Box ovens

A box oven is typically used with manual or Power & Free conveyor systems where heat treatment is a part of “step by step” finishing process.

Box ovens are also used as standalone units into which the workpieces are transported for heat treatment using e.g. rollers and pallets or suspended directly from overhead fixture points mounted in the oven chamber.   

AABO’s box ovens are available for use at several temperature points. This means that these ovens are available in a variety of different insulation layers and constructions. 

  • 0 – 100 °C:     100 mm
  • 100 – 250 °C:  310 mm
  • 250 – 550 °C:  450 mm

AABO’s box ovens are designed with a ‘floating’ internal core, suspended using a minimum of contact points to the external bearing construction. This minimises the development of a heat bridge.

AABO’s box ovens are all based on the convection principle which ensures optimum energy utilisation.

Heat is injected into the lower section of the oven chamber either through air ducts in the floor or in the walls. The air is recirculated from the top of the oven chamber across a heating unit. This ensures correct and optimum thermal air distribution as well as uniform heat transmission to the production items. 

AABO’s box ovens can be heated using:

  • Gas
  • Oil
  • Electricity

AABO’s box ovens are available with:

  • Direct heating
  • Indirect heating

AABO’s box ovens are available as:

  • “Sluice” ovens where workpieces are transported through an air lock located at the entry to/exit from the oven chamber
  • Door ovens where workpieces are transported through a revolving or sliding door located at the entry to/exit from the oven chamber The doors are available either as manually operated or fully automated doors
