Refrigerated Air Dryers
The Refrigerant Air Dryer that we have developed and designed, stands testimonial to SPIN AQM guiding factors: remarkable attention to detail, effort to provide the best quality and engineering prowess. Our dryer stands out from others by being a core product rather than being an accessory which comes along with a compressor package. A lot of research, planning and effort has gone into the product to make it one for the long run. So when we say it’s BUILT TO LAST, we mean it.
Working Principle
Refrigerant drying cools the compressed air, whereby a large amount of the water condenses and can be separated. The compressed air is then heated so that condensation does not form on the outside of the pipe work system. The compressed air cooling takes place via a closed coolant system, where a refrigerant cooling agent is employed.
SPIN AQM’uses environment-friendly gases for this purpose. By cooling the compressed incoming air using the cooled outgoing air, energy can be saved to a maximum extent. The unique design of integrated evaporator is scaled to the exact requirement of compressed air handling. This gives greater efficiency and ultimately saves power.
Heatless Adsorption Dryers
Heatless Adsorption Dryers are used when the high quality compressed air is required. With activated alumina the heatless dryer can produce up to 40 C Pressure Dew Point and can be extended to -70 C by using molecular sieves
Working Principle
The Dryer utilizes two vertical pressure vessels filled with a desiccant such as activated alumina, silica gel or molecular sieve. The compressed air passes through the desiccant bed before being distributed to the plant. As the air passes through the desiccant, water vapour is removed from the air through a process called adsorption.
Adsorption is defined as the binding of molecules or particles = to a surface. The binding to the surface is usually weak and reversible. As the compressed air is passing through one vesset where water vapour is being adsorbed, the desiccant in the other vessel is undergoing regeneration where the water vapour that was previously adsorbed is removed. Regeneration is accomplished by extracting a portion of the dry air as it exits the active vessel, expanding this air to atmospheric pressure and passing it over the desiccant that is to be regenerated.
How Do Centrifugal Compressors Work?
Moisture Separators
Moisture separators also called water separators, cyclone separators, mechanical separators or centrifugal separators, use centrifugal motion to force liquid water out of compressed air. The spinning causes the condensate to accumulate on the walls and when the condensate gains enough mass it falls to the bottom of the separator’s bowl where it pools in the sump until it is flushed out of the system by the automatic float drain valve. Water contamination is a real problem, SPIN AQM's range of silicone-free water separators can deal simply and effectively with the problem. Typically, water separators are installed downstream of after coolers and air receivers, refrigerant dryers and at strategic points in pipe work installations. The design utilizes a finned internal spinner which removes large quantities of Aluminum body condensate and particulate by centrifugal action.
Down Stream Filters
Pre-Filter(5 Micron),or (1 Micron), Post Filter (Micron Filter 0.01), Carbon Filter (0.003Micron)
Purification of compressed air is needed because the air we breathe carries contaminants. Airborne particles, water, microbes and chemical gases enter compressors and in a compressed state these contaminants become concentrated and more destructive. In the compressed air system, hard particles assault equipment and piping. The result is damage to the system and generation of more particles. Examples of particles found in a compressed air system include desiccant dust, rust, pipe scale, metal oxides and dirt, which can be eliminated by applying proper filtration system.
