Rising To The Challenge

September 7, 2022

The evolving test requirements for Electric Vehicle battery packs means test specifications are constantly being pushed to new boundaries. JTS has risen to these challenges with our range of containerised test chambers. With extensive experience in the design and build of reliable high-performance bespoke environmental test chambers we provide solutions to large multi-national companies, both here in the UK and overseas.

JTS has an ethos of working closely with customers and this proved invaluable with a recent design brief for a containerised test facility. The build specification required a temperature controlled test chamber, an office area for engineers and an area for refrigeration plant and the customer’s chiller.

Our design utilises a 30ft tunnel container with an additional personnel door for access to the office. A side window introduces natural light to the office and louvre panels facilitate a flow of fresh air through the plant area.


The 2m x 4m test area provides a controlled environment over a range of +20°C to +40°C, with capacity for test loads dissipating up to 10kw. The ceiling mounted air handling unit is fitted with a fan speed controller, allowing the customer to control the airflow within the chamber. A bunded anti-slip floor enables safe containment of any spilt test fluids, up to a depth of 100mm. Access for loading is via double doors at one end of the container and a fire rated personnel door gives access from the office.  An array of IP65 rated 230V and 400v sockets are fitted either side of the test area for customer use.

For safety a 60 minute fire rated bulkhead is incorporated between the chamber and the 2m x 3.5m office area. Laminated insulation panels line this area and an aluminium anti-slip floor gives a clean bright working environment. Further enhancements include air conditioning, continual fresh air purge and emergency LED lighting.


The plant room at the end of the container houses a Bitzer Ecolite air cooled condensing unit and the cooling plant for the air conditioning system. Free space is also allocated in this area for the customer’s test load chiller and their Statx fire suppression system.

There will never be one design that fits all scenarios of testing. From containers to walk in rooms, floor standing to bench mounted, our wealth of experience and continuous product development enables JTS to engineer bespoke solutions.

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 πŸ’™MND Awareness Day🧑 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. πŸ’™πŸ§‘

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 πŸ‘
