Warm (wet) chamber maintenance and repair tips
1. Since the temperature (wet) chamber is typically a high-value piece of equipment, it's important to place it in a stable and controlled environment. Our recommended operating temperature range is between 8°C and 23°C. If your laboratory doesn't have this condition, you should install an appropriate air conditioner (air-cooled) or cooling tower (water-cooled) to maintain the required environmental stability.
2. Ensure professional management and oversight. If possible, send designated personnel to the manufacturer’s facility for specialized training. This will help them gain deeper knowledge and practical experience in maintaining and repairing the equipment effectively.
3. Regularly clean the condenser every three months. For air-cooled systems, check and maintain the condenser fan, and remove any dirt or debris from the condenser to ensure efficient airflow and heat dissipation. In water-cooled systems, make sure the inlet pressure and temperature are within acceptable ranges, and maintain proper flow rates. Clean and descale the internal parts of the condenser regularly to sustain its performance.
4. Clean the evaporator (dehumidifier) periodically, ideally every three months. Due to varying sample cleanliness, dust and small particles can accumulate under forced air circulation. Regular cleaning helps maintain efficiency and prevents buildup that could affect performance.
5. Clean and calibrate the circulating fan and condenser fan. These components can collect dust and other particles over time, especially in different working environments. Routine cleaning ensures smooth operation and prolongs their lifespan.
6. Keep the water lines and humidifier clean. Clogged waterways or dirty humidifiers may cause the humidifier to dry out, leading to damage. Regular cleaning and maintenance prevent such issues and ensure consistent humidity control.
7. After each test, set the temperature close to ambient conditions and let the system run for about 30 minutes before turning it off. Then, wipe down the interior walls of the working chamber to remove any moisture or residue.
8. If the equipment needs to be moved, always do so under the guidance of our technical staff. This prevents accidental damage and ensures safe handling during transportation.
9. If the equipment is not used for an extended period, power it on at least once every two weeks for a minimum of one hour. This helps maintain internal components and prevents long-term degradation.
10. Follow a systematic approach when troubleshooting. Since environmental test chambers consist of multiple integrated systems—electrical, refrigeration, and mechanical—any issue should be analyzed thoroughly. Start by checking external factors like cooling water supply and power source. Once these are ruled out, systematically break down the system to identify the root cause. Use the reverse engineering method: first check the electrical wiring diagram, then inspect the refrigeration system. Avoid disassembling or replacing parts without understanding the problem, as this can lead to further complications.
By following these maintenance and repair guidelines, you can significantly extend the life of your warm (wet) chamber and ensure reliable, accurate performance during testing.
