JXL-620 Energy-Saving Rapid Intelligent Muffle Furnace
Product Overview
The JXL-620 Energy-Saving Rapid Intelligent Muffle Furnace is a high-performance laboratory ash furnace (commonly known as an ash furnace / muffle furnace) designed for fast ashing, volatile matter determination, and high-temperature heat treatment. It is widely used in coal, petroleum, power generation, chemical engineering, metallurgy, cement, geology, pharmaceuticals, and research laboratories.
Equipped with a microprocessor-based intelligent control system, the JXL-620 muffle furnace delivers rapid heating, precise temperature control, and energy-efficient operation. It supports multi-stage programmable heating curves, making it an ideal solution for modern industrial analysis and laboratory testing.

Key Performance Features
• Three-sided heating (left, right, and top) ensures uniform temperature distribution
• High-quality imported integrated fiber furnace chamber for superior insulation
• Fast heating speed with significant energy savings (up to 2/3 electricity reduction)
• Microprocessor intelligent control system with automatic temperature adjustment
• Chinese LCD display with touch keypad for intuitive operation
• Supports 15-segment programmable temperature-time control
• Built-in standard programs: fast ash, slow ash, volatile matter, Roga index, caking index
• Dual-layer housing structure with cold-rolled steel + stainless steel spray coating
• Long service life with robust structural design and stable performance
• Easy operation with reduced human error and improved efficiency

Working Principle
The JXL-620 muffle furnace operates through resistance heating using nickel-chromium alloy heating elements embedded around the furnace chamber. The microprocessor controller precisely regulates power output based on programmed temperature curves.
A K-type thermocouple (NiCr–NiSi) continuously monitors the internal temperature. The system automatically adjusts heating intensity to maintain stable temperature control and ensure compliance with national standards such as GB212, GB5447, and GB5449.
Heat is evenly distributed through a three-sided heating structure, ensuring consistent sample processing during ashing and thermal analysis.
