Abstract
A high temperature vacuum furnace which has an internal thermal insulation system to reduce heat losses and an external vacuum vessel which is designed to safely dissipate all heat generated within the furnace to the surrounding air. The vacuum vessel wall remains at a low enough temperature to ensure structural integrity and at a low enough temperature to protect elastomer seals without the use of water cooling.
