Сycling refrigeration dryers GDDF-ES with productivity from 3 to 4 m3/min

The GDDF-ES refrigeration cyclone dryers have been designed to provide the lowest possible cost by taking all cost drivers into account. This series is designed to work with variable speed compressors, such as the VS series compressors from Gardner Denver.

The cycling dryer is designed to deliver the lowest cost solution by focusing on all of the cost contributors. In a typical compressed air dryer, the refrigerant compressor runs continuously regardless of demand. 

Characteristics of the series:

• high efficiency
• stability under any load
• energy saving
• environmental friendliness
• user-friendly control system
• water and air-cooled models available

By shutting off the refrigerant compressor during low loads, Gardner Denver’s cycling dryers dramatically reduce energy consumption. Using environmentally-friendly R513A refrigerant with the lowest Global Warming Potential, also contributes to reducing greenhouse gas emissions. High quality components provide longer lasting dryers that require fewer replacement parts, again minimising impact on the environment.

The advantages of the series:

• Patented heat exchanger design achieves highest heat transfer efficiency in the industry, reducing compressor run time and therefore lowering energy costs
• Lowest pressure drop in the industry, averaging less than 0.2 bar g
• Thermal mass cold energy storage reduces dryer's compressor run time
• High quality air with ISO Class 4 dew point (+3°C)
• Smart drain - electronic no-loss drain eliminates compressed air loss
• R513A refrigerant also reduce energy consumption
• Advanced circuit design eliminates the need for thermal expansion valves and fan control switches
• True plug-and-play with single point connections for minimal installation costs
