Cooling technology from goldsaat
At Goldsaat, we rely on a chemical-free and therefore more climate-friendly method for grain cooling. Our high-performance cooling units reliably protect your harvest from pests and quality loss – entirely without chemical additives.
Benefit from our proven cooling technology in the 448-DWM series – the result of decades of experience in grain cooling. Choose the right unit for your needs from our various designs and ensure a sustainable harvest.
Soundproofing system for cooling units
Our cooling units are characterized by a pleasantly low noise level, thanks to their sophisticated design and standard intake silencer. The innovative PST sound insulation ensures even quieter and more environmentally friendly operation; its unique design clearly sets Goldsaat apart from the competition.
Our cooling units
Cooling unit GK 40/448-NHD

This is how the cooling works:
Ambient air is drawn in via the cold air fan and cooled in the evaporator to the exact preselected temperature.
It is then controlled via the granosafe-/granotherm-/
granoplus technology reheats the grain. This process lowers the relative humidity and reliably prevents the grain from becoming damp – ensuring safe and loss-free storage.
