Coil Type Glass Heat Exchanger

Coil type heat exchanger is mainly used as condenser or cooler. It can, however, be used for heat transfer between liquids & gases in general. It has the coil battery welded to the jacket making a one piece unit. The maximum allowable pressure in the coils is 2.7 bar gauge.
PRECAUTIONS TO USE CONDENSER ARE AS FOLLOWS:
When connection coil-type condensers to the coolant supply, adequate flexible hose should be used to ensure that stresses are not transmitted to the glass. sers to the coolant supply, adequate flexible hose should be used to ensure that stresses are not transmitted to the glass.
Condenser should never be operated with steam in the coils. They should always be used with an adequate flow of coolant through the coils and care should be taken to ensure that the coolant does not become heated to boiling point.
Coolant control valves should always be turned on and off slowly, particularly when air is present in the line. Coolant should be allowed to drain freely to a point as close as practicable to the heat exchanger.
Care should be taken in arranging the coolant supply in order to avoid water hammer A uniform, continuous supply of coolants should be ensured.
If a condenser is out of service for any length of time, it is advisable to drain the coils, especially in winter when suitable precautions should be taken to prevent freezing of any water remaining after draining.
Brine or other coolants in closed circuit can be used as coolant provided the suitable precautions against water hammer are taken.
Condensers can be mounted in series to provide larger surface area. Condensers should be mounted vertically only.
The maximum pressure in the coil is 2.7 bar. The maximum differential pressure across the coils 2.7 bar.
