How Do You Select And Size The Air Dryer For Air Compressor

The air compressor dryer can handle this maximum flow of compressed air. Pertama, the user needs to determine this value based on the consumption of all air-consuming equipment and the usage factor. Tentu saja, jika Anda sudah memiliki kompresor udara, you can send the nameplate to the manufacturer.

As a professional air compressor dryer manufacturer, kami memberi tahu Anda secara bertanggung jawab. Jika Anda menggunakan banyak udara, choose a compressed air dryer with a larger capacity. Itu adalah, kapasitas udara pengering harus lebih besar dari kompresor udara. Karena pada saat suhu dan kelembaban tinggi, kandungan air di udara meningkat. Pada saat ini, the dryer machine is overloaded. Jadi, the drying effect will decrease. Ini dapat menyebabkan banyak masalah, seperti sejumlah besar kelembaban dan kerusakan peralatan.

Different air pressures and different air capacities of the dryer. Tekanan umum dalam produksi industri berkisar dari 0,6MPa hingga 1,0MPa. Jadi, the most common is the normal pressure air compressor air dryer.

Namun, industri lain memiliki persyaratan tekanan yang berbeda. Misalnya, industri laser umumnya membutuhkan 16 bar. Some industries require high-pressure compressed air dryers. Perusahaan kami dapat menyesuaikan pengering hingga 100 batang.

Suhu sangat penting untuk pemilihan pengering kompresor udara. Misalnya, ada dua jenis pengering udara berpendingin. Namely normal temperature (50°C) and high temperature (80°C). The temperature is very high in Pakistan and the Middle East in summer. First, it must choose a high-temperature type of refrigerant dryer. Lebih-lebih lagi, kita sering harus memilih model yang lebih besar. This not only achieves good water removal but also avoids dryer downtime.

Di samping itu, suhu udara masuk pengering udara pengering umumnya tidak boleh lebih besar dari 40°C. If the temperature is too high, efek penghilangan air dari adsorben akan sangat berkurang. Tentu saja, it can choose the HOC type desiccant dryer now.

Different dew point requirements and different equipment configurations. Tentu saja, the price is different. Pengering berpendingin umumnya memiliki titik embun tekanan 2 sampai 10°C. There are different conditions and different dew points. Misalnya, refrigerant compressed air dryers can achieve a very low dew point. Tapi itu membutuhkan kondisi operasi standar 25 ° C dan 7 batang.
Industri yang berbeda memiliki persyaratan yang berbeda untuk titik embun. Berikut ini beberapa contohnya.

1. Industri farmasi: titik embun setidaknya -40°C.
2. industri PCB: titik embun harus mencapai -20°C.
3. Industri pemisahan udara gas: titik embun harus -70°C.

Choose a combination dryer if you require a dew point of -70°C. Atau harus ada pengering pendingin dan filter sebelum pengering udara adsorpsi.

Ini bervariasi dari satu negara ke negara. Misalnya, di Amerika Utara, 220V/60HZ/fase tunggal dan 380V/60HZ/3-fase adalah umum. Saat ini, perlu menyesuaikan kompresor pendingin. Terkadang harga dyer juga akan berbeda.

Some industries have requirements for the material of air compressor dryers. Misalnya, the pharmaceutical industry requires stainless steel. Pada kasus ini, sistem perpipaan dan pertukaran panas harus SS304. Dan menara adsorpsi juga membutuhkan SS304. Selain itu, industri baterai lithium juga membutuhkan baja tahan karat.

Pengering stainless steel akan lebih mahal. Tentu saja, you can choose the Lingyu PD series refrigerated air dryer. You can also choose the modular desiccant compressed air dryer. Mereka juga dapat memenuhi persyaratan industri makanan dan farmasi.

Refrigeran biasa dari pengering udara refrigeran adalah R22. Hal itu biasa terjadi di negara berkembang. Namun, Negara-negara Eropa dan Amerika membutuhkan refrigeran yang ramah lingkungan. Untuk kita, R134a, R407C, R410a tersedia. The dryer is a little more expensive if you want an eco-friendly refrigerant.

Pengering udara refrigeran aliran kecil berpendingin udara. Pengering berpendingin udara kami bisa sampai 120 m³/menit. Jika di atas 120 m³/menit, the air compressor air dryer is water-cooled.

For high-flow dryers, the size will be very large if you need an air-cooled type. Misalnya, itu akan setinggi beberapa lantai. Dan efisiensi pertukaran panas akan jauh lebih buruk. The water-cooled dryer is not affected by a high-temperature environment. Tentu saja, there needs to be a cooling water system. Jadi ini akan menambah biaya.

① Fixed vs. Variable Frequency Refrigerated Air Dryer

We commonly use fixed-frequency air compressor dryers. Itu dapat memenuhi output maksimum. Namun, in actual production activities, permintaan udara bervariasi. Pada tuntutan kecil, itu masih bekerja pada output maksimum. Hal ini menyebabkan pemborosan energi. Di sisi lain, the output of the variable frequency dryer can match the air demand. Hal ini menghasilkan penghematan energi dan biaya operasi yang signifikan.

② Choice of Desiccant Dryer Regeneration Method

The heatless compressed air dryer has a small power of ~0.1 kW. But it has a big air consumption of about 15%. Ini adalah konsumsi energi yang tinggi. Pengering pengering dengan pemanas mikro umumnya menghabiskan sekitar 8% udara regenerasi. Dibandingkan dengan pengering tanpa panas, itu bisa menghemat 40% energi.
Konsumsi pengering pengering kehilangan udara nol 0% udara regenerasi. A heatless air compressor air dryer can save 70% energi. Tentu saja, it is more expensive.

Measure or calculate the maximum compressed air flow rate that your air compressor system requires. This is usually expressed in cubic feet per minute (CFM). It is a crucial parameter for sizing the air dryer.

Determine the temperature and pressure of the compressed air at the dryer’s inlet. This information is necessary to calculate the corrected flow rate and dew point.

Account for variations in ambient temperature and humidity, as these can affect the performance of the air dryer. Understanding the environmental conditions helps in selecting the appropriate dryer type and specifications.

Define the desired dew point or moisture level for your application. The dew point is the temperature at which air becomes saturated with moisture and starts to condense. Choosing a dew point suitable for the application is crucial to prevent potential issues.

Choose the appropriate type of air dryer based on the required dew point and application. Common types include refrigerated dryers, desiccant dryers, and membrane dryers. Each type has specific advantages and is suitable for different dew point requirements.

Adjust the compressed air flow rate for the actual conditions using the information gathered earlier. Correcting for temperature and pressure ensures that the air dryer is sized accurately.

Refer to the manufacturer’s specifications and performance data for the selected air dryer type. So it can verify that it can handle the corrected flow rate and achieve the desired dew point.

Consider adding a safety factor to ensure the air dryer can handle variations in air demand and operating conditions, providing a buffer for unexpected fluctuations.

Based on the corrected flow rate, dew point requirements, safety factors, and manufacturer specifications, select the suitable size and model of the air dryer that meets the system’s needs.

Install the chosen air dryer correctly within the compressed air system. Regularly monitor its performance and maintain it according to the manufacturer’s recommendations to ensure optimal efficiency and reliability.
