FLAME-PROOF MOTORS (ET)
NIDEC FLAME-PROOF MOTORS (ET)
Series ETSeries ET covers totally enclosed, selfventilated machines with Ex d flameproofcasing and built in air to air heat exchanger.
The heat exchanger consists of a bank ofcorrosion resistant steel tubes which aresituated around the stator core.
Ambient air is forced through the tubes by anexternal shaft mounted fan.
Two internal shaft mounted fans circulate the primary(internal) cooling air through the activeparts of the motor and the tube bank.
The tubes are carefully assembled and sealed to meet the required standards for flame proof applications.
