The impact of core suction dryers on the quality of compressed air
Thread Content
Currently, three common technologies are used in industry for the drying of compressed air: refrigerated dryers, twin-tower adsorption dryers, and modular adsorption dryers. The Betten core dryer represents an upgraded version of these three technologies. Developed by Betten Company, this core adsorption drying technology manages to reduce the amount of adsorbent required to just 30% of that needed in traditional twin-tower adsorption dryers. It also solves the problems associated with traditional adsorption dryers, such as uneven airflow distribution, areas where adsorption does not occur effectively, low efficiency in using adsorbents, and high energy consumption. Features of the core drying machine: High efficiency in absorption – It is Betten’s mission to provide customers with compressed air that is clean, dry, and meets industry quality standards. Betten’s core drying machines are capable of maintaining a pressure dew point between -20°C and -70°C in a consistent and stable manner. Low energy consumption – Apart from the power used by the low-power controller, Betten’s core drying machines have no other electrical energy losses (except in the case of models with thermal regeneration). Durable use: The Beton dryer employs the latest core adsorption technology ； All core components are manufactured using standardized processes for professionalism; the adsorbent does not need to be filled on-site, thereby completely eliminating the problems associated with secondary filling of the adsorbent in adsorption dryers, such as difficulties in filling and incomplete packing ； It also makes the equipment easier and more convenient to maintain, repair, and service, ensuring the consistency of the drying effect. The Betten core dryer also has many advantages such as a small size and high safety levels ； It helps to save space required for the equipment. Since the mold core does not fall under the category of pressure vessels, it not only saves you the costs and time associated with inspections of pressure vessels. The Betten core suction dryers and high-efficiency precision filters not only provide the technical basis for completely eliminating issues such as water, oil, and dust in compressed air, but also reduce energy consumption compared to traditional purification equipment. The heat-free model requires 5% of recycled gas, while the mild-heat model needs only 2% of recycled gas, **reducing the energy consumption and production costs for enterprises.
Compressed air adsorption dryers are used to remove gaseous water from compressed air to meet the water content standards specified in ISO8573: Class 1 requires a pressure dew point of -70°C, Class 2 requires -40°C, and Class 3 requires -20°C. Commonly used cold dryers can only achieve up to Class 4, with a pressure dew point of +3°C. Filters can only remove some of the liquid water; they are ineffective against gaseous water. In other words, if a dew point below -20°C is required, an adsorption dryer is the ideal choice. The earliest form of adsorption dryers was of the twin-tower design, utilizing two pressure vessels; the size of these vessels could be increased or decreased depending on the volume of material to be processed, and in theory, the processing capacity could be made extremely high as long as the vessels were large enough ； Module dryers are made compact through modular tanks, and their multi-tube configuration ensures a compact overall design as well as stable drying performance. If they feature a design that allows the adsorption tubes to be replaced, they are commonly referred to as core dryer units. Foshan Deyue Purification Technology specializes in the production of module-based, modular, and dual-core suction dryers; these products enjoy a high reputation in the industry. It is guaranteed that the dew point will remain within the range of -20°C to -70°C under standard operating conditions, with a warranty period of up to 3 years.
