Product Characteristics

Stable and Consistent Dew Point Control: One of the key working characteristics of refrigerated air dryers is their ability to maintain a stable and consistent dew point, which is critical for protecting downstream equipment and ensuring product quality. Unlike adsorption dryers that may experience dew point fluctuations during the regeneration cycle, refrigerated dryers achieve stable dew point control through precise temperature regulation of the refrigerant system. Equipped with advanced temperature sensors and a microprocessor-based control system, the dryer continuously monitors the temperature of the compressed air in the evaporator and adjusts the operation of the compressor, expansion valve, and fan accordingly. This ensures that the air is cooled to the preset dew point temperature consistently, even when there are fluctuations in the inlet air temperature, pressure, or humidity. The stable dew point prevents condensation in pneumatic lines, valves, and tools, which can cause corrosion, wear, and malfunction. For most standard refrigerated dryers, the dew point can be maintained at 2°C to 10°C (pressure dew point), which is sufficient for applications in automotive manufacturing, food processing, electronics, and other industries that require dry compressed air.

Supply of 100% Genuine Spare Parts: To ensure the stable operation, performance, and service life of your chiller, we provide 100% genuine spare parts for all our chiller products, including compressors, filters, lubricating oil, expansion valves, sensors, control panels, and other components. All genuine spare parts are manufactured in strict accordance with the original product standards, ensuring perfect compatibility with your chiller and reliable performance. You can purchase genuine spare parts through our official website, after-sales hotline, or authorized distributors. We offer a 12-month warranty on all genuine spare parts, covering any quality defects. In addition, our after-sales team can provide professional guidance on the replacement of spare parts, and if you need assistance, we can arrange for a technician to replace the spare parts for you at a reasonable fee. We strongly remind you not to use counterfeit or inferior spare parts, as they may damage the chiller, affect its performance, and void the product warranty.​
5. Regular Maintenance and Inspection Services: Regular maintenance is crucial to extending the service life of the chiller, improving energy efficiency, and reducing the probability of faults. We provide professional regular maintenance and inspection services for all our chillers. According to the chiller model, usage environment, and operating hours, we formulate a personalized maintenance plan, usually with a maintenance cycle of 3 months, 6 months, or 12 months. Our maintenance services include thorough cleaning of the condenser, evaporator, and filter, inspection of the compressor, fan, and circulating pump for wear and tear, detection of refrigerant leakage, replacement of lubricating oil and filters, calibration of the control system and temperature sensor, and testing of the chiller's cooling capacity and energy efficiency. After each maintenance, we will provide a detailed maintenance report, indicating the operating status of the chiller, potential problems, and maintenance suggestions. For customers who purchase our annual maintenance package, we offer preferential prices, priority service, and free replacement of small wear parts.

1. Q: What happens if water accumulates inside?
A: Poor dew point, pipe corrosion, wet air, contaminated evaporator.

2. Q: Can manual drain replace auto drain?
A: Temporary only; long-term use causes water buildup.

3. Q: Quick check for poor drainage?
A: Open manual drain; if water flows out, the auto drain is faulty.

4. Q: Causes of high refrigerant pressure alarm?
A: Dirty condenser, fan failure, high ambient temp, overload.

5. Q: Causes of low refrigerant pressure alarm?
A: Refrigerant leakage/low charge, clogged filter, expansion valve fault, freezing.
