The Harris Quick Opening Door, a proprietary design from Melco Steel, Inc., is commonly used in different types of autoclave systems. Originally developed and patented by Harris Products in the 1950's, its rights were later transferred to Melco Steel, Inc. Over the years, the design of our breech, lock-type doors have been enhanced and refined to offer safe and reliable autoclave operations.

While the other types of closures actually rotate the door against the seal/o-ring, the Harris design operates by rotating the locking ring a few degrees to expose the door lugs through cut out areas of the lock ring. Their unique design does not produce any relative motion between the door and the pressure sealing o-ring, eliminating early fatigue and the need for replacement. The door is then simply pivoted 90° to allow full access to the interiors.

The lock ring and door swing operations of our Harris doors are typically hydraulic and always interlocked to prevent operation under high-pressures. They also come with door safety interlock devices, such as mechanical, hydraulic, pneumatic and electrical interlocks to prevent inadvertent opening of the door under pressure. The safety features comply with stringent ASME requirements.
