A condenser tube is nothing more than a glass cylinder that is created for the sole purpose of rapidly cooling liquids that are held within a separate container. There are various configurations of condenser tubes, but they all have similar traits: two external glass joints that connect to other devices, a centralized glass bulb that allows for heat dissipation and a small interior glass tube that passes either water or air through the center of the condenser. This process allows extremely hot liquids and gasses the chance to be drawn from the heat source and cooled, and once this takes place, they are added back to their original storage area. Not only does a condenser tube extend the usage of liquids and gasses found in machinery, it also makes them function at a more efficient rate.
It might at first appear questionable as to why a condenser tube would be necessary at all. The answer is nowhere as complex or scientific as some would think; a condenser tube is primarily implemented to reduce waste. For example, in the boiling of water on a stove for cooking purposes, when the cooking instrument is cool, the water level is easy to maintain at a desired height within the pot, but as the temperature increases, some of the water is turned to steam and evaporates. If a glass lid were to be placed on the cookware and a condenser tube was attached, that steam would be drawn from the pot, cooled back to liquid form and then added back to the rest of the water. This example may not seem practical, but businesses around the world use condenser tubes because the liquid being heated can be extremely expensive, and this process eliminates much of the natural waste by controlling evaporation levels.
The primary condenser tube material is glass, so maintenance often can be an arduous task that requires frequent inspection and cleaning. A proper condenser tube cleaning system would flush the condenser tubes while they are not in use to remove any buildup of trace metals or other deposits, and when completed correctly, the condensing tube will have an extended life expectancy of several years. Maintenance normally is conducted quarterly on machines that do not deal with excess solids during the heating process, and it is done more frequently for those that do.
The presence of condenser tubes has become much more common in businesses because of the financial savings involved after their proper installation. They are especially popular in machines that deal with elements that are not easily replaceable. This is why they can be found on everything from inexpensive laboratory equipment to nuclear reactors.
