SINGLE-CIRCUIT SYSTEM WITHOUT TANK

The cooling medium circuit is designed as a single-circuit system without tank. The pump conveys the
cooling medium inside the circuit through the evaporator and through the consumer.
The cooling medium in cooled inside the evaporator. The circuit consists of the following components:
pump of horizontal or vertical design,

piping system consisting of copper or plastic pipes with manometer and probe connection for the

