ravenscroft logoHealthier Air - Energy Saving

Ravenscroft specialises in providing innovative and energy efficient engineering solutions for the heating and ventilating sector. Our customised engineering solutions yield high quality indoor air while reducing HVAC operating costs.  


For the Rock at the Wellington International airport, Ravenscroft supplied custom made displacement diffusers, which were used to supply low velocity air directly into the occupied zone. To confirm the required performance of the custom diffusers, they were factory tested with the proposed slotted ply facades.


Behind the architectural facade are two Halton AFA displacement diffusers (below).
