Vacuum furnace FVA-15

annealingheat treatmentsintering

Overview
The Labotemp FVA-15 vacuum/atmosphere furnace provides a 36 L box chamber (300×400×300 mm) for high-temperature processing up to 1700°C (continuous operation at 1600°C). It supports pre-vacuum and inert-gas atmospheres for sintering, annealing, material synthesis and R&D workflows in laboratories and pilot production. The furnace integrates MoSi₂ rod heaters, high-temperature ceramic fiber insulation and a B-type thermocouple for precise, uniform heating in demanding applications.

Design & Control
Robust double-shell construction with built-in cooling fan, water inlet/outlet connections and reliable high-temperature sealing. Side-opening door and stainless sealing components facilitate loading and maintenance. The LCD touch-screen controller provides programmable multi-stage profiles (15 program curves, 30 segments per program, 450 total segments) with ±1°C control precision. Vacuum capability to ≤ 20,000 Pa with mechanical vacuum gauge; gas inlet/outlet ports and float flow meter for inert gas processing. Safety features include overheat protection and thermocouple-break alarm.
