Furnaces increase the value of precious gemstones
Elite Thermal Systems have won a contract to develop an 1800C furnace that will produce gemstones that are significantly clearer, thereby increasing their purity and value
Special oven for corrosive materials
An unusual application presented a challenge to Elite: it was for a leading international photographic manufacturer, who required a special 450 degrees C oven for the production of barium bromide
The oven incorporates a 110mm reaction tube with a 600mm heated length.
Elite designed a special carrier assembly to insert the wafers into the heated zone of the system.
The carrier is passed into the heated zone of the reaction vessel by a gas tight manual push-pull rod mechanism.
They are then processed under a high purity hydrogen/nitrogen gas mixture controlled by flow meters and micro filters.
Loading and unloading of the wafers onto the carrier assembly is facilitated by a precision slide assembly, which allows the whole carrier slide and push rod assembly to be withdrawn clear of the reaction tube.
Alf Roberts, Managing Director of Elite said, "This was a challenging project due to the need to keep a clean and pure environment for the wafers".
"We are producing many more innovative designs to meet the needs of the opto-electronics market that have a very high degree of precision and sophistication", added Alf.
Elite produce a range a standard ovens and furnaces up to 2000 degrees C, which are suitable for many applications.
Where specific thermal process characteristics are required, Elite will design a custom solution to meet the needs of the system.
