Repair of a temperature and humidity test chamber in Hanoi
In early November 2025, HUST carried out the repair of a temperature and humidity test chamber (climatic chamber) for a customer in Hanoi. After receiving the information, HUST Vietnam’s technical team promptly arrived on site to inspect and resolve the issue.
During the initial assessment, we found that the chamber’s refrigeration compressor had weakened and was no longer able to provide sufficient capacity for the system. As a result, the temperature could not reach the required setpoint, the humidity fluctuated, the temperature–humidity chamber operated unstably, and the temperature recovery time was prolonged.
Based on the identified root cause, HUST Vietnam’s technical team replaced the compressor with a new unit matching the correct technical specifications and carried out related works to restore the equipment to optimal operating condition.
After completion, HUST inspected and test-ran the equipment under high-temperature, low-temperature, and high-humidity modes.
Results:
Temperature reached the setpoint quickly and remained stable
Humidity operated accurately according to the set values
The customer was fully satisfied with HUST Vietnam’s service
