Product Overview

What Is an Atmosphere Furnace?

An atmosphere furnace is a specialized thermal processing system that heats materials inside a precisely controlled gaseous environment — preventing oxidation, enabling reduction reactions, or creating inert conditions that standard open-air furnaces cannot achieve.

Brother Furnace's atmosphere furnaces are built with hermetically sealed chambers, integrated gas flow management, and intelligent PID temperature control, making them the preferred choice for universities, R&D institutes, and advanced materials manufacturers worldwide.

Supported Atmospheres

Choose the Right Gas Atmosphere

Our atmosphere furnaces are engineered to work with the most common protective and reactive gases used in advanced materials processing. Each gas type opens up distinct process possibilities.

Nitrogen Atmosphere

N₂

Nitrogen is the most cost-effective inert gas for preventing oxidation and decarburization. Ideal for processes where a chemically neutral environment is required without the expense of argon.

Bright Annealing Powder Sintering Stress Relief Brazing

Argon Atmosphere

As a noble gas, argon provides the most chemically inert environment available. Essential for processing reactive metals such as titanium, zirconium, and rare-earth alloys at high temperatures.

Reactive Metal Processing Crystal Growth Rare-Earth Alloys High-Purity Sintering

Hydrogen Atmosphere

H₂

Hydrogen is a powerful reducing agent that removes surface oxides from metal parts, enabling bright, clean surfaces after heat treatment. Our hydrogen furnaces include integrated safety systems as standard.

Oxide Reduction Metal Powder Reduction Bright Hardening Catalyst Preparation

Forming Gas

N₂/H₂ Mix

A blend of nitrogen and hydrogen (typically 95%/5%), forming gas balances cost and reducing power. It is widely used for annealing stainless steel and electronic component processing.

Stainless Steel Annealing PCB Processing Semiconductor Packaging Soft Magnetic Alloys

Vacuum + Gas Backfill

Vac + Gas

Many models support an initial vacuum purge followed by inert gas backfill, achieving ultra-high atmosphere purity (<10 ppm O₂). This two-step process is critical for sensitive materials research.

CO / CO₂ & Custom Gas

Custom

For carburizing, atmosphere control research, or specialized thermochemical processes, our furnaces can be configured for CO, CO₂, methane, or any custom gas blend with appropriate safety provisions.

Key Features

Engineering Excellence in Every Detail

Every Brother Furnace atmosphere furnace is designed with the researcher in mind — combining robust construction, intelligent control, and comprehensive safety into one reliable platform.

30-Segment PID Control

Programmable 30-step temperature profiles with ramp, soak, and cool-down control. Accuracy within ±1°C for repeatable, publication-quality results.

Hermetically Sealed Chamber

High-grade stainless steel or alumina tube chambers with vacuum-rated flanges and silicone O-ring seals, ensuring gas integrity throughout the entire process cycle.

Multi-Layer Safety System

Hydrogen leak detection, automatic gas shutoff, over-temperature protection, and pressure relief valve — all standard on every unit. CE certified for global compliance.

Precise Gas Flow Control

Calibrated rotameter or optional mass flow controller (MFC) ensures accurate, repeatable gas delivery rates. Dual-port design supports gas mixing directly at the inlet.

Premium Insulation Materials

High-purity ceramic fiber insulation minimizes heat loss and enables rapid heating rates up to 30°C/min while keeping the outer shell cool and safe to touch.

PC Connectivity & Data Logging

USB / RS-485 interface with free PC software for remote monitoring, real-time curve display, and automatic data export to CSV — essential for research documentation.

High-Performance Heating Elements

Choose from resistance wire (≤1200°C), silicon carbide SiC (≤1600°C), or molybdenum disilicide MoSi₂ (≤1800°C) elements — matched to your exact temperature requirement.

OEM & Custom Design Ready

Chamber dimensions, power supply voltage, gas port configuration, and control system can all be customized to match your specific laboratory workflow and space constraints.

FAQ

Frequently Asked Questions

Answers to the most common questions our customers ask before selecting and ordering a vacuum sintering furnace.

What gases can be used in Brother Furnace atmosphere furnaces?

Our standard models support nitrogen (N₂), argon (Ar), hydrogen (H₂), and forming gas (N₂/H₂ blends). Certain models can also be configured for CO, CO₂, methane, or custom gas mixtures. Please specify your gas requirements when requesting a quote so we can ensure the correct safety provisions are included.

Is it safe to use hydrogen in your furnaces?

Yes. All Brother Furnace hydrogen-compatible models include a hydrogen gas leak detector, automatic gas shutoff valve, pressure relief valve, and an exhaust burn-off port as standard safety features. Our furnaces are CE certified and designed in compliance with international hydrogen safety standards.

What is the difference between a box-type and a tube-type atmosphere furnace?

Box-type atmosphere furnaces have a larger, rectangular chamber suitable for processing multiple samples or larger workpieces simultaneously. Tube-type furnaces use a sealed cylindrical tube (alumina or quartz) which achieves higher gas purity and is better suited for small samples, powder materials, and processes requiring vacuum + gas backfill. Tube furnaces also typically reach higher maximum temperatures.

Can I connect the furnace to my PC for data logging?

Yes. All models include a USB or RS-485 interface and free PC software for real-time temperature curve display, remote profile programming, and automatic data export to CSV format. An optional Ethernet interface with SCADA compatibility is available on high-end models.

What voltage options are available?

Standard models are available in 220V single-phase and 380V three-phase, 50/60Hz configurations. We can customize the power supply to match your local grid specification — including 110V, 208V, 240V, or 415V — at no extra charge when specified at the time of order.

How long does delivery take and what shipping methods do you offer?

Standard models ship within 7–15 business days after order confirmation. Custom configurations typically require 20–30 business days. We ship worldwide via sea freight, air freight, or express courier. Shipping terms available include EXW, FOB, CIF, and DDP (Delivered Duty Paid) depending on your destination.

Do you offer OEM or private-label furnaces?

Yes. Brother Furnace provides full OEM services including custom branding, modified specifications, and private-label packaging. We work with distributors, resellers, and equipment integrators globally. Please contact our sales team to discuss OEM pricing and minimum order quantities.

What warranty and after-sales support do you provide?
