Production Reliability and Continuity

Stoats are leading producers of oat based food products including porridge oat bars, porridge pots and traybakes.

Key objectives

Ensure new compressors and associated machinery are reliable to cope with an increase in demand and are compliant with air purity regulations.

  • Oil Free Compliant with ISO 22000
  • Equipment Reliability
  • Future-proofed System


The old air compressors and associated equipment were deemed unreliable for an increase in demand due to a new product line being introduced. In addition, there was no bypass meaning servicing was an issue as there was no alternative but to stop production while any servicing was being carried out and with the new product consistent uptime was necessary. 


We carried out a site survey with data collected to understand the current air usage. Due to the nature of the product being manufactured oil-free air was essential as even the smallest drop of oil risks contamination and severe consequences in food manufacturing. We installed a complete compressed air solution consisting of two oil-free screw compressor that meets the class zero standard and a refrigeration dryer ensuring highly effective removal of water vapour from the compressed air maintaining the quality. This new solution meant production no longer needed to rely on one unit and it also future-proofs the system for future growth in production. We also modified the pipework to give a bypass which will ensure production uptime when any servicing is being carried out.


We are very happy with the compressed air solution installed by CPA, they absolutely understood our objectives.  As a growing business, continuity in our production is of the utmost importance and it is all down to the reliability of the equipment
