Double Ended Clean Room Oven To A Customised Design

When a leading manufacturer of highly innovative stainless steel arterial stents came to Carbolite to buy a clean room oven, they required something rather different from the standard design.

Although only required to reach a maximum of 400°C and to operate in a relatively conservative class 10,000 clean room environment, some of the other vital statistics were considerably more rigorous. A chamber nearly a metre and a half deep needed heating with an accuracy of better than ±1°C and a uniformity better than ±5°C. This was achieved using a fully programmable controller tracked by three slave controllers to provide 4 zone temperature control within the oven chamber.

A specially designed load management system carried the stents for heat treatment on mandrels and was designed so that it could be rolled straight from a trolley into the chamber. Untreated product could be loaded into one end of the chamber and unloaded into the clean room through the door at the opposite end
