Words from Our Installation Experts

Over the past few years, many of our rotary doors have been installed where the added feature of atmospheric isolation is utilised; many pharmaceutical and bio-technology processes require a degree of environmental isolation - either the air content of the room needs to be preserved at a pre-determined level, or the air pressure, either positive or negative, needs to be kept within a certain tolerance, which a conventional opening door would not allow.
Increasingly, critical pharmaceutical processes, DNA or chemical compound analysis, or compound/catalyst isolation require a degree of isolation room to room. Non-destructive testing using light-sensitive X-Ray materials, atmospheric ‘holding room’ conditions, conventional clean room isolation applications - new applications are appearing all the time.

Our rotary doors are available in wipe-clean gloss white for basic clean air applications, or wipe-clean primary colours suitable for industrial micro-technology production applications.

Contact our design engineers to consult with us as to the suitability of your requirement to our doors.  Because we have been manufacturing this design in large batch quantities for many years, pricing is sensible whilst reliability in use over many years has been proven in thousands of installations world-wide.  Two of the most recent prestigious installations are at the MRC Laboratory of Molecular Biology at Cambridge, and at the new PCO facility at Rolls-Royce, Derby.
