Product Overview
Labotemp Vacuum Furnace FVA-17 is a laboratory-scale vacuum furnace designed for precision vacuum heat treatment, sintering and high-temperature material processing up to 1400 °C (working temperature rated 1350 °C). The furnace features a 45 L chamber with SiC rod heating elements and a Shimaden S-type multi-segment programmable controller. It can operate under high vacuum or inert-gas (Ar/N2) atmospheres and is configurable with pump packages for deep-vacuum processes. Water cooling and an industrial chiller are required for stable high-temperature operation.

Key Selling Points

• High-temperature capability: stable heating up to 1400 °C with 1350 °C working rating.
• Accurate thermal control: Shimaden multi-segment programmable controller with S-type thermocouple for repeatable cycles.
• Deep-vacuum readiness: supports high-vacuum configurations with digital gauge monitoring to 10⁻⁴ Torr.
• Industrial-grade heating: SiC rod elements and compact 45 L chamber suitable for R&D and lab production.

Features

• High-temperature vacuum processing to 1400 °C.
• Optional 3-stage pump package (diffusion + rotary backing + roots) for deep-vacuum performance.
• Programmable ramp/soak profiles via Shimaden controller.
• Compatible with inert atmospheres (Argon, Nitrogen).
• Water-cooling requirement for body, seals and diffusion pump protection.
• Digital vacuum gauge for real-time monitoring down to 10⁻⁴ Torr.
• Optional RS485/USB PC data-logging for process traceability.

Applications

• Vacuum brazing
• Ceramic sintering
