Box-Type Muffle Furnace — Multi-Stage Programmable Control

Leveraging our company’s years of experience in design and manufacturing, this furnace is specially designed for laboratories in industrial and mining enterprises, universities, and scientific research institutes. It is ideal for chemical element analysis and high-temperature heat treatments of small steel parts, such as quenching, annealing, and tempering. It can also be used for high-temperature heating applications like the sintering, melting, and analysis of metals, stones, and ceramics.

Product Features:

Advanced Door Design: The furnace door design ensures safe and simple operation, guaranteeing that high-temperature heat from inside the furnace does not leak out.
Space-Saving Controller: The controller is installed below the furnace door to save space and can meet various rapid sintering requirements.
Microcomputer PID Controller: Easy to operate, providing precise, reliable, and safe temperature control.
Durable, Lightweight Chamber: The corrosion-resistant, lightweight furnace chamber ensures long-lasting durability.
Excellent Door Sealing: A superior door seal minimizes heat loss and enhances temperature uniformity within the chamber.

Multi-Stage Programmable Controller

This microcomputer-based controller allows you to program temperature, time, and heating rates, enabling a wide variety of sintering experiments to be performed at high speed.
The programmable controller can preset up to 7 groups with 63 steps in total (9 steps per group). The time for each step can be set from 0 to 5999 minutes.
It utilizes a microprocessor P.I.D. control method with multi-stage programming to achieve true automatic control and operation.

Safety Functions

Comprehensive Safety Monitoring: Includes an over-temperature protector, a door open/close switch controller, a cooling fan for the furnace body, and an alarm system for furnace malfunctions (e.g., ① heater failure, ② temperature sensor failure, ③ memory error, ④ over-temperature deviation). Both sound and light alarms alert the operator, ensuring the furnace operates safely without accidents.
Electrical Protection: Equipped with multiple safety measures including over-current, over-voltage, and overheating protection to ensure safe use.
Superior Insulation: Uses ceramic fiberboard as the insulation material, which provides excellent thermal insulation and keeps the external casing temperature low.
