The Jumbo Curing Oven Type COT is designed to perform post-treatment on processed jumbos. The oven is usually installed nearby the maker area to permit a quick passage from the coating plant winder to the oven inlet. Oven sizes are designed and realized based on customer requests. Based on these specifications, the jumbo curing oven size could vary from a few meters long up to practically any length. Biko realizes all the mechanical parts involved in the jumbo transportation and manipulation and installs the whole oven: transportation, heat distribution and exchanging, isolation, electrical components and software.
