Chamber oven

bellrotary retortsintering

Overview
Large industrial ovens and furnaces designed for production and heavy-duty applications. Furnaces can be specified with hard-wearing chamber hearths and higher-rated heating elements to accelerate heat-up and extend component life.

Production furnaces
Production furnaces with maximum operating temperatures up to 3000°C can be custom built to meet process requirements. Options include continuous production layouts, fast loading/unloading and integrated quality-control features. To minimise downtime during cool-down, production furnaces are often fitted with interchangeable twin hearth plates or twin retorts so one unit cools while the other is loaded.

Loading of heavy loads
Manual or automated loading trolleys are available on request. Advanced loading systems can be supplied to handle heavy or bulky components and to integrate with plant automation.

Annual service contracts
Annual service and maintenance contracts are available to reduce unplanned downtime and to preserve furnace performance and safety.
