• Durable stainless steel construction • Low sound levels • Low pressure drop across diffuser • Can be installed within 2 feet of exhaust hoods 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 . The KCD diffuser works in concert with Halton VAV boxes and airflow measuring stations, combined with MARVEL+ control system to provide an integrated Demand Based variable volume exhaust and supply package with zone control for commercial kitchens. Operation and 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. The KCD design from Halton addresses both of these issues. No longer will designers have to rely on office KCD Kitchen Ceiling Diffuser building type diffusers, but can select from a series of high volume diffusers that are appropriate for kitchen supply air distribution. The system is self balancing and automatically adjusts exhaust air volumes and the appropriate makeup air requirement to each zone and/or hood and delivers it in a way that does not interfere with the cooking operation. For the first time ever the design team can provide a complete exhaust and air distribution system that is synchronized and encompasses all the design criteria needed to excel in the commercial kitchen setting.
