Conversions Division Case Studies

Case Studies: Engineering Process Enclosures S Jones Conversions division is the UK’s leading container conversions specialist. We design and manufacture bespoke containers, enclosures and plant rooms for the safe and compliant housing of engineering processes, equipment and machinery.

For decades, we have specialised in providing clients with Contained Space Solutions®. This brochure contains a small selection of the thousands of container conversion projects we've completed for some of the most reputable engineering companies in the UK.

State of The Art Lithium-ion Battery Storage for Coventry University In 2019, Coventry University collaborated with global engineering specialist FEV Group to develop a stateof-the-art low carbon technology centre.

What Coventry University Had To Say: “It has been over five years since I worked with S Jones on the very first bespoke container for battery storage. Having the ability to store our new and used Lithiumion batteries safely plays a key part in the

The S Jones Lithium Battery Storage Solution After working with Coventry University on the specification, we used our CAD (Computer Aided Design) expertise to generate an accurate visual representation of the shipping container that would ensure full functionality prior to build.

Building from this design, we then fabricated the battery store in our purpose built workshop before

operations of our research centre. I am very pleased to see how the design of the container has evolved over the years to include many new features to meet the latest safety requirements, making it the industry’s best practice for battery storage.

Thank you so much for doing a great job!”

Custom-Built Plant Rooms for Global Water Treatment Leader Culligan, a leading water treatment supplier, is committed to delivering state-of-the-art products and water solutions while minimising the impact on the environment. The company has been working to provide better water for their customers in their working environments around the world for over 80 years.

The Challenge and Solution Culligan contacted us with a requirement for secure temperature controlled enclosures for their equipment to be housed in.

What Culligan Had To Say: “We find that our customers are requiring a ‘Plug and Play’ solution for their water treatment systems more and more. Culligan has the expertise to provide these solutions. With our inhouse team we have the capabilities to provide a complete turn-key solution to suit the customer’s requirements.

We wanted to use a professional company for our container conversion project, which is why we partnered with S Jones Conversions. They demonstrated early on in the project that they

Housing Cummins’ Energy Regeneration Processes In Bespoke Containers As part of their sustainability efforts, Cummins wanted to house equipment for a ground-breaking solution that would recover electricity from their diesel engine generator test process.

Involving the stacking of two containers, the project provided a welcome challenge for our talented team, seeing us design and manufacture the containers entirely in-house.

The two bespoke 40ft high cube containers allow Cummins to safely and compliantly house the equipment necessary to sell back energy to the national grid at a time when sustainability has never been higher on the national agenda.

What Cummins Had To Say: “S Jones were adaptive and flexible throughout the engineering phase, especially considering the effects of Covid-19 and the lockdown at the time.”

“S Jones’ designers were engaging and contributed creative ideas to help us achieve this challenging project.”

The Solution Utilising a wealth of experience, S Jones delivered a number of innovative and vital elements to this revolutionary project, including: Agile Digital Visualisation: S Jones created a detailed 3D CAD design model of the container which imported the relevant Siemens technology needed to power the plant.

This visualisation was used in Siemens virtual reality simulator enabling S Jones to guide the customer around the art of the possible, enabling quicker decision making and stakeholder engagement for the customer.

Risk Mitigation: S Jones installed sound attenuated linings and a fire alarm system to ensure compliance with health and safety standards, alongside corporate mitigation measures, throughout the operational lifespan of the container plant.

Expert Engineering Knowledge: One of the biggest challenges of the container was creating enough space to accommodate the sheer scale of the technology required to run the plant efficiently.

We provided complex structural modifications such as a galvanized steel roof platform and a sub floor stiffening structure to ensure our client had peace of mind that the plant would run safely and effectively.

In-house Proofing and Fabrication: S Jones provides end-to-end customer experience, from initial concepts through to the final design sign off.

We completed the fabrication of the container in our workshop in the West Midlands, offering Siemens the opportunity to see their vision turned into a reality, every step of the way.

What Siemens Had To Say: “S Jones provided a flexible approach to this prototype design, allowing multiple design changes to be included throughout the build.

This allowed our engineers to fully develop this world-first concept. The results are a high quality solution, fully meeting our requirements”

measures for environmental monitoring and control within the containers were also necessary to provide effective heating and cooling for the equipment, alongside the PQF, contained Variable Speed Drives and other significant heat-generating equipment.

Safely On Site, On Schedule To assist with the turn-key solution, the container had to be equipped with a certified Fire Alarm system (interconnected with the MCC) to effectively cut the power by tripping the Mains and Generator Air Circuit Breakers in the event of an alarm. Together with the alarm system, general domestic services were built into the container customisation and connected back to the MCC. Following the build and witness-testing by the clients, the MCCs were installed into the containers at CEMA's factory, re-built and re-tested prior to delivery.

Specialist lifting and transport equipment was employed to enable the completed units, weighing

Thinking Outside of The Box The original concept of providing high-volume forcedair ventilation of the container was dismissed as being too noisy and not cost-effective. As a result, we modelled the worst-case heat-gain scenario, taking into account insulation values of the custom container build (including the solar gain relative to the geographical location and external colour of the container) to identify the most economic airconditioning solution for the buildings.

Field cabling access to the MCC was developed with an innovative approach adopted for cable glanding.

Given the height restrictions within the container cable, glanding space within the MCC had become compromised. To counter this, we applied our out-ofthe-box thinking by relocating the gland plates to the underneath of the containers, which were to be suspended above ground to provide cabling access from below.

What CEMA Had To Say: “S Jones presented themselves and their capability far in excess of their competitors.

Their understanding of the client requirements and the attention to detail was paramount to the success of the project.

Working directly with Andrew and Les meant we had direct access for timely and knowledgeable decisions and guidance. We would highly recommend S Jones for all partners on future schemes.”

Client Equipment Integration Highlighted below are many of the elements we change to provide enclosures and work spaces that clients need: 3D CAD design – A modified container with a lot of specialist equipment involved can be a very crowded space. Not only is there the equipment for controlling the internal environment, but also the client’s own equipment together with adequate access requirements. To ensure that everything fits appropriately, and to greatly assist in the design process, we have used 3D CAD for many years. This is an area of our specific expertise and has also been used to seamlessly integrate with client's own VR suite facilities.
