AVS-Hetherington high temperature furnace systems are used in the processing of a wide variety of products which require precise, uniform temperature in high vacuum or various high purity atmospheres for optimal yields. The furnace families are all coldwall, radiation shielded, resistance heated, bell-style batch furnaces, designed and made specifically to fit the custom needs of companies worldwide. The work and work rack are placed on a hearth and the heating element, radiation shields and chamber are lowered over the work. The refractory metal hot zones are uniquely designed and are rugged, clean and non-particulate. They allow for rapid, uniform heating of workloads from 50 to 1,500 pounds for utilization in a wide variety of applications. These furnaces have been proven over two decades of manufacture and operation to be the ultimate in high vacuum, ultra-clean atmospheres for processing metals and ceramics to demanding customer specifications.
