Hedinair 200 deg°C electric twin compartment oven with rotary mandrel fixture. 

The Hedinair 200 deg°C electric twin compartment oven with rotary mandrel fixture, was originally employed for the curing of composite drive shafts, torsion bars and fuel lines for the aerospace industry. 

The design not only heats the inner chamber, but also injects hot air directly inside the tubes to provide excellent uniformity to all of the product. The chamber itself is heated by 12kW heater banks located in the lower section of the oven which is blown into the chamber via end ports.

These ports are ducted to the heater chamber so that the air first enters from one side and then repeatedly  flip flops via the PLC control and dampers to enter from the other side the back again, this also helps to maximise the uniformity of the heating profile.

The oven can be used in either manual mode or fully automatic of which 5 stored programmes are selectable from the control panel key switch.

Under automatic mode the timer can also be used to both start and stop the oven outside of the production times.

Once the programme is complete the chamber will automatically cool down with fresh air ingress, down to a minimum of 80 degrees before then opening the door automatically and indicating the "complete" status through its mimic lights. 

Although originally specifically designed for the curing of composites, this oven can be used for any application of heating, stoving, and warming of any type of cylindrical and tubular products.
