Compressed Air Dryer Troubleshooting Guide – A Systems Approach
I’m asked quite often to troubleshoot compressed air dryers when they’re not working. It’s not just Van Air Systems dryers—I get calls on every make and model imaginable, from Atlas Copco, Parker, and Schmidt; from regenerative to desiccant dryers. Air dryer dew point problems can include: Wet air downstream of…
How Long Does Desiccant Last?
How long desiccant last depends on several factors, including the type of dryer, application, and the level of maintenance provided. For instance, with proper maintenance of pre-filters, activated alumina desiccant can last up to 5 years in heatless dryers, but only 2 to 3 years in heat-regenerated dryers. (It’s important…
What is an Aftercooler?
Definition An aftercooler is a device used to cool and compress hot air that comes out of the compressor. Thus, aftercoolers are essential to ensure that the compressed air is cooled before it enters an engine’s cylinders. Why? When air is compressed, it heats up due to the pressure created…
Oil and Gas Wellhead Sites use Compressed Air to Reduce Emissions
Traditionally, oil and gas operators used methane driven devices because of the abundance of natural gas available for their valves and the operation of safety devices. However, when those instrumentation actuates they release methane emissions into the atmosphere. With more growing concern on green energy and emission reduction more and…
What is a Compressed Air Dryer?
Definition A compressed air dryer is a device for removing water vapor from an air system. That is, an air dryer’s main function is not removing liquid water, which is the role of a compressed air moisture separator and coalescing filter. Compressed Air Dryer vs. Moisture Separators Many owners of…
Why 4UF Deliquescent Desiccant should not be used in place of 10BF Desiccant.
With the summer ending and cooler months upon us, it’s that time those that use our 10BF for the dehydration of Natural Gas may think to start refilling their deliquescent dryers with desiccant. 10BF is the most effective deliquescent desiccant from Van Air Systems. Formulated primarily for the dehydration of…
