Explosion Proof Machines for hazardous areas Series ET and CAD: safety, reliability, protection Nidec ASI offers a wide range of engineered-to-order electric machines to meet customers demanding specifications. For hazardous areas we designed two special machines: Series ET and series CAD. Series ET is the ideal solution for Ex d areas and is certified for Group IIB + H2 classified areas. Series CAD is ideal for installation in hazardous areas where Ex d IIB T3/T4 (IEC standards) protection is required. His external cooling fins and internal fans, streamline air flow for optimum cooling. This optimized cooling system and the special electromagnetic design that went into making this series also make series CAD suitable for variable speed drive applications. Hazardous area machines – Series CAD/ET Power rating: 150 – 4,500 kW 200 – 6,000 HP Voltage: up to 7,2 V Our standard explosion proof protection is: EEx d IIB T3/T4 Sleeve or antifriction bearings available EEx d IIB H2 or IIC upon request.
