The Bassaire transfer hatch is manufactured from 316 grade polished stainless steel with 10mm acrylic doors and Nylon Hinges. Clever design provides easy cleaning and maintenance with an industry leading PLC controlled interlock system to aid in the reduction of cross contamination and pressure loss.
The doors are deliberately not sealed to allow a small volume of air from the clean side (normally higher pressure) to continuously flush the interior of the hatch. As the volume is relatively small it has no perceptible effect on room pressures.  
Seamless wipe clean surfaces with minimal visible fixings ensure no build-up of dirt and bacteria and our industry first “Contactless timed-release door access” system further adds to the ease of operation.
   
Available in a range of configurations to suit any application.
 
Electronic Door Interlocking
Our door interlocking system is powered by a robust industrial PLC offering reliable interlocking with adjustable* timed release for air-purge cycles. The door locking is provided by electromagnets so there are no moving parts or exposed fittings. This ensures a long lifespan and makes thorough cleaning simple.
Door unlocking is performed by simply reaching for the handle via our invisible, contactless, and wireless proximity switching. Another industry first!
The user is well informed during operation by a simple and clear traffic light system.
The entire interlock system is discreetly fitted within the walls of the transfer hatch. 
 
Operating Detail:
Using our transfer hatch could not be simpler. The door status indicator will advise you as follows:
Solid Green – This indicates that you may open the door. Reach for the handle and the door will unlock allowing you to open it.
Flashing Green – this indicates that the door is in timed interlock state and will be available after the pre-set time has elapsed. The interlock countdown is automatically triggered when door 1 is closed.
Solid Red – this indicates that the door is locked, and access will not be allowed. 
*Interlock time is factory set and must be advised prior to delivery.
