1400℃ Laboratory Muffle Furnace

Energy-saving rapid heating Muffle Furnace

The Muffle Furnace utilizes a high-quality ceramic fiber furnace lining, offering rapid heating and excellent heat retention, resulting in greater energy efficiency compared to traditional refractory brick structures. Equipped with a microcomputer PID temperature control system, the equipment ensures high temperature control accuracy and minimal temperature fluctuations, guaranteeing the reliability and repeatability of experimental results. It is widely used in scientific research and industrial testing fields such as materials heat treatment, ceramic sintering, and ashing analysis.

Advantages of a 1400℃

1.Multi-Temperature Coverage Experimental Requirements

The heating rate can reach up to 40°C per minute (non-linear control). Combined with an intelligent temperature control system, it ensures heating efficiency while preventing thermal shock damage to the furnace structure and samples. Compared to traditional Muffle Furnace, it significantly reduces heating time and improves experimental efficiency.

2.with Three-Sided Heating

The furnace body adopts an air-cooled double-layer carbon steel structure with scientifically designed air-cooled guide baffles inside. Cold air flows through the furnace shell, cooling the conductive plates of the heating elements before being discharged, keeping the furnace shell surface temperature below 45°C. This design protects operator safety and prevents high-temperature oxidation of the heating element conductive plates, extending the service life of the Muffle Furnace.

3.High-Quality Insulation Material, Energy-Saving and Durable

The furnace lining uses vacuum-formed alumina lightweight material, which has advantages such as high operating temperature, almacenamiento de bajo calor, resistance to rapid heating and cooling, and no cracking or slagging. Excellent heat insulation performance effectively retains heat within the furnace chamber, resulting in significantly lower energy consumption compared to traditional refractory brick muffle furnaces.

4.Muffle Furnace Body with Double-Layer Air-Cooled Outer Shell for Low Temperature

The furnace door features a 180-degree axial side-opening design and is equipped with a flexible locking mechanism. This design effectively locks the door to ensure a tight seal and absorbs stress caused by the thermal expansion of the refractory material, preventing damage to the furnace structure and ensuring long-term reliability.

5.Multiple safety protections for reliable operation

The Muffle Furnace body is equipped with a door-opening power-off function, which automatically disconnects the main heating circuit when the furnace door is opened at high temperatures, reducing operational risks. It adopts an integrated modular control unit with dual-circuit control and dual-circuit protection functions, covering all-round protection such as overshoot, over-adjustment, under-adjustment, thermocouple breakage, pérdida de fase, over-pressure, over-current, over-temperature, comentarios actuales, and soft start.

Common problems with 1400℃ Muffle Furnace

1.Will the furnace lining material crack? What should I do if it cracks?

After a period of use, minor cracks may appear in the furnace lining of a Muffle Furnace. This is normal and will not affect its use. It can be repaired with an alumina coating.

2.What is the maximum heating rate?

A: To avoid affecting the furnace’s lifespan, a maximum heating and cooling rate of 1-15℃/min is recommended. (Rapid heating at high temperatures will shorten the lifespan of the heating elements.)

3.What are the program control functions? Can multiple process curves be stored?

The Muffle Furnace is equipped with a 50-segment program control function, supporting multiple curve configurations.

4.Can the furnace shell temperature really be controlled below 45℃?

Sí. TheMuffle Furnace uses an air-cooled double-layer carbon steel furnace body with internal air-cooled guide baffles. Cold air circulates and is discharged from the conductive plates of the heating elements, effectively removing heat.

5.Can the furnace be protected by an atmosphere?

The Muffle Furnace does not use a vacuum seal structure, so flammable and explosive gases should not be introduced. The introduction of corrosive gases is also not recommended. If you require the introduction of highly corrosive gases such as sulfur (S) or sodium (Na), please inform us in advance so that we can perform spec
