The High Vac vacuum kiln features a rectangular housing adapted to the lumber stack with uniform steam accumulation chambers. Under vacuum, the water bound in the lumber evaporates easily and fast. This reduces drying time significantly and helps prevent drying defects. Hildebrand has developed the new steam pulsation process for lumber species and dimensions that are otherwise difficult to dry. The process alternates between saturated steam and superheated steam environment with rest phases and reconditioning in between – ideal for fast and stress-free lumber drying of softwood and hardwood.

All Hildebrand kilns meet the highest quality standards: highly insulated aluminum or stainless steel construction, fans specially developed for Hildebrand, and all purchased parts from renowned and certified suppliers.
