Toshiba’s Petrochem SD+ Medium
Voltage Motor – Rugged Construction
for Ultimate Durability.
This totally enclosed fan cooled motor package offers
severe duty IP55 protection for the toughest material
processing applications such as compressors, pumps,
fans, and conveyors. Its low temperature and low
vibration design provides additional durability to withstand
these harsh environments, decreasing maintenance
requirements and chances of failures while ultimately
increasing the motor’s lifespan. Built with certain IEEE
Std. 841™ -2009 specifications, Toshiba’s Petrochem
SD+ motor is the ideal solution for the oil and gas, mining
and mineral, and pulp and paper industries.
