With flow rates reaching up to 14400 m³/h, the AC 2650-4200 & AC 2650-8500 VSD ranges are ideal for high-demand industrial environments, ensuring efficient performance across a wide range of air flows.

AC 2650-4200 & AC 2650-8500 VSD Cycling Refrigeration Dryers

AC 2650-4200 & AC 2650-8500 VSD represent Pneumatech’s advanced range of refrigeration dryers, designed for high flows between 4500 and 14400 m³/hr.

Engineered in-house and rigorously tested under stringent conditions, including ambient temperatures up to 46°C, these dryers surpass international compressed air purity standards and comply with ISO 7183:2007. Featuring innovative technologies, they excel in continuous and varying air demand applications.

With high-efficiency components and smart design, users can achieve energy savings of around 50%, resulting in reduced power consumption and a lower carbon footprint.

Refrigeration dryer technology

Refrigeration dryers, available in both air-cooled and water-cooled versions, work by cooling the warm, moisture-laden air generated by the compressor. The cooling begins in the air-to-air heat exchanger and continues in the air-to-refrigerant heat exchanger, where moisture is condensed and drained. Afterward, the air is reheated to room temperature, reducing the pressure dew point and preventing condensation within the piping system. By cooling the incoming air, the process also decreases the cooling demand on the refrigerant system. Widely adopted across many sectors, refrigeration dryers are the most commonly used drying technology today.

Key features

Variable Speed Drive technology

The AC 2650-8500 VSD range is equipped with cutting-edge Variable Speed Drive (VSD) technology, offering a significant boost in the energy efficiency of refrigerated air dryers. The system uses an inverter to automatically adjust the motor's speed according to the real-time demand for compressed air, leading to optimized energy consumption and lower running costs.

During times of lower demand, the dryers slow down to conserve energy, while still providing full capacity when required. This approach not only enhances energy efficiency but also reduces wear on components and extends the overall lifespan of the equipment. With a strong emphasis on performance and sustainability, the AC 2650-8500 VSD delivers a new level of energy-efficient air treatment.

Key features

Advanced Purelogic Touch controller

The AC 2650-4200 VSD and AC 2650-8500 VSD ranges feature the advanced Purelogic Touch controller, delivering an enhanced user experience and improved operational efficiency. This intuitive interface provides real-time monitoring, seamless adjustment of settings, and optimized performance control.

With remote access to system data, users can analyze performance, troubleshoot issues, and ensure continuous air quality from any location. This leads to increased energy efficiency, simplified maintenance, and reduced downtime, all contributing to reliable and efficient operation.
