The Difference Between Closed and Open Circuit Cooling
2021 3 18 More about Closed Circuit Cooling Towers A closed circuit cooling tower or dry cooling tower involves no contact between the air and the fluid being cooled This tower has two separate fluid circuits one in which the fluid is recirculated on the outside of the second circuit which is a bundle of tubes through which the hot water is flowing.

Cooling Tower Pumping and Piping
2013 3 11 The open or tower circuit is different from the closed loop circuit The difference is that all static heads are not cancellable In the open piping circuit the pump must raise fluid from a low reference level to a higher level this requires pump work and open statics becomes an important consideration for pump selection Figure 2

Autotransformer Starting Open and Closed Transition
Open transition simply means that there is a brief period of time when the motor is dis connected from power when the start contactor opens and the run contactor closes The circuit shown in Figures 38 2 and 38 3 are examples of an open transition starter Closed transition starting is generally used on starters size 6 and larger.
