Spring Festival Shutdown | Maintenance Key Points -Environmental Simulation Equipment

As the Spring Festival approaches, high-precision environmental simulation equipment may face risks such as restart difficulties and performance fluctuations during the holiday period without professional maintenance. Sanwood Technology provides Professional shutdown maintenance solutions to ensure smooth equipment restart, extend service life, safeguard the accuracy and consistency of test data, and maintain year-round R&D and quality control progress.

Pre-Holiday Preparations

1.Thorough Cleaning and Inspection

Thoroughly clean the equipment before shutdown, especially the test chamber's inner chamber (high-temperature baking), condenser, evaporator and humidification system.

Also check the integrity of the door gasket to ensure sealing performance.

Check that all sensors are functioning properly and that the calibration data is within the valid period.

2. System Drainage and Frost Protection

For environmental test chambers equipped with humidification systems (such as constant temperature and humidity chambers), thoroughly drain all water from tanks and pipework to prevent freezing and potential pipe rupture during the low temperatures of the Spring Festival period.

Following drainage, it is advisable to dry the pipes using compressed air to prevent residual moisture from causing corrosion.

3.Power-off Protection and Environmental Control

Power Failure Protection: It is advisable to completely disconnect the equipment's power supply to eliminate electrical safety hazards during unattended periods over the Spring Festival. Simultaneously, unplug unnecessary cables and implement dust protection measures.

Environmental Control: Ensure the storage environment remains dry and well-ventilated, with temperatures maintained between 5-35°C to prevent damage to components from extreme temperatures.

Restart after holiday

Do not start the equipment at full load right after resuming work post-Spring Festival. Power on to check the control system first, then start each subsystem step by step. For compressor-equipped equipment, observe the compressor start interval and avoid frequent short-time restarts.

System Preheating: After powering on, allow the equipment to run unloaded for 2-4 hours to enable all systems to gradually reach normal operating conditions. Monitor operational parameters for stability during this period, noting any abnormal noises or alarms.

Performance Validation: Once preheating is complete, conduct basic performance validation tests. Run a standard test programme to verify that temperature and humidity control accuracy and stability meet requirements, ensuring equipment performance remains unaffected by the shutdown.

Conclusion

Professional shutdown maintenance is a key component of the laboratory quality management system.Through systematic Spring Festival shutdown maintenance measures, we not only ensure environmental simulation testing equipment—including Constant Temperature Humidity Test Chambers,Rapid-Rate Temperature Change Chambers, and High and Low Temperature Chambers —Rapidly resumes optimal operational status post-holiday, but also enhance equipment reliability, laying a solid foundation for year-round scientific research and testing activities.

As the Spring Festival approaches, make equipment maintenance plans in advance to ensure your professional equipment can "spend the holiday" with peace of mind. After the festival, it will be put back into operation in optimal condition, safeguarding the continuity and accuracy of R&D and testing work.
