Electric motors used in the petrochemical industry

There is a sector within the chemical industry that focusses on petrochemistry. This particular branch of industry is engaged in the processing of petroleum and ensuing products. Petrochemical engineering is mainly applied in oil refineries. You’ve undoubtedly reached the same conclusion as we have; if this isn’t an explosive environment for electric motors, what is? It is, therefore, important that the electric motor meets all kinds of requirements. At Kolmer Electric Motors we know better than anyone else what requirements must be met for electric motors within the petrochemical sector. We are happy to help you with your pressure-resistant motors.

Pressure-resistant ATEX motors

In the petrochemical industry they make use of a great variety of pumps. One of the requirements is that all these pumps must be equipped with pressure-resistant ATEX motors. ATEX stands for ‘ATmosphère EXplosible’ (Explosive Atmosphere). This comprises two European directives on explosion hazards under atmospheric conditions. As of 1 July 2003, European organisations must comply with the ATEX 153 directive and the ATEX 114 directive, when the risk of explosion exists. The ATEX 114 directive is especially targeted at equipment used in places where the risk of an explosion is imminent. If the installation prescribes a motor of the pressure-resistant variety, the construction of the housing of the electric motor must be designed in such a way that the motor does not present a danger to the environment in the event of an internal explosion. All these pressure-resistant motors are individually inspected and approved by an independent party, the so-called notified bodies.

Collaboration with CEMP

Over past years Kolmer Electric Motors has gained a lot of experience in the field of ATEX. The intensive collaboration with CEMP (manufacturer of pressure-resistant electric motors) is a good example of this. CEMP is a renowned brand in the field of electric motors. By combining our experience and knowledge with the knowledge and skills of CEMP, many customer-specific solutions have already been devised.

Kolmer Top Coating

An engine that does not flake and does not rust, that is our goal when we start an extensive research project in 2016. We develop a coating that does hold and the test results exceed all expectations. Engines keep looking great year after year, no matter the conditions. TNO is testing the safety and we are now fully in production. Kolmer Top Coating anchors itself through the paint layer in the underlying aluminum and cast iron. A water-thin, super strong layer that protects for years and can be used on all our Cantoni and a selection of EMF and Cemp engines.
