Our annealing furnaces are constructed of panels with Louvres for air exchange and a tubular frame. General maintenance interventions are easier with a tubular system.

Heating muffles are made of resistance and unique, highly thermally efficient refractory insulating panels. Strong temperature changes can be resisted by special stainless steel heating chambers.

Protection gas enters the chamber through nozzles. The de-oxidation process is improved by a burner placed in front of the chamber to prevent oxygen entry. Inside is a shovel made of stainless steel.

When annealing metal, you simply push the pale to the bottom of the cooling chamber and drop it into the water tub for instant cooling (or leave it lying in the cooling chamber to cool, taking some time). The tub's treated material is removed either manually or (optionally) with a pneumatic piston.
