EC Plug Fan
ELECTRICAL COMMUTATED (EC) Plug Fan
Electrically Commutated (EC) EC Plug Fan uses a brushless EC motor in a backward-curved motorized impeller. EC fans are used extensively in various applications, including computer room AC units, refrigeration condensers, and general HVAC systems. They’re also a popular retrofit option for traditional scroll fans in Air Handler Units (AHUs).
ADVANTAGES
Motor Type: The EC motor is actually a DC motor that can be connected to an AC supply line, thanks to an internal rectifier. Speed control is achieved by varying the control voltage from 0 to 10 VDC.
Efficiency: EC motors can be up to 30% more efficient than induction motors. The secondary magnetic field comes from permanent magnets, rather than copper windings.
Compact Design: The external-rotor arrangement makes for a very compact fan design.
Energy Savings: The use of electronics to convert and control the power supply offers additional power-saving opportunities.
Motor Type: BLDC (EC) motor are available.
Wheel Type: Both Aluminium and Nylon wheel are available.
Blower Housing Type: Mild Steel with Powder Coating finishing.
