In fact, DPL’s long history of servicing this sector has seen us develop effective business partnerships with both brewers and contracting engineers in the supply of processing equipment for:

From the supply of a single valve to the manufacture of CIP systems and specially designed plant, Dairy Pipe Lines brings a wealth of experience and has developed a specialist approach to determining solutions to all sorts of brewing problems.

The increased competition with other drinks such as alcho-pops, coupled with ever rising production costs, have resulted in an evolution in brewing methods and we at DPL are proud to have been part of this change.

Throughout the brewing process - from the brew house and yeast handling, mashing and sparging, air removal, CIP, clarification systems and product recovery to dosing - DPL offers a range of quality, high performance valves and valve systems backed by technical data and industry knowledge which is second to none. Our areas of expertise also include fabrication and specialist pipe line products.

DPL’s future in the brewing industry will be driven by the development of new products, in close consultation with customers old and new, and the continuation of a long and proud tradition based on quality and service.

A major manufacturer of data centre cooling units had received a request from one of its customers to supply its coolant distribution units (CDUs) with stainless steel pipework instead of the traditional brass or copper.


So began a four-year journey where SFL assisted its client in the design, manufacture and assembly of the world’s first stainless steel coolant distribution unit.
SFL’s initial input into the project was to help in the design of the stainless steel pipework that would be installed in the CDU. Working as an extension of its client’s engineering team, SFL helped create a series of 2D CAD drawings and 3D models.

One of the challenges SFL faced was how to fit the new pipework into the existing space, given that stainless steel isn’t as malleable as brass or copper. Through its meticulous and methodical approach, the team successfully arrived at the first version of the CDU pipework that fitted perfectly into the same footprint.
SFL’s next task was to manufacture the set of pipework for the prototype unit, ensuring the kit was manufactured to the highest possible standard. SFL then assisted in the assembly and successful fitting of the pipework into the initial unit.

The unit was then shipped off to a major trade exhibition in the USA to demonstrate the first stainless steel CDU for high performance computing and enterprise data centres. Following the initial blueprint of the prototype design, SFL helped its client fix a number of bugs and resolve a few issues in order to create the optimum design. Once everyone was happy with the final result, the team was then in a position to embark on full-scale manufacture.


Switching from brass to stainless steel offers a marked increase in quality and purity that had never been available in this market before. For example, stainless steel pipework in CDUs means improved performance, as the coolant fluid flows more efficiently through stainless steel pipes, compared to brass or copper. Another advantage is lower maintenance costs as the coolant fluid doesn’t need to be filtered or changed as frequently. A further benefit is that stainless steel is resistant to both corrosion and leaks.


After the unit was unveiled at the exhibition, orders flowed in from around the world and SFL was asked to manufacture 50 kits, destined for end customers located in Australia, Japan and the United States.

Andrew Sharp, Manufacturing Manager at SFL and part of the team who worked on the CDU project, said: “As well as becoming part of our client’s design engineering team, working on the design concepts, we also helped with the ongoing manufacture and assembly of the pipework units. We even became part of their purchasing department, buying the various components we needed in order to build our stainless steel kits. This puts us in a strong position to help other manufacturers of large data centre cooling systems who are looking to benefit from the advantages of stainless steel pipework in their units.”


  • Design acumen: measured approach, coupled with in-depth experience, when helping with the design stage of the project.

  • Prototype skill: ensured the first pipework kit was manufactured to the highest possible standard for the exhibition and was also fit for purpose.

  • Problem solvers and trouble shooters: worked alongside the client to help with all the changes required to make the unit operate at optimum efficiency and work rate.

  • Full scale manufacturing ability: set up a bespoke manufacturing cell to ensure manufacture of two kits each month, to supply market demand.

  • Dedicated account manager: daily one-to-one contact with the client, working across time zones, to provide a high level of personal service, ensuring all project issues were overcome and all deadlines met.

  • Industry knowledge: extensive understanding of HVAC/data centre cooling requirements and deadlines, to supply the growing market in hygienic stainless steel HVAC/data centre cooling systems.
