Worldwide locations A leading waste-to-product company in the Aylesbury area recently encountered a problem after some site equipment broke down unexpectedly. One of their anaerobic digestion plants stopped functioning at full capacity and consequently began processing waste at 50°C – too hot for the bacteria to produce gas.
The company needed to reduce the temperature of waste to no more than 40°C, with approximately 90,000 litres of waste processed on a typical day. They then contacted Andrews Chillers to provide a solution that could act as a stand-in until the faulty permanent unit was replaced.
Our swift reaction and local presence meant we were able to conduct a thorough site survey within 24 hours of receiving the initial call. This allowed a regional technician and the customer to liaise directly and make a swift decision about which size chiller would best suit their needs. We then delivered a 375kW chiller along with a generator and fuel tank to help bring temperatures down to the desired level.
The chiller was installed by an Andrews engineer shortly after, reducing the temperature of processed waste once fully operational. The environmental waste company was then able to produce gas again – feeding their turbine and enabling the production of electricity from the digestion plant to continue as it had before.
