Product catalog summary
Overview: The DK Series Refrigeration Dryers are designed for industrial applications, offering flexible performance, compact design, and economical operation. They maintain a 3°C pressure dew point with very low pressure drop and are suitable for tropical conditions, operating efficiently at a maximum inlet temperature of 60°C and ambient temperature of 50°C using R134a refrigerant.
Key Features:
  • Controllers: DIGIPRO controller for models up to DK130 and ESD controller for models from DK140.
  • Design: Compact design minimizes space usage. Easy access to components for maintenance.
  • Energy Efficiency: Equipped with digital controllers featuring economy modes and alarm capabilities.
  • Heat Exchanger: Aluminum heat exchanger ensures very low pressure drop (100mbar) and efficient operation.
  • Compressors: Scroll compressors from DK140 onwards, known for energy efficiency and durability.
  • Filters: Integrated compressed air filters up to DK210, with coalescing filters for water and oil removal.
  • Environmental Considerations: Optional R513A refrigerant available for lower Global Warming Potential (GWP).
Specifications:
  • Models: Range from DK10 to DK260, with varying dimensions and capacities.
  • Air Flow: Capacities range from 0.35 to 196.7 m3/min depending on the model.
  • Operating Conditions: Maximum working pressure of 16 bar, ambient temperature of 50°C, and inlet temperature of 60°C.
  • Voltage: Models operate on 230/1/50 or 400/3/50 voltage depending on the model.
Correction Factors: Factors for adjusting dryer capacity based on inlet temperature, ambient temperature, and pressure are provided to ensure optimal model selection.
Example Application: For a compressor delivering 200 m3/h at 6 bar with a dryer inlet temperature of 40°C and ambient temperature of 30°C, the correct dryer model is DK80, calculated using provided correction factors.
