Programmable Muffle Furnace

A Programmable Muffle Furnace is a laboratory and industrial device designed for high-temperature applications where precise temperature control and automatic thermal cycling are required. These furnaces feature advanced temperature controllers—often PID type—that can store and execute multi-segment heating programs, enabling users to set complex ramp/soak profiles and automate thermal treatment processes.

Key Features

• Programmable temperature profiles with 10–32 segments, allowing ramp, soak, and hold cycles for sophisticated thermal processing.
• PID digital controllers for accurate, stable temperature control, reducing overshoot and improving uniformity.
• Maximum operating temperatures typically range from 1200°C to 1700°C, depending on model and manufacturer.
• High-quality insulation (ceramic fiber or high alumina fiber board) and robust heating elements (Kanthal, silicon carbide rods) for efficient energy use and heat distribution.
• Safety features such as overheat protection, automatic power-failure recovery, and chamber door interlocks.

Applications

• Heat treatment of metals, alloys, and ceramics.
• Sintering of powders and catalysts.
• Ash content determination in analytical laboratories.
• General laboratory use for combustion, sample drying, and material testing.

Advantages

• Automation saves time and increases repeatability of experiments.
• Precise control ensures material consistency and quality.
• Programmable profiles support complex heating requirements for research and production.

A programmable muffle furnace is vital for processes needing high temperature stability and flexible programming, making it a preferred choice in scientific, academic, and industrial settings.

Accumax India High Temperature Muffle Furnace

Powder-coated mild steel sheets make up the outer casing. A temperature control unit consisting of a PID controller, two pilot lamps, an ampere meter, a voltage meter, and an electric supply that operates on 220/440 volts at 50/60 Hz AC prevents energy loss with low voltage, high current transformers. The heating elements are made of silicon carbide rods and are protected by high temperature ceramic wool insulation.
