Features
High Pressure Capability: They are engineered to handle operating pressures that can exceed 4.5 MPa (45 barg). This makes them suitable for applications where air must be compressed to extremely high levels, far beyond the capabilities of conventional air dryers.
Robust Construction: These dryers are built with reinforced materials and components to withstand the stress and wear associated with high-pressure operation. This includes heavy-duty heat exchangers, high-strength refrigerant circuits, and durable moisture separators.
Efficient Moisture Removal: The dryers utilize advanced refrigeration technology to cool compressed air to low temperatures, causing moisture to condense and be separated from the air stream. They often maintain a pressure dew point (PDP) between 3-10°C, ensuring that the air is sufficiently dry for sensitive applications.
Versatile Cooling Options: Depending on the model, they can be either air-cooled or water-cooled. For larger capacity dryers, typically starting from 150 m³/min, water-cooled versions are available to manage the substantial heat loads more effectively.
Multiple Power Supply Options: These dryers accommodate different power supply configurations, including 220V/1Ph/50Hz/60Hz for smaller units and 380V/3Ph/50Hz/60Hz for larger units. This flexibility makes them adaptable to various industrial settings.
Advanced Control Systems: Equipped with sophisticated control systems, these dryers monitor and regulate the drying process to ensure optimal performance. This includes automatic drainage of collected moisture and protection mechanisms against overpressure or overheating.
