|We were asked to design, supply and install 2 No. Flue systems to suit the 2off new Giesen coffee roasters.
The larger Giesen W30A coffee roaster required two flues – one for the roasting and one for the cooling. With close consideration to the specification, it was decided that due to the high temperature of the roasting exhaust we would opt for a 200mm twin wall 316L stainless steel flue system. The cooling bin has low temperatures, therefore we opted for a 200mm 316L stainless steel single wall flue system.
The smaller Giesen WPG1 only required one flue for the roasting, which can reach temperatures of 80°C. Due to these temperatures and its low exhaust level, we opted to go with 80mm twin wall 316L stainless steel flue to ensure the touch temperature was kept to a minimum.
The overall flue had to be installed in coordination with the existing coffee roasting schedule.
