Muffle Furnace
Muffle Furnace 1100 0C to 1400 0C
Sanvi Heat SHMF series Muffle furnaces feature advanced polycrystalline mullite fiber insulation with a thickness of 120–250 mm, delivering outstanding thermal performance and low heat loss.
A double-layer shell with fan cooling maintains the surface temperature below 60 °C, ensuring operator safety. The reinforced furnace roof structure guarantees durability and stability under long-term continuous operation.
These furnaces are purpose-built for sintering, melting, and material analysis, suitable for metals, non-metals, and compound materials, and are extensively used in provide a clean, uniform, and controlled heating environment for laboratories, universities, research institutes, and industrial & mining enterprises.
Optional Parts
- Gas vent
- Observation hole
- Alumina crucible
- Software
Key Features
- Contamination-Free Environment: The muffle chamber isolates workpieces from heating elements and gases, making it ideal for analysis and material research
- Precise Temperature Control: units include digital/PID controllers with programmable thermal profiles for accurate ramping, soaking, and cooling cycles.
- 50 segments programmable and PID auto control
- High-Temperature Capability: Typical operating ranges span from ambient to 1100–1800 °C depending on the model and insulation materials used
- Uniform Heat Distribution: Engineered insulation and element layout ensure consistent thermal exposure throughout the chamber.
- With Over heat alarm function
- Cooling fan can reduce the temperature of the casting less than 60 0 C
- Safety & Efficiency: Double shell construction and effective insulating materials reduce energy loss and keep exterior surfaces cool, improving operator safety while lowering power costs.
- High quality resistance wire SiC heater and MoSi2 heater
- The upper door and the side door can be customized to keep the operator away from the heat source.
Application
Muffle furnaces are widely used in both laboratory and industrial environments for processes such as:
- Ashing and gravimetric analysis in chemical, environmental, and materials labs
- Sintering, annealing, tempering, or heat-treating metals, ceramics, and composites
- Ceramics firing, glass melting, and enamel coating production
- furnace chamber with three-sides heating: from both side walls and bottom
- Heating elements on support tubes ensure free heat radiation and a long service life
- Low energy consumption due to multi-layer insulation
- Controller with touch operation
Why Choose a Quality Muffle Furnace?
A well-designed muffle furnace delivers repeatable results, long service life, and energy efficiency. It is an indispensable tool for laboratories, research institutes, industrial producers, and quality control facilities that require precise temperature environments without contamination.
