Elmac Technologies’ light-duty flame arresters deliver safety and cost savings

Elmac Technologies, the acknowledged international leaders in flame and explosion safety systems, have developed a range of in-line and end-of-line deflagration flame arresters especially for light-duty applications.

Each model provides a low cost solution for applications where a simple lightweight product is required.

Microbore in-line light duty arresters (MB-IB)

End-of-line light-duty arresters (SVE and SV range)

Gas Groups

MB-IB in-line and SVE/SV end-of-line deflagration arresters are suitable for use with gases in Groups I, IIA, IIB1, IIB2 and IIB3.

Comments Elmac Technologies’ Managing Director , Dr. Martyn Cooling, “Since we introduced the light-duty explosion protection range of flame arresters, numerous organisations have selected them for their compact design and particular suitability for gas purging, sampling line and analysis applications. Purpose-designed for less demanding tasks, they can also offer considerable cost savings.”

The benefits of using Elmac Technologies’ light duty-flame arresters include:

•  Range of sizes: 15mm to 50mm NB for SVE/SV and 15mm to 20mm NB for MB-IB
•  Suitable for gases with MESG > 0.65mm (gas group IIB3)
•  Lightweight - SVE in carbon steel or stainless steel housings SV in zinc or aluminium alloy
•  BSP/NPT male or female screwed connections in accordance with ISO7-1 and ISO7-2
•  Optional weatherhood for environmental protection
•  Technical advice on specific location queries

About Elmac Technologies

In 2008, Elmac Technologies will celebrate sixty years of expertise in the design and development of flame arresters for use in the worldwide gas processing and distribution industry, and can proudly claim to be the technical leader in flame and explosion safety systems.

Originally known as Elmac Engineering, the company developed its first flame arrester in 1948, for use with town gas, and rapidly established a global reputation for the design, manufacture and supply of products to enhance process safety in a broad range of industrial sectors. These sectors include the global oil, gas and petrochemical industries; bio-fuels, mining, pharmaceuticals and power generation; agro-chemicals and fertilisers; distillers, food, flavours and fragrance companies; waste treatment organisations and special equipment manufacturers (OEMs).

Acquired by KnitMesh in 2001, and re-branded 'Elmac Technologies' in 2007 to reflect better the high levels of innovation and enhanced protection offered by its products, Elmac Technologies has grown to become one of the premier brands in the global market for flame arresters.

Elmac can assist clients by specifying appropriate products for proposed new installations and plant retrofits. In addition, Elmac are able to provide advice on the positioning of these products in an installation and to evaluate the suitability of flame arresters already fitted. To support clients in meeting the 2006 EU ATEX Directive for flame arrester compliance, the company is also willing to undertake site visits to discuss existing installations and to provide technical presentations to enhance awareness amongst the engineering community.

With state-of-the-art commercial, manufacturing and test facilities in the UK and additional manufacturing centres in South Africa and the People's Republic of China, Elmac Technologies is rapidly developing a comprehensive range of enhanced in-line and end-ofline deflagration arresters and in-line unstable detonation arresters. These devices are suitable for use in gas groups IIA, IIB3 and IIC having been rigorously tested in accordance with BS EN 12874:2001. The high-tech testing facilities can also be used to conduct experiments to demonstrate that proposed technical solutions meet client-specific requirements.

Elmac is also able to draw on the benefits of Computational Fluid Dynamics (CFD) to model the behaviour of a system in order to investigate the flow behaviour, including the study of flow patterns and the prediction of pressure drop. This information can be used to optimise designs for particular applications whilst avoiding the need for costly plant trials.
As part of an international group that also includes global knitted mesh specialists, KnitMesh Technologies, Elmac enjoys the financial stability necessary to continually innovate, research and develop the flame arrester solutions that will help bring greater safety to industry worldwide.
