Gaseous atmospheres that may occur in areas such as tanker ships or port facilities pose a risk of explosion due to sparking or excessive heat build-up. In these situations, ex motors with special safety features are a must. That\u2019s why BEN Buchele has developed a pressure-resistant encapsulated ex motor for the highest explosion group IIC, combining powerful performance with advanced protective features.<\/p>\n

In marine applications, we can use clear definitions for hazardous zones. Critical Zones 1 and 0, where explosive atmospheres are present either occasionally or constantly, require pressure-resistant encapsulated motors \u2013 so that no spark or hot particle can escape. Our Ex motor d is designed for these requirements: it is certified for the highest explosion group IIC \u2013 this even covers hydrogen, a highly explosive and easily ignitable gas. The motor\u2019s temperature rating is also vital for certification, making sure the motor’s surface doesn\u2019t reach ignition temperature for any gas that may be present. The BEN Ex motor d is designed for class T4, with a maximum surface temperature of 135\u00b0C. <\/p>\n

Special Feature: Brake Function<\/h2>\n

This model features an integrated electromagnetic spring-applied brake with a braking torque of 3,300 Nm. This provides reliable, secure braking for applications such as anchor and mooring winches, conveyor belts or crane systems. <\/p>\n

A Unique Combination<\/h2>\n

Our pressure-resistant encapsulated motor stands out thanks to its impressive list of features: output (50 to 200 kW), frame size (280), degrees of protection (IP56 to IP68), hazardous area rating, temperature class and integrated brake function. Its robust cast iron construction makes it ideal for tough conditions \u2013 such as saltwater, salty air or extreme temperatures (from -35\u00b0C to +50\u00b0C). Depending on what\u2019s required, the motor can be supplied without a fan, with a built-in fan or with forced ventilation, supporting both continuous (S1) and short-cycle (S2, S3) operation.<\/p>\n

Customisation for 1-to-1 Replacement<\/h2>\n

One major advantage for our customers: if explosion-safety regulations change and standard motors no longer meet compliance, you won\u2019t need to redesign your entire system. True to our manufacturing philosophy, each pressure-resistant encapsulated motor is customized to your requirements, enabling smooth, one-to-one motor replacement. In most cases, your existing connections and pipework can stay right where they are. Optional add-ons such as incremental encoders, backstops, standstill heaters, relubrication systems, or bearing monitoring can be included to suit your application.<\/p>\n

Other Application Areas: Offshore, Chemical Industry, Ventilation<\/h2>\n

Along with maritime applications, our pressure-resistant encapsulated motor with brake function is used offshore, in the chemical and petrochemical industries, for gas pipeline cooling or in HVAC and ventilation systems.<\/p>\n
