SIMOTICS XP explosion-proof low-voltage motors

The oil and gas industry is characterized by extreme demands placed on the drive technology used. This not only applies to the high explosion risk inherent in both commodities, but also to the place of deployment, whether it be offshore on the high seas, in polar regions or in the desert. The SIMOTICS XP CHEMSTAR version, designed specifically for the oil and gas industry, takes this into account. The basic and additional features are combined in such a way that the motors ensure maximum safety and plant availability while simultaneously reducing lifecycle costs, even under the extreme conditions of oil and gas production and transport.

In the chemical industry, flammable gases, liquids and solids are converted and processed in a variety of processes that are often complex. There is a risk of explosion in many different plant components, due for example to flammable solvents, or because the special work processes can produce so-called hybrid mixtures. These contain both gas and dust that is potentially explosive and have low minimum ignition energies. The motor used must therefore function continuously and efficiently, even in chemically aggressive atmospheres. In the SIMOTICS XP CHEMSTAR version, specifically designed for the chemical industry, the motor is customized precisely to these environmental conditions and thus ensures maximum reliability and safety.

The high seas are also hazardous places to work. These include offshore drilling and production platforms, as well as oil tankers, explosive chemicals or liquid natural gas (LNG), where particular caution is required. The list of hazardous locations where motors are used on such ships or platforms, both above and below deck, is long.

Below deck there are the main propulsion units, bow thrusters, azimuth drives and compressors, as well as pumps and fans for a wide variety of tasks. Hazardous locations above deck include winches, cranes, boosters and deep-well pumps. In all these locations, SIMOTICS XP motors in explosion-proof enclosures ensure maximum safety - their suitability for marine applications is underscored by the major international marine certification:

• LR - Lloyds Register (UK)
• DNV GL - Det Norske Veritas / Germanischer Lloyd (Norway / Germany)
• BV - Bureau Veritas (France)
• RINA - Registro Italiano Navale (Italy)
• ABS – American Bureau of Shipping (USA)
• KR – Korean Register of Shipping

In some areas of the food industry, fine dusts occur in silos, mills and conveyor systems, which could result in dangerous explosions. Flour dust explosion, for example, is considered to be particularly dangerous in grain processing and bread production. Our SIMOTICS XP motors with dust explosion protection Ex tb and Ex tc are tailored precisely to meet these hazardous situations. Their dust-tight enclosure - in IP65 for Zone 21 - prevents critical accumulations of dust internally. Their enclosure surface temperatures are limited to such an extent that the surrounding dust-laden atmosphere cannot be ignited. The ventilation system of the SIMOTICS XP is also designed to ensure that absolutely no sparks can occur. Special conductive paint finishes effectively prevent any electrostatic charge or discharge.
