This week we want to talk to you about an ATEX rated diesel engine cooling system for offshore oil rigs in the North Sea.
Our partner Broadland Radiators was approached by their client who was looking for a cooling system similar to those previously supplied but with some additional requirements. The new system needed to:
Broadland’s engineers considered the different parameters of the system to be supplied and created a design that worked to the new application requirements. The engineers also considered the transportation of the radiators as this is something that could cause significant damage to the system if not correctly handled.
The offshore facility needed a new diesel engine cooling system, similar to their current solution but to meet more challenging conditions in an ATEX environment whilst also overhauling transport which required a newly designed lifting frame.
To meet these requirements, Broadland Radiators’ solution included:
A brand-new radiator system was designed that incorporated a TCH mechanically sealed centrifugal pump for re-circulation of the cooling fluid. To prevent overheating, the cooling fluid is constantly re-circulated within the engine. This particular pump is an extremely flexible solution, capable of handling heavy duties.
The new cooling system designed by Broadland Radiators utilises our TCH centrifugal pump (seen at the bottom)
Manufactured in stainless steel, with a stainless-steel bearing bracket, this pump is capable of operating in an extremely wide range of outdoor temperatures whilst offering the corrosion resistance essential for offshore facilities. The bespoke system was manufactured to keep a selection of large, high-powered motors from overheating and as a result, CDR supplied a pump motor that was also capable of withstanding such a low ambient temperature.
The result is a brand-new cooling system that is ATEX compliant, ISO 9001 and 14001 compliant all within a DNV compliant frame. Safety is of paramount importance on oil rigs the length and breadth of the North Sea and we are really proud to have teamed up with a progressive company to bring a solution that really works.
As a company, we work closely with OEMs so that they can provide the best solution possible to their own customers. If you would like to incorporate any CDR Pumps’ fluid handling solutions into your own designs, please do get in touch.
We are delighted to announce that CDR Pumps has been shortlisted as a finalist for the Chemicals Northwest Supplier to the Chemical Industry Award 2026.
Being shortlisted is a fantastic recognition of the work our team does every day to support the UK chemical industry with innovative, reliable and safety-focused pumping solutions….
A long-term customer, who operates within the chemical manufacturing industry, approached us because they needed to modernise and improve control over their tanker unloading processes. Their existing systems operated by either using the “blowing method” or relying on pumps mounted on the tankers and weren’t particularly reliable, consistent, or safe, especially when it comes to handling aggressive chemicals such as 96% Sulphuric Acid and 50% Hydrogen Peroxide.
Chemical pumps improve the performance of your fume scrubbers!
It’s a bold statement, but true. Industrial ventilation plays a key role in workplace safety and regulatory compliance in manufacturing plants. Industries like chemical processing, pharmaceutical manufacturing, and metalworking rely on robust (and reliable) ventilation systems to remove harmful fumes, particulates,…
What You Need to Know
Moving thousands of litres of valuable spirits through various production stages each day, pumps are at the core of alcohol manufacturing and distilleries. A single pump failure can completely stop production, compromise product quality, and result in significant financial losses for UK distillery operations.
