When it comes to removing contaminants from your industrial air compressor system, there are two primary types of dryers that are used: desiccant dryers and refrigerated dryers. Each one of these different types of dryers has its own practical purpose, and each one is effective at removing moisture, condensates, and contaminants from the air.
Contaminants build up in the air compressor system when air is heated through the compressor machine before being pushed out in the form of energy. This heat allows moisture, such as water vapor, to begin building up in the system. On top of the moisture, liquid and non-liquid contaminants, such as oil and dust, will also build up. Removing these condensates is a vital step in the industrial air compressor maintenance process.
A refrigerated dryer is the first type of dryer that can be used. This device runs on the simple premise of condensation. By cooling the air as it passes through the valves in the system, moisture droplets that contain water vapor, dust, oil, and other contaminants will be drained into a large tank or an external unit. These dryers come in two forms, cycling and non-cycling, and the appropriate dryer to use for your system will depend on its specs and your individual requirements.
A desiccant dryer is the alternative to a refrigerated dryer, although desiccant dryers have been around for much longer. In this system, the compressed air is not cooled, but instead passes through chambers of disiccants which are moisture removing packs that absorb water vapor and contaminents in the water vapor. These packs can be easily disposed and replaced with routine maintenance, and are a great way to keep your industrial air compressor running in top shape.
When it comes to saving energy, desiccant dryers are always a smart choice because they do not use much additional power compared to the refrigerated dryers. However, newer and better refrigerated dryers are becoming available that use heat exchangers to cool the air to optimal levels and not overcompensate for the air outside the system. This allows the energy costs of a refrigerated dryer to remain low, while also keeping maintenance and repair costs down.
A final possible solution to saving energy while still removing contaminents properly and throuroughly is to use a combination of both a desiccant and refrigerated dryer. The desiccant dryer will remove any moisture from the system in the intial stages of compression, while a low-power refrigerated dryer is used to finish the job down the line. By utilizing this system, not only do you save money on the maintenance of both dryers, but the low power refrigerated dryer will keep energy costs down, saving you and your business a great deal of money.
