The site post pasteurises all its feed stock to meet PAS100 requirements. The feed stock then needs to be cooled around 47-50°C before it is pumped into the digesters.
The client was using multiple air blast chillers and compressor chiller units to try and meet the cooling demand on site, however even with these multiple units they were unable to cool the feedstock effectively and the multiple units had a large electrical consumption adding large costs to the process.
We were asked to deliver a system that could cool all of the feedstock with a future uplift of 30% and with a lower electrical consumption.
