Abstract: The disclosure relates to a paint system for coating components with a coating medium, in particular a painting system for painting motor vehicle bodywork components with a paint, comprising at least one pneumatic pump for circulating paint in the system. The pneumatic pump includes a feed air connection for feeding in a feed air stream for mechanically powering the pump and an exhaust air connection for conducting away a depressurised, cold exhaust air stream. The cold exhaust stream passing through a first heat exchanger where the heat exchanger cools a medium in a cooling circuit and the medium cools a heat-sensitive component. The heat sensitive component can be the paint circulation lines or a protective housing for the robot.
