Energy efficiency

Savings with VSD

Equipped with Variable Speed Drive (VSD) technology, the AC 765-2120 VSD dryers adjust motor speed to match air demand, cutting energy consumption by up to 60%, even during partial load conditions.

Reliable design

Stable & efficient drying

The Variable Speed Drive (VSD) works alongside automatic expansion and hot gas bypass valves to ensure a constant dew point and smooth performance, even when operating conditions vary.

Easy installation & maintenance

Plug & play convenience

Simple to install and easy to maintain, these dryers feature accessible pipe connections, long service intervals, and quick access to key components, helping minimise downtime.

AC 765-2120 VSD Cycling Refrigeration Dryers

The AC 765-2120 VSD is Pneumatech’s premium refrigeration dryer range for higher flows – from 1296 to 3600 m3/h. It delivers strong drying performance, superior reliability, and significantly reduced operating costs, thanks to its energy-saving controls and algorithms, low pressure drop, and quality components.

 

Dedicated variable speed drive (VSD) variants are available in both ranges to reduce energy use by as much as 60% compared to conventional dryers and ensure a stable dew point.

Refrigeration dryer technology

The air-cooled refrigeration dryers remove moisture from the warm, compressed air. The air first passes through the air-to-air heat exchanger before moving to the air-to-refrigerant heat exchanger, where the moisture is condensed and drained. The air is then reheated to room temperature, lowering the pressure dew point and preventing condensation in the piping. This heat exchange process also reduces the cooling demand of the refrigerant system by pre-cooling the incoming air. Refrigeration dryers are a popular drying method and are widely used across multiple industries.

Key features

Variable Speed Drive technology

The AC 765-2120 VSD range features advanced Variable Speed Drive (VSD) technology, transforming the efficiency of refrigerated air dryers. Controlled by an inverter, the motor speed adjusts in real-time to match compressed air demand, optimizing energy use and significantly lowering operating costs.

By operating at lower speeds during low demand while ensuring full capacity when needed, these dryers enhance energy efficiency, reduce component wear, and extend lifespan. With a focus on performance and sustainability, the AC 765-2120 VSD sets a new benchmark for energy-efficient air treatment solutions.
