Retort Atmosphere Furnace

CVSIC Retort Atmosphere Furnace is a high-efficiency thermal processing system designed for precise sintering, annealing, and heat treatment in controlled atmospheric conditions. Utilizing a hot-wall external heating design, it separates the heating elements from the furnace chamber, significantly extending component lifespan and reducing the risk of contamination.

It supports inert (N₂, CO₂, Ar) and oxidizing atmospheres (air, oxygen) with a vacuum level up to 7×10⁻³ Pa, making it suitable for a broad range of high-purity material processes, including ceramics, powder metallurgy, electronic materials, and rare earth research. The system combines PID temperature control, modular atmosphere control, and multi-layer safety protection, making it a dependable choice for laboratories, R&D centers, and production environments.

CVSIC Retort Atmosphere Furnace Features

External Hot-Wall Heating: Heating elements are placed outside the furnace chamber, avoiding direct material contact and improving component life and thermal stability.

 High Temperature & Precision Control: Maximum temperature of 1000°C; operating temperature up to 950°C. The PID controller ensures ±1°C accuracy (±2°C during gas charging), with ±5°C uniformity across the working zone. 

Versatile Atmosphere Support: Compatible with N₂, Ar, CO₂, oxygen, and air; customizable gas inlets and flow control (float/proton flowmeters). Cold-state vacuum up to 7×10⁻³ Pa.

Robust Furnace Chamber: Heat-resistant steel structure with corrosion-resistant insulation, providing stability under repeated thermal cycling.

Advanced Safety System: Features include over-temperature alarms, gas protection interlocks, an explosion-proof design, and multi-mode gas emissions, ensuring safe operation and compliance with environmental regulations. 

Energy Efficient: Optimized thermal insulation and structure reduce heat loss, improving energy efficiency during extended cycles. 

User-Friendly Control: Manual and automatic operation modes are supported, with heating rates of up to 10°C/min, allowing for flexible process tuning.
