Refrigerated compressed air dryer CGD

compact

Product Overview
The CGD Series refrigerated air dryers deliver ISO 8573-1 air quality with a pressure dew point typically in Class 4 to 5. They use the low-GWP refrigerant R513A and incorporate brazed aluminum heat exchangers and low pressure-drop designs for energy-efficient compressed air drying. Available capacities range from 7 to 50 SCFM. Units are certified to UL and CSA safety standards and ETL certified to UL60335-1 & 60335-2-40.

Features

• Utilizes R513A refrigerant with reduced Global Warming Potential (GWP).
• Constant pressure valve for stable operation across varying loads.
• Brazed aluminum heat exchanger for compact, corrosion-resistant performance.
• Low pressure drop design to minimize energy consumption.
• Simplified construction for straightforward maintenance.
• Certified: ETL to UL60335-1 & 60335-2-40; meets UL and CSA safety standards.

Benefits

• Helps meet sustainability and environmental regulations by using a low-GWP refrigerant.
• Stable pressure control reduces process variability and supports consistent downstream equipment performance.
• Durable brazed aluminum heat exchanger extends service life and improves thermal efficiency.
• Range of models (7–50 SCFM) suits small to medium industrial compressed air systems.
• Compact, service-friendly design lowers downtime and maintenance effort.
