In 1999, the BESA (HVCA) Standard for Kitchen Ventilation Systems (DW/171) was introduced to the industry. In 2005 it was revised and rebadged as DW/172 Specification for Kitchen Ventilation Systems. Since then it has sold over 6000 copies. More importantly, it has become widely acknowledged as the authoritative specification for kitchen ventilation design throughout the UK and many parts of the world.
Like any specification, however, it needs to be revised in the light of new thinking, technical advancements and innovation. This review process has now been completed by the BESA Ventilation Group and the 2018 version of DW/172 has been updated to reflect current legislations and the latest cooking techniques and design of catering equipment, by all sections of the catering industry.
Among the many amendments and clarifications contained in the new document, the following are worthy of particular note.
• The appliance Coefficient Schedule has been significantly expanded and modified
• Modification to Grease Separation
• The lighting section has been modernised
• New section for Solid Fuel Equipment
• New section for Demand Controlled Kitchen Ventilation systems.
• Gas Interlocking
• Modifications to Pollution Control
• New section for Recirculation Systems
• Modifications to Cleaning and Maintenance
• Control Panels
All other sections have been revised and updated in the hope and expectation that BESA’s Specification for Kitchen Ventilation Systems DW/172 (2018) will continue to be widely used and respected by all sectors in the catering industry.
