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.
