The characteristics determined by the partial pressure of water vapor in compressed air and the temperature of compressed air are used for cooling, dehydration and drying. While keeping the compressed air pressure basically unchanged, lowering the temperature of the compressed air can reduce the water content in the compressed air, and the excess water vapor will condense into liquid. The refrigerated dryer uses this principle to dry compressed air using refrigeration technology, so the refrigerated dryer has a refrigeration system. Refrigerated air dryer working Refrigerated air dryer how it works The refrigerated dryer sucks the low-pressure (low-temperature) refrigerant in the evaporator into the compressor cylinder. After the refrigerant vapor is compressed, the pressure and temperature increase at the same time; the high- pressure and high-temperature refrigerant vapor is pressed to the condenser. The higher temperature refrigerant steam exchanges heat with the lower temperature cooling water or air. The heat of the refrigerant is taken away by water or air and condensed, and the refrigerant vapor becomes a liquid. This part of the liquid is then transported to the expansion valve, flows through the expansion contact into a low-temperature and low-pressure liquid and enters the evaporator; in the evaporator, the low-temperature, low-pressure refrigerant liquid absorbs the heat of the compressed air and vaporizes (commonly known as "evaporation") , and the compressed air condenses out a large amount of liquid water after being cooled; the refrigerant vapor in the evaporator is sucked away by the compressor, so that the refrigerant goes through four processes of compression, condensation, throttling, and evaporation in the system, thus Completed a cycle.

OIL INJECTED SCREW COMPRESSOR VS RECIPROCATING PISTON COMPRESSOR Piston air compressors use the piston to reciprocate in the cylinder to compress the air. They have high noise and vibration and many wearing parts. After the piston rings are worn, the air volume will decrease causing the decreased efficiency. The oil injection screw compressor mainly consists of a screw and star wheels to form a compression chamber. The air compression process is completed through the rotation of the screw which has higher requirements for processing accuracy because higher accuracy means higher volumetric efficiency. The noise and vibration are small, the unit has basically no wearing parts so the maintenance cost is low. HOW DO OIL INJECTED AIR COMPRESSOR WORK？ The main components of an oil free vs oil injected compressor are the air end, motor, oil and gas separation tank and cooler. Since the oil requires a higher temperature to ensure its good lubricity, the oil injected air compressor is generally air-cooled. The air is filtered by the filter element and then sucked into the air end for compression. Lubricating oil is injected into the air end for lubrication and sealing. The compressed oil and gas mixture is separated by the separation core in the oil and gas separation barrel to get compressed air with an oil content of less than 2ppm. After being cooled by the air-cooled cooler, the high-temperature oil returns to the compression air end and circulates continuously.

Pure water instead of lubricating oil is used in air end for lubrication. Air end and all parts contacting with water are made of 304 food grade stainless steel. Compressed air passes TUV oil free test and also meets requirements of FDA and GMP. With no oil in the whole machine, maintenance is simple which only requires the replacement of air and water filter. Water injected screw compressor adopts a direct coupling method between the air end and the motor, resulting in high transmission efficiency. Due to the direct injection of water for cooling circulation, the unit operates at a very low temperature which is around 45 degrees Celsius. Working Principle Of CMN No Oil water injected compressor The single screw air end is composed of a main screw and two symmetrically arranged flat star wheels to form a meshing pair, installed inside the stainless steel shell. The screw's groove, the inner wall of the air end shell, and the tooth surface of the star wheel constitute the compression chamber. The motor directly drives the rotation of the screw shaft, which drives the rotation of the star wheel. The gas enters the screw groove through the suction port, undergoes compression, and is then expelled through the exhaust port on the air end shell. There are spray holes on the air end shell for injection of lubricating oil or water into the compression chamber, serving as sealing, cooling, and lubricating functions. Air is sucked into the air end through the air filter, getting compressed in the air end. During compression, water in injected into air end to cool and lubricate. Water gas mixture then is separated in gas water separator and compressed air is discharged from the minimum pressure valve on the top of the gas water separator to the user. Water remains at the bottom of gas water separator, being cooled by the water cooler or air cooler, and goes to air end for compression again.

A biometric fingerprint module is a compact and secure device used for capturing and processing fingerprint images. It includes a sensor for capturing fingerprints and an embedded processor for image processing, feature extraction, and matching. These modules are widely used in security systems, access control systems, and identification applications due to their high accuracy and reliability. WHAT ARE THE USES OF A FINGERPRINT MODULE? Access Control: They can be used in buildings, offices, or secure areas where access needs to be controlled and restricted to authorized individuals. Time and Attendance Systems: Businesses often use fingerprint modules to track employee attendance accurately, eliminating the possibility of 'buddy punching’. Law Enforcement: Police and other law enforcement agencies use fingerprint modules for criminal identification and background checks. Personal Devices: Many smartphones, laptops, and other personal devices now come with built-in fingerprint modules for secure and convenient user authentication. Banking and Financial Services: Fingerprint modules are used in ATMs and other banking applications for secure customer authentication. Healthcare: In healthcare settings, fingerprint modules can be used to accurately identify patients and ensure that medical records are correctly matched to the right individual. HOW ACCURATE IS A FINGERPRINT MODULE? Fingerprint biometric modules are generally highly accurate due to the unique nature of fingerprints. Each individual has unique fingerprints with distinct ridge patterns and minutiae points (specific points of interest in a fingerprint, like where ridges split or end). The accuracy of a finger print scanner module depends on the quality of the sensor and the algorithm used to compare the fingerprints. High-quality sensors can capture high-resolution images, which allow for more detailed comparison and thus higher accuracy. The algorithm used to compare the fingerprints also plays a crucial role in the accuracy of the system. However, it's important to note that while the chances of false matches (different individuals fingerprints being identified as a match) are extremely low, they are not zero. The system's accuracy can also be affected by factors such as dirty or worn-out sensors, poor quality or partial fingerprints, and environmental conditions. In terms of numbers, many fingerprint systems claim to have a False Acceptance Rate (FAR) - the likelihood that the system incorrectly accepts an access attempt by an unauthorized user - of less than 0.001%. The False Rejection Rate (FRR) - the likelihood that the system incorrectly rejects an access attempt by an authorized user - can vary more, but is typically kept low to ensure user convenience.
