BLR 10-750 A/W Refrigerated Air Dryers

The BLR 10-750 A/W Refrigerated Air Dryers are high-capacity models in the Bolaite BLR series of refrigerated air dryers, specifically engineered for industrial applications requiring large-scale, continuous, and stable air supply. This equipment utilizes heat exchange between refrigerant and compressed air to condense and separate saturated water vapor, achieving deep drying of compressed air. As a core product line of Bolaite’s air treatment equipment, the BLR series has undergone three generations of technological iterations, designed with core concepts of high-efficiency dehumidification, energy conservation, and intelligent control.

BLR 10-750 A/W Refrigerated Air Dryers Working Principle

The working process of the refrigerated air dryer is based on the synergistic effect of the refrigeration cycle and compressed air heat exchange. The specific process is as follows:

• Pre-cooling Stage: High-temperature, high-humidity compressed air first enters a high-efficiency three-in-one plate-fin heat exchanger, exchanging heat with already cooled exhaust air for initial cooling. This design allows the inlet temperature difference to be as low as 5°C, significantly improving heat recovery efficiency.
• Deep Cooling Stage: The pre-cooled air enters the evaporator for heat exchange with the refrigerant. The refrigeration system is driven by an industrial-grade refrigeration compressor, which compresses the refrigerant and sends it to the condenser for heat dissipation. It then passes through an expansion valve into the evaporator, absorbing heat from the compressed air and rapidly lowering the air temperature below the dew point.
• Gas-Liquid Separation Stage: In the cooled compressed air, water vapor condenses into liquid water, which is separated by a high-efficiency water separator. The water separation efficiency of this separator is as high as 99%, ensuring the dryness of the outlet compressed air.
• Reheating and Output Stage: The dried low-temperature air passes through the plate-fin heat exchanger again to exchange heat with the inlet high-temperature air. The temperature rises before output, achieving cascade utilization of energy.

BLR 10-750 A/W Refrigerated Air Dryers Functions and Features

High-Efficiency Dehumidification Capability

The BLR series adopts a high-efficiency three-in-one plate-fin heat exchanger, integrating pre-cooling, evaporation, and reheating into a single unit. The inlet and outlet temperature difference of this heat exchanger can be controlled to as low as 5°C, minimizing cooling loss while ensuring dehumidification effectiveness. Combined with a high-efficiency water separator with 99% water separation efficiency, the relative humidity of the outlet compressed air can be as low as 20%, effectively eliminating the risk of pipeline corrosion.

Significant Energy-Saving Performance

Compared to traditional dryers using shell-and-tube heat exchangers, the BLR series adopts a plate-fin heat exchanger design, reducing energy consumption by up to 50%. Meanwhile, the use of R410A eco-friendly refrigerant not only reduces system operating pressure loss but also aligns with the current green and low-carbon development trend of industrial equipment.

Industrial-Grade Reliability

The BLR series has multiple guarantees in reliability design: core components use industrial-grade international brand refrigeration compressors to ensure stability during long-term continuous operation; the pipeline design is optimized, with only 4 manual welding points in the whole machine, significantly reducing the risk of leakage. Every unit must pass three-level leak testing with compressed air, helium, and refrigerant before leaving the factory to ensure the sealing performance of the delivered product meets standards.

Intelligent Control

The equipment is equipped with a new intelligent display, integrating real-time dew point temperature display and fault alarm functions. Operators can intuitively monitor the operating status of the dryer and promptly identify and address abnormalities.
