Engineering Expertise Since 1983

For more than four decades, ETS has built a reputation for practical engineering support and consistent service delivery.

Operating under ISO 9001 quality management standards since 1998, our processes are structured, documented and continually improved to meet the expectations of technically demanding and regulated sectors.

In 1993, ETS became the sole UK agent for Anglentoni Industries (ACS), enabling us to supply a comprehensive range of new environmental test chambers alongside our established service capabilities.

Environmental & Laboratory Test Chambers

From our Nazeing workshop, we carry out refurbishment of climatic chambers across all major manufacturers. Our team brings together electrical, electronic, refrigeration and mechanical disciplines to ensure each project is completed to a high professional standard.

Where required, we can design and deliver complete systems in partnership with ACS – from concept through to installation and commissioning – ensuring equipment meets specification, budget and programme requirements.

Our move to a purpose-built facility has further strengthened our hire fleet and refurbishment capability, enabling us to support customers efficiently across the UK.

Our Commitment

Our guiding philosophy has always been to provide a professional, competitive and reliable service to the environmental test industry. While we are proud of what we have achieved, we continue to invest in our people, facilities and technical capability to meet the evolving demands of our sector.

Since joining ETS in 1984 as a service engineer, I have seen the industry develop significantly. Throughout that time, our priority has remained unchanged – to support our customers with practical expertise and dependable service.
