Duct-IN Ltd was formed in 2020, firstly to support Air Conditioning Engineers with a fast and reliable service for supply and return air plenums. We found that engineers did not have the time to search through data books to provide dimensions of ducted units and then arrange manufacturing. Instead, Duct-IN worked in the background to collate the data from the leading air conditioning manufacturers in the UK.
