HETHERINGTON H2 / VACUUM FURNACES
The Hetherington bell-style furnace brand was purchased by AVS in 2005. Hetherington furnaces feature bottom-loading, electro-polished chambers for operation in high vacuum (10-6torr) or partial pressure gas atmospheres such as argon, nitrogen and wet or dry hydrogen. The all stainless steel, molybdenum or tungsten hot zones are particularly suitable for applications intolerant to particulate contamination, such as medical or semiconductor production. In addition to manufacturing new Hetherington furnaces, AVS offers continuing aftermarket service to all original Hetherington furnace owners, and also upgrades to contemporary instrument and control technologies.
