Once the leakage current exceeds the set value, it will quickly cut off the power supply to prevent electric shock accidents. Be sure to select an earth leakage circuit breaker of appropriate capacity to match the electrical equipment and circuit load.
Voltage Stabilizer: For the proper operation of electrical equipment, stable voltage is crucial. Excessive voltage fluctuations and fluctuations can negatively affect the performance and lifespan of your equipment. Installing a voltage stabilizer can stabilize the power supply voltage and prevent excessive high or low voltage fluctuations from causing damage to equipment. According to the actual situation and equipment requirements, select a voltage stabilizer of appropriate capacity and type.
Inspection and maintenance: Regularly check the voltage and current of electrical equipment to ensure that the voltage is within the required rated range of the equipment, and pay attention to whether there are abnormal fluctuations. Regularly maintain and clean electrical equipment, keep connections in good condition, and promptly repair any electrical faults or problems.
Consult a professional: If you have any questions about the selection of an earth leakage circuit breaker or the installation of a voltage stabilizer, it is recommended to consult a professional electrical engineer or a professional in a related field. They can provide more accurate and professional advice based on your specific needs and on-site conditions.
If the compressed air inlet temperature is too high, it may negatively affect the performance and reliability of the compressed air system and equipment. The following are some possible causes of excessively high compressed air inlet temperatures and their corresponding solutions:
High ambient temperature: If the ambient temperature is high, such as in summer or in hot environments, the compressed air inlet temperature may increase. Solutions include providing adequate ventilation and cooling, ensuring good air circulation around compressed air equipment, and avoiding installing equipment in closed thermal environments.
Overheated compressor: Overheating of the compressor itself may cause the compressed air inlet temperature to rise. This may be caused by cooling system failure inside the compressor, overload operation, or unreasonable compressor design. In this case, the cooling system of the compressor should be inspected and repaired, and the operating load of the compressor should be ensured to be within a reasonable range.
High-humidity environments: High-humidity environments may cause the compressed air inlet temperature to increase because moisture in the air increases the cooling load on the compressor. In this case, consider installing a humidity control device or dryer to reduce the humidity of the inlet air and reduce the load on the compressor.
Improper air inlet filtration: If the air inlet filter is clogged or incorrectly selected, it can restrict air flow and cause the compressor to overheat. Make sure the air inlet filter is clean and select the appropriate filter based on equipment requirements to maintain good air circulation.
Poor compressor maintenance: Unscheduled maintenance and cleaning can cause excessive dirt and particulate matter to accumulate inside the compressor, hindering cooling and causing overheating. Perform regular compressor maintenance and cleaning, including removing dirt from filters, coolers, and radiators.
If the compressed air quality of the refrigerated dryer is poor, it can have a negative impact on the equipment and process.
Moisture and Humidity: Moisture in compressed air is a common problem that can lead to equipment failure, pipe corrosion and product quality issues. Solutions include installing appropriate coolers and dryers to remove moisture, regularly draining condensate, and ensuring that the compressed air system’s pipes and tanks are dry.
Oil contamination: If there is a leak or failure in the oil lubrication system in the compressor or compressed air system, it can cause oil to contaminate the compressed air. This can have a negative impact on equipment and processes. Solutions include regular inspection and maintenance of the lubrication system, repairing any leaks, and installing an oil-water separator to separate oil contaminants.
Particles and contaminants: Particles and contaminants in compressed air can come from airborne dust, pipe corrosion, or wear and tear within the compressor. These substances may affect the normal operation of equipment and product quality. Solutions include installing appropriate filters to capture particulate matter and contaminants, as well as regular cleaning and filter replacement.

Regular maintenance: Regular maintenance of your compressor and compressed air system is very important. This includes cleaning and replacing filters, checking and repairing leaks, keeping lubrication systems operating properly, etc.
Cleaning your dryer vent is an important step in keeping your compressed air system functioning properly and improving air quality.
Turn off the power: Before cleaning the vents, make sure the dryer is turned off and disconnected from the power source to ensure safe operation.
Prepare your tools: Have the appropriate tools, such as a brush, hair dryer, or compressed air gun, to remove dust and debris from your vents.
Remove dust and debris: Use a brush or hair dryer to gently remove dust and debris from the vents. Make sure that dust and debris are blown away from the top of the vents to prevent them from entering the inside of the dryer.
Compressed air spray gun cleaning: If you have a compressed air spray gun, you can use it to blow away dust and debris from hard-to-reach areas. Make sure to use the proper pressure and angle to avoid damaging the vents or blowing dust into the interior of the dryer.
Check the filter: There may be a filter installed near the vent, check the condition of the filter and clean or replace if necessary. Cleaning or replacing the filter can improve the effectiveness of your vents and prevent dust and dirt from entering your dryer.
Regular maintenance: To ensure your vents are clean and working efficiently, regular maintenance is recommended. Develop an appropriate maintenance schedule based on your dryer usage and environmental conditions, and clean and inspect vents as scheduled.
When cleaning the dryer vent, ensure safe operation and avoid using excessive pressure or tools to avoid damaging the equipment or causing accidents.
Under normal circumstances, when the refrigeration dryer is turned on again after being shut down, it is recommended to wait for a period of time to ensure that the compressed air in the system is cooled and discharged. This is to avoid the following situations that may occur on reboot:
Condensate Drainage: Refrigeration dryers are often used to remove moisture from compressed air, but after shutdown, condensate can accumulate in the system. Waiting for a period of time will help the condensate drain out during the shutdown so as not to affect the normal operation of the system.
Compressor cooling: The compressor generates heat when it is running, and it takes a certain amount of time to cool down after it is shut down. If restarted immediately, excessive temperatures and pressure may result, adversely affecting the equipment. Waiting for a while will ensure that the compressor has cooled sufficiently to maintain its normal operating temperature range.
Exactly how long you need to wait depends on the model and size of the dryer, as well as how recently it has been in operation. Generally, waiting 10 to 15 minutes is a reasonable time frame to adequately cool and drain the condensate from the system. Additionally, specifics may vary depending on equipment type and operating conditions. Be sure to follow your device manufacturer’s guidelines and recommendations to ensure safety and optimal performance.
