Hazardous Motors

What are hazardous area motors?

Hazardous motors are also known as ATEX motors (from the French Atmosphères Explosibles) and RoHS motors (Restriction of Hazardous Substances). These terms refer to a type of motor designed to be used safely even in hazardous environments where normal motors are unsuitable. This means that they are crafted not to create sparks, arcs (or sustained electrical discharge that can jump across air gaps) or overheat. This ensures they are safety compliant by reducing the risk of explosion and increasing reliability.

Where are hazardous area motors used?

Hazardous area motors are used in a range of industries, from oil and gas to mining and agriculture. They can even be used successfully in food production plants where there is a risk of dust, such as custard powder! This is because RoHS motors are crafted with more robust materials than standard area motors, including corrosion-resistant enclosures. What this means is they can withstand much harsher conditions while remaining durable and safe.

What are the benefits of using hazardous area motors?

There are many specific benefits that using hazardous area motors have over more standard motors. The first of these is that RoHS motors meet stringent safety regulations, ensuring compliance. ATEX motors also use cooling systems that provide safe working temperatures, which are maintained even in a hot environment, while also minimising the chances of ignition.

The strong seals used in hazardous area motors also block out gas and dust, and use durable gaskets. This means that by using these types of area motors, you can ensure internal safety and integrity is properly maintained.

RoHS motors are also built to be far safer than regular models. They contain safety sensors and emergency shut-down systems. These sensors and shutdown systems automatically stop the motor in the case of an issue, removing the risk of human error.

Hazardous area motors can even reduce your expenditure costs, because they are so well-suited to their environment that they’ll be far more reliable, saving money on maintenance and repairs.
