Refrigeration dryers

AD 15-4200

Pneumatech’s AD 15-4200 non-cycling refrigeration dryers are designed to efficiently protect compressed air systems by reducing moisture, making them ideal for a wide range of industrial applications.

Lower energy costs

Efficient moisture removal

The AD 15-4200 range features zero-loss drains that remove moisture without wasting compressed air, maximizing system efficiency and saving energy costs. This makes it a smart and cost-effective choice for industrial applications.

Reliable performance

Stable operation

The Pneumatech AD 15-4200 dryers offer superior reliability by using a hot gas bypass valve, which prevents ice formation during low airflow. This ensures consistent performance and protects the dryer, making it a dependable solution for industrial applications.

Smart monitoring

Always in control

The Pneumatech AD 15-4200 range features a new controller with real-time PDP monitoring, remote alarms for maintenance alerts, and a remote start/stop feature, providing enhanced control and operational efficiency.

AD 15-4200 Non-Cycling Refrigeration Dryers

Pneumatech’s AD 15-4200 non-cycling refrigeration dryers are designed to protect compressed air systems by reducing moisture levels. Featuring a modern controller with real-time PDP monitoring and zero-loss electronic drains, they ensure maximum efficiency without air loss.

The AD15-105 uses eco-friendly R513A refrigerant to lower global warming potential, while the AD125-4200 models combine rotary compressors with R410A refrigerant, improving energy efficiency by up to 30% and complying with EU regulation 517/2014. The reliable rotary compressors also reduce vibration and stress, achieving a stable pressure dew point of up to 3°C/37°F.

Refrigeration dryer technology

Refrigeration dryers, available in air-cooled or water-cooled models, cool the warm, moisture-laden air from the compressor. This process begins in the air-to-air heat exchanger and continues in the air-to-refrigerant heat exchanger, where moisture condenses and is drained. The air is then reheated to room temperature, lowering the pressure dew point and preventing condensation on the piping. This heat exchange also reduces the refrigerant system’s cooling demand by cooling the incoming air. Refrigeration dryers come in both cycling and non-cycling variants, with non-cycling models maintaining a constant refrigerant flow, ensuring stable operation. As the most widely used drying technology, refrigeration dryers have a broad range of applications.

Discover the key features of the AD 15-4200

Pneumatech’s AD 15-4200 non-cycling refrigeration dryers come packed with innovative features designed to enhance the performance and efficiency of your compressed air system. Equipped with a new digital controller, these dryers offer real-time pressure dew point (PDP) monitoring, ensuring precise control over air quality. The zero-loss electronic drains eliminate unnecessary compressed air waste, maximizing efficiency. The carefully engineered heat exchangers provide superior cooling performance, making these dryers an ideal solution for industrial applications. The AD 15-105 models introduce the eco-friendly R513A refrigerant, significantly reducing global warming potential, while the AD 125-4200 models boast a rotary compressor paired with R410A refrigerant. This winning combination improves energy efficiency by up to 30%, reduces refrigerant gas usage by 20%, and complies fully with European regulation EU No 517/2014, all while achieving a stable dew point of 3°C (37°F). These advanced features make the AD 15-4200 range both highly efficient and environmentally responsible.
