VACUUM FURNACES
VACUUM HARDENING FURNACES : VHF SERIES
A vacuum Heat Treatment furnace is a type of furnace in which the product in the furnace is surrounded by a vacuum during processing. The absence of air or other gases prevents oxidation, heat loss from the product through convection, and removes a source of contamination. This enables the furnace to heat materials with superior Quality and Precision
