Finned Heaters for Efficient Air & Duct Heating
Configurable finned tubular & finned strip heaters engineered for ovens, ducts, and forced-air systems—optimized watt density, rugged materials, and short lead times.
Our Finned Heater Product Line
Families
- Finned Tubular — straight or formed; single- or double-ended
- Finned Strip — 0.375″ thickness class; bolt-on
- Finned Cartridge* — select localized air heat
*Verify airflow; cartridge sheath temp rises faster.
Applications
- Make-up air & process ovens, drying tunnels
- Cabinet/enclosure heating; dehumidification
- HVAC reheat and test chambers
Performance
Why Choose Elekheat

Thermal Headroom
Optimized fin pitch and furnace-brazed or mechanically bonded fins for efficient heat transfer and lower sheath temperature.

Materials for duty
Steel for clean, dry air; 304/316L for humidity/corrosion; high‑nickel Incoloy® for elevated temperature oxidation resistance.

Forming & Mounting
Precision bending (min. radii by diameter) with bulkhead fittings, collars, locator washers, and brackets.

Electrical Integrity
High dielectric strength, megger tested, moisture‑sealed terminals; optional hermetic feed-throughs.

System Integration
Banked arrays, terminal boxes, and safety interlocks (airflow, high‑limit thermostats, SSR/thyristor control).

Documentation
2D/3D CAD, watt density guidelines, airflow sizing worksheet, and agency files.
Finned Heater Manufacturing Process

Element build
Nickel‑chromium resistance coil centered in a metal sheath; compacted with high‑purity MgO for thermal conduction and dielectric strength.

Finned
Helical metal fins wound onto the sheath; bonding via furnace brazing for steel fins (or mechanical wrap for SS/Monel); selected fin pitch (typically 4.5–6 fins/in).

Forming
Anneal and bend to geometry; maintain minimum bending radii by diameter to protect MgO pack.

Terminations & seals
Studs, quick-connects, lead terminations with ceramic/mica insulators; moisture seals (RTV, epoxy, glass-ceramic); optional hermetic terminals.

Surface treatment
High‑heat aluminum coating, high‑emissivity black, nickel plate, or bright‑annealed finish; optional passivation for stainless.

Quality assurance
Resistance & tolerance check, hipot and insulation resistance, visual fin bond inspection, sheath straightness/runout, marking & serialization.
