schedule26th Jun 17

This stainless-steel Autoclave will be used in the manufacture of large super cooled magnetic coils. It is capable of operating at a pressure of up to 6 bar gauge and down to a vacuum of 0.002 mbar absolute and is fitted with electrical heating elements to maintain a maximum operating temperature of 80 degrees C and is also externally insulated and clad. The Autoclave has been supplied with a programmable computer controlled SCADA system and access platform and has view ports in the lid and an internal lighting system to enable the curing process to be viewed at all times. 

The lid and locking ring are hydraulically operated and the lid can be opened to the vertical position to allow loading and unloading of the autoclave by an overhead crane. The working space inside is 2200mm diameter x 1900mm high. The top loading design includes an hydraulically operated door.
