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.  

The new catering school at the Nelson campus of the Nelson-Marlborough Institute of Technology (NMIT) has been outfitted with Halton model KVF kitchen exhaust hoods throughout. The consultants Aurecon (formally Connell Wagner) selected Halton based on two main factors - energy efficiency and reduced airflow. With the kitchen being located on the ground floor of a three storey building, the size of the vertical supply and exhaust ducts was a major issue.

Halton KVF hoods typically require only 50-65% of the exhaust airflow in comparison to standard exhaust hoods. Consequently the make-up air requirements are reduced by the same amount, leading to smaller supply and exhaust ducts and fans. On a large project such as this, the ongoing savings in fan running costs become significant.

A further benefit is the lower noise level which is a real plus in a teaching situation. Halton have a deserved reputation of being the quietest exhaust.
