Essentra Components manufacture parts from packaging and fluid handling to moulded plastics and hardware. They operate over 100 injection moulding machines at their large site in Oxfordshire.

Their machines utilise Chillers and V Bank Airblast Coolers to provide cooling to the tools at 14°C and to hydraulic oil at 20°C. Minimising downtime is crucial to their production, so they need a maintenance partner that they can rely on to maintain and optimise their chilled water system and equipment.

The situation

The manufacturing site required a reliable and supportive partnership with a reputable provider of high-standard technical support, maintenance, and servicing.

The use of mixed metals in the internal factory pipework had caused corrosion, which led to the poor quality of water running through the system, damaging the pipework and causing leaks.

If closed-loop systems or the water used within them are poorly maintained or left untreated it can lead to problems that will affect energy usage, cost, asset performance, and reliability. Specifically, these problems include corrosion, fouling, biofouling, and scaling to a lesser extent unless there is significant water loss requiring additional make-up water.

These issues were resolved in the recent past by adapting their cooling water system from a closed-circuit pressurised system to an open tank system – making it easy to monitor the quality
of the water and add treatment as needed.

The solution

We are providing the site with technical support, maintenance and regular servicing of the equipment. This includes cleaning and ushing the dual filter arrangement to ensure clean and treated water is provided – protecting the system components and minimising the risk of downtime.

The Client –

UK Industrial Gas Manufacturer


The Challenge –

System Upgrade, Within Restricted Footprint


The Solution –

Built To Order Air Blast Solution

Our client specialises in the manufacture of industrial gases which are used across several sectors including food & beverage, medical and petrochemical, to name just a few. As well as more widely known gases such as oxygen, nitrogen and helium, some speciality gases are manufactured for specific processes.

Aqua were tasked with upgrading the cooling to the compression system used in the gas manufacturing process. As production has increased over recent years, our customer was keen to replace their existing dated equipment with new whilst increasing the system’s cooling capacity at the same time.

Limited by the footprint available, our design team worked on a specially manufactured air blast cooler design to ensure the new system would fit within the existing space. Along with the cooler, sits pumps, pressurisation set, expansion and header tanks. Using 3D imagery, our designers ensured all the equipment would fit into the restricted footprint.

The system is sat on a skid, with a control system bespoke to the client’s specifications. The skid design enabled the entire system to be delivered to site and connected, keeping installation work and disruption to production at a minimum.

The bespoke 490kW capacity air blast cooler, incorporates EC fans and the pumps have inverter drives, maximising overall energy efficiency. It’s anticipated that energy saving will be over 50% compared to the legacy cooler that was in situ.

The full solution included:

  • Custom skid design
  • Bespoke equipment manufacture
  • Air blast cooler, pumps, pressurisation set and tanks,
  • Bespoke control system

In addition, because the air blast cooler is in a coastal environment, final specification included marine paint and coated fins to eliminate any risk of corrosion.
