Abstract
An antifreeze system for a pipework, the antifreeze system comprising a framework configured to be fixed to the pipework, and at least one thermally insulating sleeve maintained around the pipework by the framework. Each sleeve is configured so that a space is produced between the sleeve and the pipework. The framework has an inlet and an outlet which are configured to produce a fluid communication between the outer side of the antifreeze system and the space. The inlet is fluidly connected to a source of hot air. Such an antifreeze system thus enables a flow of hot air around the pipework which thus prevents the liquid which flows therein from freezing.
