Refrigerated Air Dryers

For GD Compressors, quality and efficiency is just as important for compressed air treatment as it is for compressed air generation.

With the cost of electricity being so high, any technology which can reduce the amount of power needed by the air dryer is essential. Gardner Denver has developed a range of different dryer technologies, refrigerant, sub freezing and absorption (or desiccant) dryers as shown on this page which can give energy savings depending on the process the air is serving.

Our range of cycling dryers shut off the refrigerant compressor during low loads, which dramatically reduces energy consumption as shown in this graph. Using environmentally-friendly R513A, R407C refrigerants with the lowest Global Warming Potential, also contributes to reducing greenhouse gas emissions.


Focused on energy saving

The GDDF-series of refrigeration air dryers has been designed to maximise efficiency and reliability. All models are equipped with a high efficiency heat exchanger including an integrated condensate separator. The heat exchangers, completely designed and developed in our labs, are capable of achieving the highest levels of performance required from the market, together with a very low pressure drop rate.


Innovative Control Panel

With all the main functions you would expect to control and monitor the unit:

  • Anti freeze mode – shuts dryer off to avoid icing
  • Alarm display: dew point, high/low temperature, high ambient temperature
  • Remote ON/OFF (optional)
  • Alarm history
  • Condensate drain management

GDD4F – GDD80F: Electronic drain valve

The programmable electronic drain valve is a standard feature (up to GDD80F) and is fully adjustable to help minimise air loss.

  • Easily adjusted from the dryer control panel to match all possible working conditions.
  • Proven reliability – thousands in service.
  • Includes a strainer for quick maintenance. 

GDD100F – GDD1920F: No-loss Drain

The powerful no loss electronic drain is standard from GDD100 and above, optional on all other models, and eliminates the need for pre-setting the unit. It uses state of-the-art software combined with a special transducer interface to measure the presence of condensate so that it is released only when needed. Continuous monitoring ensures fast and effective discharge of the condensate with no deficit of compressed air.
