Condenserors are used for condensation of vapours and cooling of liquids. Condensers are made by fusing number of parallel coils in a glass shell. Coils are made in different diameters using tubes of different bores.
The average co-efficient of heat transfer in coil condenser is considered as :-
Water main should be connected with flexible hose.
Ensure no freezing of water remaining in the coils.
Condensers should be mounted verically only.
Condensers can be mounted in series to provide larger surface area.
METHODS OF USE
Vapours from Bottom This method is simple to install over a reactor. However, this results in condensate returning substantially at its condensing temperature. In this method care must be taken that condensate is not excessive that it can lead to "logging" the coils and create back pressure in the system. Generally a reflux divider is used below the condenser to take out the distillate.
Vapours from Top This method produce a cool condensate using the entire cooling surface area. this method should be used where the condensate can lead to "logging" of coils.
