Isotherm vacuum unit is designed for heat treatment of products from various materials in vacuum and inert gas environment with adjustable speed cooling of products with a gas flow.
The heating zone of the vacuum unit is made of molybdenum. A multilayer system of heat shields made of molybdenum is used to protect the walls of the vacuum chamber. The technological vacuum chamber is water-cooled.
The heating zone consists of 3 sections. The temperature of each section is individually controlled. This allows to reduce the temperature difference at different points of the working chamber.
The system for supplying inert gas to the technological chamber provides a controlled cooling rate of products according to a given algorithm.
Temperature control at different points of the heating zone is carried out by means of 5 thermocouples
