INDUSTRIAL FURNACES
Kanthal heating technology for industrial furnaces — from batch and continuous heat treatment to high-temperature ceramic and glass firing. Temperatures up to 2,000°C, controlled and repeatable.
ELECTRIC RESISTANCE HEATING FOR INDUSTRY
Industrial electric furnaces using Kanthal resistance heating elements provide clean, controllable, atmosphere-compatible heat for a wide range of metallurgical, ceramic, glass and process applications. Unlike gas-fired alternatives, electric element furnaces deliver uniform temperature distribution, precise temperature control (±2°C at setpoint), no combustion products and lower maintenance requirements.
U3S Engitech supplies Kanthal heating elements, ceramic fibre insulation modules and complete electric furnace heating assemblies for retrofits and new installations across Eastern India's industrial base.
KANTHAL FURNACE HEATING — ADVANTAGES
- Operating temperatures from ambient to 2,000°C with single element range
- Precise setpoint control — ±2°C achievable in stable conditions
- Clean, combustion-free heating — suitable for controlled atmospheres
- Lower maintenance vs. gas — no burners, pilots, combustion air systems
- Long element life when correctly specified — some installations > 15 years
- Energy-efficient at part load — electric resistance loads proportionally
KANTHAL ELEMENT TECHNOLOGY
FeCrAl METALLIC ELEMENTS
Kanthal A-1, Kanthal AF, Kanthal D alloys — iron-chromium-aluminium resistance wire and ribbon for furnace temperatures up to 1,400°C. The original and most widely used industrial heating element.
Available in wire, strip, coiled, corrugated and swaged rod forms. Rated for air and mildly oxidising atmospheres.
SILICON CARBIDE (SiC) ELEMENTS
Kanthal Globar SiC elements — robust, high watt-density heating for furnace temperatures from 1,200°C to 1,600°C. Straight, spiral, multi-shank and double-end connection variants.
Preferred for steel billet heating, aluminium heat treatment and refractory sintering. Resists thermal shock.
MoSi₂ ELEMENTS
Kanthal Super (molybdenum disilicide) elements for the highest temperatures — 1,400°C to 1,850°C in oxidising atmospheres. Bent, straight and special-shape elements for lab and production kilns.
The technology of choice for technical ceramics, advanced materials, specialty glass and electronic components.
CERAMIC FIBRE INSULATION
Vacuum-formed and Z-Block ceramic fibre modules for furnace lining — matched to the element specification. Reduces heat storage mass, accelerates heat-up, reduces energy consumption vs. castable refractories.
TEMPERATURE CONTROL SYSTEMS
Thyristor (SCR) power controllers, PID temperature controllers, thermocouples and thermocouple heads. Complete control panel supply for element retrofits and new furnace installations.
COMPLETE FURNACE PACKAGES
Modular electric furnace systems for batch and continuous heat treatment — tempering, annealing, hardening, stress relief, brazing. Specification and supply for Eastern India's engineering sector.
