Our R&D team is currently testing Ex nA, frame size 225 cast iron motor with inverter. Ex nA motors of zone 2, group II (3G) are designed for potentially hazardous areas where above-standard concentrations of gas and vapor occur . The non-sparking motors are designed to prevent sparks from appearing as well as to prevent the machine surface from exceeding the permissible temperature during its operation. An innovation in the currently tested Ex nA prototype lies in the use of an inverter through which it will be possible to operate the motor and control its speed. ATB Tamel’s prototype is being tested as part of the order for the cooling and heating system fan. However, positive results of the FS 225 tests will open the way to expand our offer with other products of Ex nA range. Please click here to learn more about our current Ex nA motor offer.
