A complete buyer's guide to rotary screw air compressors with dryers

Dryers are essential in various industries for removing the water created by compressed air, which can lead to corrosion and damage to downstream equipment.  

The dryers in the air compressor with dryer package help maintain the quality of compressed air by suppressing the dew point and preventing issues such as frozen pipes, contamination, and water buildup. There are different types of air dryers, including refrigerated, desiccant, and deliquescent, each suitable for specific requirements and moisture tolerance levels. 

The importance of using a compressed air dryer lies in the fact that moisture is inevitable in air compression and can lead to significant problems such as corrosion, frozen pipes, and equipment damage. Therefore, air dryers are crucial for maintaining a well-functioning compressed air net and ensuring the production of pure, clean compressed air for various industrial applications. 

Rotary screw air compressors, which are commonly used in industries for material handling, spray painting, and machine tools, benefit from the continuous delivery of air provided by these compressors. The integration of air dryers with rotary screw compressors is important for preventing damage to pneumatic machinery, piping, valves, and other components, as well as avoiding potential contamination of end products. 

Rotary screw air compressors are designed for continuous operation, providing a consistent air flow with a 100% duty cycle. Unlike piston compressors, which require downtime, 5 hp rotary screw compressors are built to run 24/7, making them ideal for applications that demand uninterrupted air supply.

These compressors are available with integrated air dryers, such as refrigerated, desiccant, or deliquescent dryers. The integrated dryers help remove excess moisture from the compressed air, preventing corrosion, frozen pipes, and damage to downstream equipment. This integrated solution ensures the production of clean, dry compressed air, making the compressors suitable for a wide range of industrial applications.

Rotary screw compressors with dryers offer high efficiency and reliability. They are equipped with energy-saving features, such as Variable Speed Drive (VSD) technology, which adjusts the motor speed to match the air demand, resulting in reduced energy consumption. Additionally, these compressors are built with high-quality components, offering a long service life.  

Rotary screw air compressors offer several benefits, making them essential in various industries. Here's an analysis of the advantages they provide:

The integrated dryers in rotary screw air compressors help remove excess moisture from the compressed air, preventing corrosion, frozen pipes, and damage to downstream equipment. This ensures the production of clean, dry compressed air of 125 psi, making the compressors suitable for a wide range of industrial applications.

Rotary screw compressors are generally energy efficient and consume less oil than other types of compressors. They are equipped with features such as Variable Speed Drive (VSD) technology in 3-phase rotary screw air compressors, which adjusts the motor speed to match the air demand, resulting in reduced energy consumption. This makes the rotary screw air compressors from Atlas Copco a cost-effective choice for compact compressors with maximum efficiency.

These variable-speed rotary screw air compressors are designed for continuous operation, offering a 100% duty cycle and high reliability. They have fewer moving parts than other types of compressors, leading to reduced wear and tear, lower maintenance costs, and an overall longer lifespan. Additionally, the integrated drying technology helps prevent damage to pneumatic machinery, piping, and valves, contributing to the longevity of the equipment.

When considering the purchase of a rotary screw air compressor with a dryer, it's essential to evaluate the specific requirements of the application. 

Here are some more key considerations:

Determine the required airflow (measured in cubic feet per minute, CFM) for the 125 psi tools and equipment that will be powered by the compressor. Consider a higher CFM to accommodate future needs and ensure proper functionality of all tools. Evaluate the physical dimensions of the air compressor with a dryer package to ensure it fits the available space in the facility.

Consider the type of integrated air dryer (e.g., refrigerated) based on the specific moisture tolerance levels and air quality requirements of the application.

Using Atlas Copco, determine whether a single-phase or three-phase compressor is needed based on the available electrical supply. Consult with an electrician if necessary while installing the volt rotary screw air compressor.

Establish a budget for the purchase of the rotary screw air compressor, considering the initial investment and long-term operating costs, including energy consumption and maintenance.

To maximize the lifespan and efficiency of rotary screw compressors, it is important to follow proper maintenance and operational tips. Here are some tips to consider while purchasing a variable speed rotary screw air compressor: be sure to select one with a 125-gallon tank for maximum efficiency.

• Follow Atlas Copco's recommended maintenance schedule, including regular oil changes, air and oil filter replacement or cleaning, and checking the condition of drive belts or couplings. 

• Conduct regular maintenance, including checking the belts and couplers for correct tensioning and tightening connections. 

• Use genuine parts from the manufacturer to ensure optimal performance and conform to the specifications of the equipment. 

• Clean exposed surfaces, particularly heat exchanger fins, every week to prevent overheating and detect any abnormal temperature rise.

• Ensure the operating area for the 3-phase rotary screw air compressor is sufficiently ventilated during usage hours to ensure proper motor health. 

• Use the appropriate type of integrated air dryer based on the specific moisture tolerance levels and air quality requirements of the application. 

• Adjust service intervals for the compressor to allow for a more challenging environment. 

• Seek outside help from factory-trained air compression experts when problems arise. 

• Cut off the compressed air supply when conducting compressor servicing, which should be performed on an hours-running basis.
