Is an adsorption dryer necessary for screw air compressors?
Thread Content
The company needs to purchase a screw air compressor, and now the manufacturer is asking us whether we want to include a \"microheat regeneration adsorption dryer\" as well. I would like to ask my colleagues: 1. What is the function of the so-called “micro-heat regeneration adsorption dryer”? 2. In what situations is a \"microheat regeneration adsorption dryer\" necessary?
No one answered, I’ll keep pushing! :)
Consider the gas demand on the backend; if requirements exist regarding dew point and cleanliness, an adsorption unit can be added.
Put simply, it depends on whether you have any requirements regarding the moisture content in compressed air; if not, it’s not necessary. If it is instrument air, then it is necessary. The function of an adsorption dryer is to remove moisture from compressed air (if the requirements are not high, a freeze-dryer can also be used). If cleanliness is a requirement, it is best to use an oil-free compressor
It mainly depends on the quality requirements for compressing air that you have; if these are high, then it’s necessary to use equipment that is suitable for such tasks
It mainly depends on your gas usage requirements and where it will be used; it has nothing to do with the air compressor itself
It mainly depends on the requirements of your backend system regarding air purity. If the backend equipment has no specific requirements for the air quality, then a regular refrigerated dryer will suffice; however, if there are such requirements, an adsorption dryer is necessary
It mainly depends on the requirements your backend has regarding air purity and moisture content. If these requirements are not high and the air is to be used as non-purified air, then a dryer is not necessary. However, if there are requirements for providing powered air or instrument air for control instruments, then a dryer must be installed.
1. What is the function of the so-called “microheat regeneration adsorption dryer”? The dew point temperature, in simple terms, refers to the temperature below zero at which no water condenses in compressed air. Generally, the dew point is kept at -40 degrees to protect subsequent equipment, especially precision instruments that rely on this air ； 2. In what situations is a \"microheat regeneration adsorption dryer\" necessary? Equipment that requires high performance, for use in northern regions where temperatures drop below zero in winter
