The Stanford Series Grain Store variant has a selection of features that are of particular benefit for grain store, flour mills, and general food production applications:
Glass-Free Construction: Built without glass components, reducing the risk of shattering and contamination in food-sensitive environments like grain storage areas.
Ingress Protection (IP) Rating: Its high, IP66 rating, ensures dust-tight performance, essential in grain storage areas and mills.
Corrosion-Resistant Housing: Constructed from robust, corrosion-resistant materials such as stainless steel or coated aluminium.
ATEX/IECEx Certified: Certified for use in hazardous areas (Zone 2/22), making it compliant with safety regulations for explosive dust atmospheres typically present in grain handling facilities.
Impact-Resistant Diffuser: Utilises polycarbonate, shatter-resistant materials for the diffuser, ensuring durability and safety during operation or maintenance.
Optimised Light Distribution: Designed to provide wide and even light coverage, reducing shadows and improving visibility across large open areas like grain bins or silos.
Integrated Emergency: Optional Remote-test 3hr emergency provides back-up illumination in the event of a power failure, allowing operatives to safely exit the area.
