Background

Selig Group is an industry-leader in innovative sealing and venting solutions that are utilised in rigid containers for markets including FMCG, healthcare and chemical. They operate globally across six sites and serve over 10,000 brands.

Selig Group’s Slough facility manufactures ‘induction liners’ which are foil-based seals located beneath the lids of bottles or jars, providing an airtight and tamper-evident cap. Their production involves a lamination process, and the relocation of this equipment from another Selig site to the Slough facility created the requirement for a Regenerative Thermal Oxidiser (RTO) to comply with environmental legislation.
As there was never previously a requirement at this site, the installation of an RTO was a first-time introduction, and Selig needed expert guidance on how the technology could be implemented.
Challenges
In the initial assessment, Spooner sought to uncover all the key details to advise Selig on the best solution going forward.
“We had no prior knowledge of RTOs in the UK and were seeking support which led us to Spooner. Lois Scott and Jim Colston visited our site for a feasibility assessment and the primary deciding factor between choosing Spooner and a competitor was the relationship built in the initial stage and the approachability of the team at Spooner. Their experts taught us how the RTO operates, what the oxidiser could offer us and, overall, they had a significant knowledge base.”

Solution

On completion of the assessment, Spooner’s Applications Engineering team identified that the best solution was a 30,000Nm³/h capacity RTO with an air-to-air heat exchanger system to deliver pre-heated air back to the laminating process, reducing energy consumption.
As the project progressed, due to a change of the RTO equipment intended position, Spooner identified that an air-to-water heat exchanger would be more suitable rather than the original air-to-air system. The project scheme was adapted accordingly, and the final solution designed to ensure the most efficient system would be delivered.
Result
The Spooner scope included full installation and commissioning of the system, with integration with the laminating process equipment key. The site aspects of the project, with the strong collaboration and partnership of Selig, progressed smoothly and production performed well from start-up.
“The installation delivered by Spooner was excellent and very methodical. They were careful, taking into consideration the high degree of health and safety challenges that were presented in the RTO installation. We couldn’t fault it, and we actually had a lot of compliments from the site team and the principal contractor who was overseeing the wider construction changes.”

The final RTO capacity and heat exchanger solution meant Selig would easily be able to meet current regulations, operating efficiently with current production levels, and with the capacity available in the future should they expand production and integrate further production lines.
“Spooner presented exceptional technical knowledge that was integral to the RTO installation, which for Selig Group was business critical. We had confidence in the team’s ability to deliver and were impressed with the questions asked throughout the assessment. The team at Spooner were very responsive, communicating with the engineers on key updates, and aligning with the principal contractor’s wider factory changes. Overall, it has been a pleasure working with Spooner.”
