On request, the fan is available with IP68 water and dust protection. EC technology is based on a DC motor that has an integrated AC to DC converter. The device, which consumes 70% less power than an AC shade pole motor, offers multi-speed control, a low acoustic level and a long motor life in a compact solution.
The EC Axial Fan is available in two sizes: 120x38mm and 250x78mm. The former is suitable for small cooling fans, while the latter is suitable for larger evaporator/condenser fans, allowing for high/low speed switching with day and night operation via customer control circuit.
According to DoE research, evaporator fan shutdown is a leading technology that will be very efficient for energy savings for refrigerators. Applying EC fans to refrigerators will be a key success factor in reducing total power loss. In 2015, power-saving refrigerators were included within ENERGY STAR´s Most Efficient Criteria programme, which is dedicated to identifying highly-efficient products in the marketplace.
