The concept of the unpressurised, enclosed coolant circuit was selected for the cooling of the special synthetic heat transfer<br />
fluid. The liquid-air cooler with an expansion vessel, which handles the cooling of the heat transfer fluid, is the centre-piece<br />
of the heat exchanger unit. The axial fan provides the required air flow and the maintenance-free, high-temperature resistant<br />
centrifugal pump circulates the heat transfer fluid.<br />
