PCME changes name to ENVEA UK Ltd



PCME, a leading specialist in the development, manufacture and supply of continuous in-stack particulate emission and velocity measurement monitors is pleased to announce that it will be changing its Company name to ENVEA UK Ltd, trading as ENVEA, from the 1st January 2019.

Having been acquired in 2014 by Environnement S.A, this is the penultimate piece in the rebranding jigsaw as all the Group’s businesses come under a single ENVEA brand. Under the strapline Knowledge in Action, ENVEA is looking to utilise its wide ranging intellectual property on the global stage in the areas of industrial process measurement, continuous emission monitoring, mercury monitoring, ambient air quality monitoring, engine exhaust gas monitoring, radionuclide monitoring, environmental data acquisition and processing software.

It’s largely business as usual but as ENVEA UK Ltd.’s Managing Director, Chris Shelley points out this signals a new chapter in the Company’s near 30 year history. “We have had several years of unprecedented growth which we want to consolidate upon to ensure a sustainable future”. Technology and product innovation as well as maintaining a reputation for excellent customer support are the key to that future growth. “This move also means that customers, distributors and system integrators alike will benefit from the Group’s broader expertise arising from its diverse portfolio of products leading to better total solutions” added Chris.

Founding chairman of air-quality monitoring company celebrates 40 years in business by sharing nearly €2million among employees

The founder of a successful French air-quality monitoring company is celebrating 40 years in business by giving every one of his 600 staff 40 free shares worth about €3,000.

François Gourdon, the 70-year-old founding chairman of Environnement SA, surprised staff with the news of the gift, which will cost about €2million at a 40th anniversary party at a club near Place de la Concorde on Thursday, reports Le Parisien.

Staff based at head office in Yvelines, as well as India, the UK, US and China are all set to benefit.

The company produces monitoring stations capable of detecting particles in ambient air, gas emissions or dioxin levels around incinerators, thermal power plants or chemical sites. Its next big contract is to supply monitoring stations in Qatar, which will host the 2022 football World Cup.

From July 1, the name of the company will change to Envea, nearly 40 years to the day after it was founded with just three employees.


Within its development strategy and desire to unite its technologies, production sites and sales subsidiaries, the Environnement S.A Group is introducing its global commercial brand envea™. The Group hopes to provide a more complete vision of its monitoring solutions, for the benefit of its customers, together with its high added value services. Its high precision monitoring analyzers allows the compliance with current environmental regulations and contribute to the optimization of industrial processes for a better efficiency, raw materials and energy savings, reduction of environmental impacts…

Following the development of its new range of “eco-designed” ambient air analyzers, the company has setup a new organization focused on its three core businesses: Ambient Air, Industry & Process, and Emissions. The Group is accelerating its organic development and growth through an ambitious unified Research, Development & Innovation program, and is also continuously targeting first-class acquisitions.

Undeniably, with the arrival of companies such as PCME Ltd (UK) – continuous particulate emission measurement systems, flue gas flow meters and devices for measuring the performance of industrial filtration systems – SWR engineering Gmbh (Germany) – systems for the detection and measurement of bulk solids – and TDL Ltd (UK) – gas analyzers based on the use of high-resolution lasers – synergy is materializing! Projects and skills are being combined, streamlining and accelerating the development of the most advanced analysis technologies for gas, flow and particulate measurements.

François Gourdon, Environnement S.A’s President, affirms: “The assertion of our visual identity and the deployment of the enveaTM brand, support our global development strategy and growth ambitions in both our traditional and complementary markets. Our objective to reach an annual turnover close to € 80 million is about to be achieved, the group is preparing to exceed its target of € 100 million by 2020.”

The launch of its commercial brand is an exciting and significant milestone in the Group’s history, which will be celebrating its 40th anniversary this year.

UK steel industry embraces new technology

TDL Sensors Ltd real-time, in-situ, multi-gas analyser installed to monitor a high temperature, high dust load steel manufacturing process.

Interesting to read BBC's Roger Harrabin piece Steel jobs 'can be saved by tech', says energy researcher.  He was referencing The University of Cambridge's Professor Julian Allwood report on the future of the UK steel industry.  From our experience over the last two years working on a project to design and install a real-time multi-gas laser analyser on a steel manufacturing process, we have seen a willingness within the UK steel industry to embrace new technologies that can improve efficiency and productivity.
