IP68-rated fans for food & beverage equipment

Cleanliness and sanitization of equipment is vital for food safety in food and beverage applications . When production downtime for cleaning threatens the supply chains for products and services that society depends on , solutions must be found . The ability to clean equipment while in service without requiring extensive downtime or disassembly is critical to productivity and commerce . IP68-rated components permit the cleaning of food and beverage equipment to prevent contamination .
Components exposed to harsh environments , including fluids and cleaning chemicals , are susceptible to failure over time , with cooling fans being no exception . The classification of the insulation system is based on the lowest rated component in the system , and in many instances , this may be the fan . The materials and parts specified in the construction that affect the insulation class include the motor winding , the wire and the insulation on the wires , the enamel coating on the magnet wire , as well as the visible parts of the fan or fan tray such as the frame and impeller .
IP RATING SYSTEM Equipment used in food and beverage applications , from commercial kitchen appliances and fountain drink dispensers to automation equipment in the manufacturing process , employ fans that require regular intensive cleaning with both high pressure and high temperature water . Washdown procedures prevent debris or microbial bacteria from forming to ensure public safety .
Traditionally , fans were vulnerable to damage from intensive cleaning due to their electronic circuitry and moving parts . Recent developments in conformal coating technologies have enabled Orion
