VI – Series

VI – Series

The Linn High Temp – VI Series is a gastight, continuous working furnace designed for operation under controlled atmospheres, specifically tailored for the heat treatment of small and delicate parts. It features a shaker hearth transport system, which gently moves items through the furnace while maintaining proper orientation—ensuring each part undergoes consistent and uniform quenching. This system is particularly effective for components that cannot be conveyed on traditional belts due to the risk of jamming.

The furnace is insulated with refractory light stones on the side walls and bottom, supported by microporous back insulation, and a ceramic fibre board roof for optimal thermal efficiency. Heating is provided by metal alloy spiral heaters wound on ceramic tubes, ensuring uniform temperature distribution. Temperature is accurately monitored using a Type K thermocouple in a ceramic protection tube. The VI Series is ideal for continuous processing of small precision items where uniform treatment and controlled atmosphere are critical.
