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.
At JTS, Health and Safety is a responsibility shared by everyone across our employee owned business here in Wales. As manufacturers of environmental test chambers, we regularly handle large and heavy equipment, making safe manual handling practices and properly trained forklift personnel an essential part of our day to day operations. National Forklift Safety Day is an important reminder of the role trained operators play in keeping our workplace safe, efficient, and compliant - helping reduce risk, prevent injury, and ensure materials are moved safely and correctly. A huge thank you to our forklift drivers and wider team for continuing to put safety first every day. Because good safety culture protects people, products and productivity. We’re also pleased to share that two of our workshop engineers are currently completing forklift operator training this week, further expanding our team of qualified forklift drivers 👍
Taking ACTION for Mental Health. At JTS, we believe that building high-quality environmental test chambers starts with something even more important—supporting the people behind them. As an employee-owned company, our people are at the heart of everything we do. This Mental Health Awareness Week (11–18 May), we’re embracing this year’s theme: ACTION. For us, ACTION means: Checking in with colleagues—not just about work, but how they’re really doing Creating a culture where it’s okay to talk openly about mental health and how we are feeling. Taking breaks, setting boundaries, and supporting wellbeing every day Encouraging each other to reach out—because no one should feel alone. Small actions can make a big difference. Together, we can create a workplace where everyone feels supported, valued, and heard. Let’s take ACTION—this week and every week. #MentalHealthAwarenessWeek #MentalHealthMatters #TakeAction #EmployeeOwned #WorkplaceWellbeing #MHAW26 #MentalHealthFirstAid
