Containerised Test Systems
Sue James • May 7, 2020
JTS Ltd specialises in designing and building systems for temperature, humidity, rain, dust and vibration testing, with units ranging from small bench-top chambers to walk-in rooms, and air conditioning units to supply independent test rigs.

We work closely with our clients to build test solutions for individual company requirements, often involving innovative approaches.
One such project, currently, is for University of South Wales' Centre for Automotive and Power Systems Engineering (CAPSE). The team there are working with major companies to test new battery technologies, not only for the automotive industry but for National Grid and renewable energies too.
JTS has to date converted twelve 30 ft shipping containers into specialist self-contained ‘test cells’ for temperature and humidity testing at CAPSE’s Pontypridd site. Battery testing can be highly volatile and to minimise risk in this case, JTS engineers designed an innovative CO2 cascade system, capable of achieving a range of +80 / -40c at high rates of temperature change. As an inert gas, CO2 has a major advantage in this application over alternative refrigerants which are either highly flammable, less efficient or have a far higher GWP (Global Warming Potential).
Our relationship with CAPSE is ongoing, providing support and maintenance, and we’re now looking into training USW personnel to carry out simple troubleshooting and maintenance.
Working closely with clients ensures the best outcomes for individual test needs, whether the requirement is for standard or bespoke chambers, containerised systems, or walk-in rooms. With experience across a wide range of industries, and a client base including manufacturers such as Dyson, BAE Systems, TRW Automotive and Red Bull, we are ready to help you achieve the best environmental test solutions for your products.
Contact us if you have a special requirement, or are interested in knowing more about our containerised systems.

What does “Made in Britain” mean to us? It means engineering expertise, quality, innovation and pride in what we do. Based in Wales, JTS designs and manufactures environmental test chambers, providing engineered test solutions that are designed and built right here in Britain. π We’re proud to be an employee-owned company, meaning the people who design, engineer, build and support our products have a genuine stake in the business and its future. We’re also proud members of @MadeinBritain the registered trademark supporting and promoting British manufacturing excellence. For us, buying British isn’t simply about where a product is made. It’s about supporting the people, skills, businesses and communities behind it. It helps strengthen UK manufacturing, supports local employment, preserves valuable engineering expertise and encourages the continued development of British innovation. ο»Ώ So, this Buy British Day, we’re celebrating the people who make it happen — from the engineers and designers to the skilled hands on the shop floor. Designed in Wales. Engineered in Britain. Built for the world. π Here’s to British manufacturing — and to keeping great engineering skills, innovation and jobs right here in the UK. π¬π§

At JTS, being an employee-owned company means looking after one another isn't just a value – it's part of who we are. June 21st was πMND Awareness Dayπ§‘ and we shared the story of our colleague, Jordan, whose resilience, determination and positivity continue to inspire us every day. Many of our customers across the UK will know Jordan. For years, he was a familiar face on the road, visiting customer sites, carrying out service work and calibrations, responding to breakdowns and helping to find practical solutions whenever challenges arose. His professionalism, knowledge and willingness to help made him a valued member of both the JTS team and the wider community we serve. When Jordan was diagnosed with Motor Neurone Disease (MND), life changed significantly. Together, we adapted his role so he could continue contributing in a way that worked for him. Today, Jordan works remotely, providing technical support to our field service engineers and contributing to our health and safety processes through risk assessments. While his role has changed, his expertise and experience remain just as valuable as ever. Alongside work, Jordan attends Sandville Self Help Foundation where he takes part in therapies, including hydrotherapy and physiotherapy, that help make day-to-day life more manageable for him which he says he is really enjoying and it’s having a positive impact. Jordan's journey is a reminder that, with the right support, understanding and flexibility, people can continue to make a meaningful impact. It's about recognising the value people bring and ensuring they have the opportunity to keep doing what they do best. We are incredibly proud to have Jordan as part of the JTS team and grateful for everything he continues to do. We stand with Jordan and everyone affected by MND, together we can raise awareness, encourage understanding and support those living with this condition. ππ§‘

With EO Day on Friday 19th June, we're proud to be putting JTS on 'The UK is Owning It Map' . π The I-COM team have created this interactive map, where each pin represents a business that has chosen a different way of doing things. Every pin is a statement: we're here, we're employee-owned, and we're proud of it. We're delighted to stand alongside so many other employee-owned businesses across the UK, celebrating the power of shared ownership and the people who make it possible. At JTS, we're proud to be part of a growing movement that's putting people at the heart of business success. #EODay #EmployeeOwnership #TheUKIsOwningIt #ProudlyEmployeeOwned #JTS
