SGV-4,5.2,5/4,5-I1-V-Ga

Purpose of the Vacuum Bell Furnace SGV-4.5.2,5/4,5-I1-V-Ga

The furnace is designed for thermal processing of materials in high vacuum (up to 5×10⁻⁵ mm Hg (≈ 6.7×10⁻³ Pa) at relatively low temperatures (up to 450 °C). It is a high-speed vacuum furnace for gentle (low-temperature) and clean heat treatment, where heating rate and the absence of oxidation are critical.

Main applications:

• Vacuum welding and brazing (e.g., fluxless brazing).
• Annealing and heat treatment of metals and alloys sensitive to oxidation (stainless steel, titanium, copper, ceramics).
• Drying and degassing of parts and materials prior to high-vacuum processes.
• Laboratory and experimental work — thanks to precise control (stability ±3°C or ±0.0015t) and the ability for very slow heating (from 0.1 °C/min).
• Processes requiring a clean environment — minimizing oil vapor ingress into the working chamber (with correct vacuum system operation).

The bell-type design is convenient for placing bulky or awkward parts — the chamber (diameter 450 mm, height 250 mm) is covered from above by a bell.

What Makes It Different

Unlike conventional furnaces with metal or graphite heaters, this model uses halogen lamps.

First — the heating rate reaches 300 °C/min, whereas standard furnaces accelerate tens of times slower.

Second — no significant contamination of the chamber by heater decomposition products. In furnaces with graphite or molybdenum, particles and evaporation products from heater materials may be released.

Halogen lamps operate cleanly, which is critical for electronics, optics, and precision alloys.

The bell-type design with bottom loading simplifies the placement of large or awkward items.

Application Recommendations

Furnaces of this type are best suited for shock heating of small-mass workpieces: thanks to halogen lamps, the heating rate reaches 300 °C/min, but the thermal inertia of the chamber limits effectiveness with massive parts.

It is recommended to consider models from the vacuum bell furnace line designed for working with massive parts.
