LOHER低压防腐电机

Chemstar Motor Surface-cooled motors according to IEC and VIK up to frame size 355 and approx. 315 kW Overview General description Technical data overview Features Customer benefits Typical applications General description The Loher Chemstar Motor is at home in the chemical and petrochemical industry. For low and medium power ratings, the Loher Chemstar series especially guarantees a maximum degree of safety, the highest level of availability and low operating costs. For power ratings up to 315 kW, this motor is the ideal drive component - as it fulfills all of the demands and requirements of the chemical and petrochemical industry. A sector-specific design takes into account the location - not only for hazardous zones (explosive areas) but also in non-hazardous zones. For instance, a high-quality paint finish and galvanized fan cowl protect against aggressive atmospheres. Anti-condensation heating is often no longer required even for extremely high air humidities. Loher Chemstar motors operate perfectly at temperatures from -55 °C up to +70 °C. These motors are even optimally suited for operation in desert and polar regions. When required, these motors can be equipped with corrosion-resistant stainless steel screws and bolts. Shaft seals in IP66 protect against water and dust. The degree of protection extends up to IP67. The enclosure is manufactured out of rugged gray cast iron and is therefore extremely resistant to corrosion, dampens vibration and has a high strength. Reinforced bearings and PTC thermistors - no problem. These adapted motors fulfill almost all user requirements and specifications.
