Electrolux Laundry Systems is the world leader in manufacturing professional laundry equipment. The machines are used in the hotel sector, elderly care, in multifamily houses, laundry bars, and in commercial and institutional laundries. If there is oil or grease left in the clothes after washing may the heat from the dryer cause a chemical reaction. This reaction may, under certain circumstances cause a fire inside the drum. Competitors to Electrolux has developed its own systems that extinguishes fire inside a tumble dryer and customers have expressed desire to purchase a fire-extinguishing system. Therefore, the project team received the task by Electrolux to develop a fire-extinguishing system that extinguishes a fire in a tumble dryer. The purpose of the project has been to develop a system that both detects and responds to fire in an industrial tumble dryer to meet the competitors and to satisfy customers' requirements. The goal was to develop a fire-extinguishing system for Electrolux Laundry Systems and develop a fully functioning prototype. The project began with information searches on a variety of methods to both detect and extinguish a fire. Subsequently, a number of different methods were used to develop a final solution and make a prototype. The result of the project is a fire-extinguishing system that extinguishes a fire inside a dryer. The system is entirely mechanical and uses water to extinguish the fire. In addition, the system is not visible from the outside. The system that the team developed well meets all the requirements and preferences who where set out in the beginning of the project. The purpose and goal also correspond well with what was stated at the beginning of the project.
