The KCD diffuser works in concert with Halton VAV boxes and airflow measuring stations, combined with M.A.R.V.E.L.+ control system to provide an integrated Demand Based variable volume exhaust and supply package with zone control for commercial kitchens.
The Halton model KCD Kitchen Ceiling Diffuser provides for a high volume of supply air ideally within 2 feet of the hood(s) or flush mounted with the hood without disrupting hood performance. Tested performance of supply air discharge ensures that airflow, pressure drop, and N.C. specifications are met.
Kitchen Ceiling Diffuser Features & Benefits
Durable stainless steel construction
Low sound levels
Low pressure drop across diffuser
Can be installed within 2 feet of exhaust hoods
Operation & Description
With Demand Controlled Ventilation (DCV) becoming the norm rather than the exception, managing the changes in exhaust and supply air volumes for a specific group of hoods (or zone) has been a challenge.
The M.A.R.V.E.L.+ system is unique among DCV systems as it measures exhaust rates in each hood and the associated supply air in real time. This capability ensures that proper space balance is maintained as the system varies the exhaust airflows during operation. The majority of capture and containment problems occur because of two issues:
high velocity discharge from diffusers (such as 4-way louvered diffusers) causing poor hood performance
unbalanced supply air in kitchens around hoods.
