They can be supplied in the standard rated voltages 230/400 V, 400/690 V and 500V. The basic version also features the higher degree of protection IP56, giving it greater protection from water. This means that it meets most of the technical specifications in heavy industry. Motor versions up to IP66 are possible where protection requirements are greater. The standard option package has been expanded to include extra options such as anti-condensation heating and now features enhanced connection systems and excellent noise levels in order to meet additional project-specific requirements. The motors are available with ratings of between 0.25 kW and 315 kW and shaft heights between 71 and 355. The documentation is already available during the engineering phase, which saves time and money. Loher Chemstar motors have all the required explosion protection systems and are extremely cost-efficient thanks to low energy consumption, reduced operating costs and long service intervals. In type of explosion protection Ex n und Ex de, they are certified across the board also in IEC Ex.
