The new iQ-one EC motor from ebm‑papst meets all these requirements and can also be combined with an aerodynamically optimized fan impeller.
Fans are now indispensable in supermarkets, as compact refrigerated cabinets can only operate with their help. A few years ago, shaded-pole motors were still the standard for driving the fans, as they are economical, robust and durable. However, their poor efficiency levels can no longer be tolerated today.
In addition to the energy-saving fans already established on the market for refrigeration technology, ebm‑papst has now developed the new iQ-one EC motor, which enables an output power of up to 5 watts for easy like-for-like replacement of existing Q or shaded-pole motors. Compared to conventional Q motors, it has a high motor efficiency level of 50% and operates at full power with low noise characteristics. It is designed for all typical supply voltages and can therefore be used worldwide. The iQ-one can be combined with different fan impellers of sizes 154, 172 and 200 mm. It is an efficient fan solution for a wide range of applications, especially with the aerodynamically optimized fan impellers in sizes 172 and 200 mm. Particularly in supermarkets, where many fans operate continuously, the potential energy savings are especially high.
A further major issue with regard to refrigerated cabinets is the refrigerant used. Modern refrigerants must be safe for the environment and have a low global warming potential, whilst at the same time providing good refrigeration performance. Regulation (EU) 517/2014, also known as the Fluorinated Gas Regulation, has been in force since January 1, 2015. Alongside ammonia and CO2, natural refrigerants such as isobutane, propane, and propene are becoming increasingly popular as an ecological alternative to (partially) halogenated refrigerants. When malfunctions occur, however, the non-toxic hydrocarbons can form readily explosive mixtures with air. As standard, the new iQ-one EC motor meets the European standards EN 60335-2-24 (household appliance standard - Particular requirements for refrigerating appliances, ice-cream appliances and ice makers) and EN 60335-2-89 (household appliance standard - Particular requirements for commercial refrigerating appliances and ice-makers) in order to provide a safe cooling solution in this sector.
