Core Value: The 300mm Stainless Steel Finned Strip Heater 500W-1000W is engineered for high-efficiency forced air and natural convection heating in demanding industrial environments. By continuously brazing stainless steel cooling fins onto a heavy-duty sheath, the total surface area is expanded by 500%, facilitating rapid heat dissipation into the air stream without overheating the internal resistance core. Capable of handling sheath temperatures up to 500°C (932°F), this compact 300mm unit delivers robust thermal transfer for duct heating, load banks, and moisture-prevention control cabinets. BACKED BY 30+ YEARS MANUFACTURING EXPERIENCE and UNDERGOES MULTIPLE RIGOROUS QUALITY CHECKS for continuous, long-term industrial operation.

• ✓Maximized Surface Area: Stainless steel cooling fins increase heat transfer to air by 5x compared to standard smooth strip heaters.

• ✓ Compact High Power: Achieves high watt density capabilities ($500\text{W} – 1000\text{W}$) within a modular 300mm footprint.

• ✓ Heavy-Duty Construction: Corrosion-resistant SS304 sheath withstands high humidity and harsh factory atmospheres.

• ✓ Rapid Thermal Recovery: Low thermal mass allows for fast ramp-up times and precise PID temperature response.

• ✓ Vibration Resistant: Mechanically bonded fin structure eliminates rattling and thermal fatigue under continuous cycling.

• ✓ Easy Installation: Integrated mounting tab slots accommodate standard hardware and allow for thermal expansion.

• ✓ Reliable Quality: 30+ YEARS MANUFACTURING EXPERIENCE guarantees long service life.

• ✓ Quality Assured: UNDERGOES MULTIPLE RIGOROUS QUALITY CHECKS including high-voltage insulation testing.

• ✓ Global Standards: CE, LVD, RoHS, and ISO 9001 certified.

Technical Specifications & Performance Data

Industrial Applications & Solutions

1. HVAC & Air Duct Heating: Booster heating elements in air ducts and forced-air drying chambers, delivering efficient heat transfer with minimal pressure drop.

2. Electrical Control Cabinet Dehumidification: Gentle, uniform convection heating to prevent moisture condensation and freezing in outdoor telecom and power distribution panels.

3. Resistive Load Banks: Rapid heat dissipation for generator and battery testing load banks, preventing element burnout under high current loads.

4. Industrial Drying & Curing Ovens: Convection air heating for paint drying, textile setting, and food dehydration equipment.

5. Shrink Packaging Tunnels: Hot air circulation elements for shrink wrap packaging tunnels, ensuring quick thermal recovery for fluctuating conveyor speeds.

6. Dehumidification & Regeneration: Used in industrial desiccant air dehumidifiers to heat regeneration air streams.

HT-Heater vs Standard Market Heaters

Installation & Integration Guidelines

• Airflow Orientation: Install heaters so the cooling fins run parallel to the direction of airflow to minimize air resistance and maximize heat stripping.

• Bank Spacing: Maintain a minimum distance of 50mm between adjacent finned strip heaters when mounting them in banks to prevent radiant heat overlap.

• Thermal Expansion Allowance: Utilize the slotted mounting holes at the ends. Do not fix both ends rigidly without expansion clearance, as thermal expansion during operation can cause bowing.

• Wiring Protection: Use high-temperature nickel-plated steel ring lugs with silicone-fiberglass sleeving. Torque terminal nuts carefully to avoid shearing the stud posts.

• Airflow Interlock: Install an airflow interlock switch in forced-air systems to automatically shut off power to the heaters if the blower fan fails.
