Working closely with Trumpf and Interserve, Howorth has installed four Exflow 32 Evolution screenless ultra clean ventilation canopies, two of which were combined into a single space, creating a 'barn theatre' at Leighton Hospital, part of the Mid Cheshire Hospitals NHS Foundation Trust.
Barn theatres are widely used in Europe, and are becoming increasingly popular in the UK. They offer benefits in terms of infection control and space-efficiency, as well as offering enhanced opportunities for teamwork and expert supervision. The screenless Evolution is particularly suited to the barn theatre design, as it provides a stronger entrainment performance than screened models within the barn theatre set up.
Since its introduction in 2012, over 120 units have been manufactured. The Evolution essentially retains the basic construction of Howorth’s standard Exflow model, but with some innovative engineering at the air discharge, the company has recreated, and in many ways improved, the performance of the systems without the need for the traditional partial walls.
At the core of this new product are the patented Passive Coanda and Active Coanda systems. These are unassisted (Passive) or assisted (Active) air displacement devices, designed to replicate the controlled airflow of a solid side screen.
