Long Wave Infrared Heating Emitters (Kanthal)
Long wave infrared heating emitters operate in the far-infrared spectrum, delivering gentle, uniform radiant heat. They warm materials directly and also heat the surrounding air, creating a comfortable and stable temperature distribution. Because long infrared wavelengths are readily absorbed by organic substances, including human tissue, they are particularly suitable for applications that require mild and pleasant heat exposure.
Their low surface temperature and soft heating pattern make LWIR emitters a great choice for environments where comfort, safety, or sensitive materials are a priority.

Uniform heat dispersion across larger areas.Safe operating conditions
Lower heater surface temperatures reduce burn risks.Versatile integration
Available in single or twin tube configurations.Reliable performance
Kanthal resistance wire ensures long lifetime durability.
IR Long Wave Kanthal from DR. FISCHER Europe
Key Facts of IR Long Wave Kanthal:
Kanthal-based long wave emitters from DR. FISCHER operate with coil temperatures under 1200 K. Twin tube solutions are available in 33 × 15 mm geometry, while single tube diameters range from 14 mm to 16 mm. Heating lengths extend up to 2500 mm (twin) and 1500 mm (single). A power density around 25 W/cm supports mild, consistent heat output and energy-efficient operation in comfort-oriented and low-temperature industrial applications.
Specifications of IR Long Wave Kanthal
These emitters are designed for scenarios where intense radiant power is not required but a controlled and comfortable heat environment is essential. With their robust Kanthal heating wire and durable quartz glass construction, they provide long-lasting service in both commercial and industrial installations.

| IR reflectors | ||||||
|---|---|---|---|---|---|---|
| Reflectivity | Durability | Cost | Radiation orientation | Main advantages | Main drawbacks | |
| Gold | ☆☆☆☆☆ | Bad | €€€€€ | Specular | - Best reflectivity - No thermal inertia |
- Low temperature resistance (<600°C) - High cost |
| White ceramic | ☆☆☆ | Very good | €€ | Diffuse | - Good price-performance ratio | - Reflectivity 10 to 15% lower than gold |
| MLRI | ☆☆☆☆ | Very good | €€€ | Diffuse | - Reflectivity between the white ceramic and gold | - Slightly more expensive and slightly less stable than white ceramic |
| LRP | ☆☆☆☆ | Excellent | €€€€ | Specular | - Reflectivity close to gold - Auto-cleaning - Longer lifespan than all other reflectors |
- Expensive to start with (but no need to replace it with the lamp) - Thermal inertia |
| Highly reflective aluminum | ☆☆☆ | Good | €€€ | Specular or diffuse (depends of the finish) | - Can be combined with other reflectors | - Added piece → takes more space |
