CE Marked (UKCA pending) – KCD diffusers are designed to provide for high volumes of makeup air at very low velocity. They are particularly suitable for delivering the makeup air in small kitchens or used with Halton’s M.A.R.V.E.L. energy saving technology.
Uncontrolled draughts – even the smallest ones – can totally ruin the Capture & Containment capacity of hoods and ventilated ceilings. A well designed make up air strategy contributes not only to guarantee this efficiency but also to the final Indoor Air Quality (IAQ) inside the kitchen. It should always be considered as an inherent part of the kitchen ventilation solution.
Halton’s KCD ceiling diffuser has been specifically designed for kitchens. It provides for a high volume of supply air ideally at 60 cm minimum of the hood(s) without disrupting hood performance. Tested performance of supply air discharge ensures that airflow, pressure drop, and NC (Noise Criteria) specifications are met.
KCD diffusers are particularly suitable for small kitchens, especially when they are equipped with Halton’s M.A.R.V.E.L. (Demand Controlled Ventilation). This technology constantly adjusts the exhaust airflow rates depending on cooking activity as well as the associated supply airflow rates. KCD diffusers have an excellent reaction to variable airflows.
