteeing a perfect fit in your application.
Rigorous Testing: Each unit is subjected to high-voltage insulation testing and pressure testing to ensure leak-tight integrity and electrical safety.
