Trolex Engineering, pioneers in the design and manufacture of electro-mechanical machinery for oil and gas exploration, are pleased to announce the launch of their new website.
Coinciding with the launch of the new brand, the fresh-looking website has been built to deliver a user-friendly, easy-to-navigate, informative and interesting platform, containing a range of useful information, including technical details about the complete range of products, applications and market information as well as topics of interest such as the function of a slip ring, certification and ingress protection.
In addition, the new website is mobile and tablet responsive allowing you to download any information required, wherever you are.
Visitors can stay up to date with the latest news from the company, and the offshore industry in general, using the RSS feed on site. The news from the website is distributed to the company’s LinkedIn and Twitter accounts allowing multiple ways to view news about the company.
Trolex Engineering have been designing and manufacturing slip ring units for almost 4 decades, with customers in over 49 countries. Their products carry ATEX and IECEx certification, making them suitable for operation in hazardous area applications.
We have been shortlisted in the category of International Trade at the Stockport Business Awards. The awards ceremony takes place on 2nd October 2014, where the winner will be announced.

The IP classification system designates by means of a number, the degree of protection provided by an enclosure against impact or dust and water ingress. Please note that the IP classification should not be construed as indicating corrosion resistance.
Degrees of Protection to IEC 529
Oil, gas and mining applications require explosion-proof certified products such as slip rings. These certification requirements are defined by the certification body and are divided into explosion groups, zones, product groups and temperature classes.
Potentially explosive atmospheres are divided into 6 zones; gases and vapours are placed in Zone 2, 1 and 0, in increasing order, whilst dust are placed in Zones 22, 21 and 20, in increasing order.
Product groups are defined as Group I and Group II. Group I is usually used for underground applications such as mining, for the prevention of gas and dust explosions, usually from firedamp. Group II normally covers all other hazardous applications. Within these groups, there are 6 categories; 1G, 2G, 3G, 1D, 2D and 3D. G is for gas explosion protection, whereas D is for dust. Therefore, 1G, 2G and 3G are equivalent to Zones 0, 1 and 2, and 1D, 2D and 3D are equivalent to Zones 20, 21 and 22.
Explosion groups apply to gases and vapours, and is a means to measure the gases' ability to ignite. It is divided into three groups, in increasing order (IIA-IIB-IIC) according to the type of protection being used.
Temperature classes are divided into 6 classes and only apply to Group II applications. The classes are listed as T1 - T6 in increasing order of temperature; 450, 300, 200, 135, 100, 85°C. This figure is the maximum permissible surface temperature of the equipment in relation to +40°C ambient temperature on any surface area, and should not be exceeded at any time.
