The silos are designed for outdoor storage of polymer material (polypropylene, PP) with a bulk density of 0.9 kg/dm³ and a moisture content of no more than 0.3%. They are designed to operate at ambient temperatures from −50 °C to +50 °C. FSW technology provides structural integrity, leak-tight seams and freedom from internal stresses. The installed silos passed inspection at the customer’s site and have been commissioned.
