Proper daily maintenance and care of the cryostat are essential for users to understand and master. The following information is intended to provide useful guidance and practical advice for most users!
1. Before starting the air-cooled low-temperature thermostat unit, check if the fan is rotating in the correct direction. If it rotates forward, it is fine to start. If it rotates backward, this indicates a reversed power supply, and you should correct the wiring before proceeding.
2. The set values of all protection devices on the unit have been pre-adjusted by Ningbo Xinzhi Biotech. Users are advised not to change these settings without proper knowledge, as improper adjustments may lead to operational issues or damage to the equipment.
3. In case the unit triggers an alarm and stops, first press the stop button to turn off the alarm light. Then, investigate the cause of the fault. Never attempt to restart the unit until the issue has been resolved and verified.
4. Avoid turning off the unit by cutting the main power supply unless it's an emergency. If the unit will not be used for an extended period during winter, it’s recommended to shut down the system, disconnect the main power, and drain all water from the cooling loop to prevent freezing and damage.
5. Maintain a clean and well-ventilated environment for the equipment room. Regularly clean and maintain the condenser to ensure stable and efficient operation of the unit. A dirty condenser can significantly reduce performance and increase energy consumption.
6. For air-cooled cryostats, keep the surface of the low-temperature thermostat’s cooling coil clean. Ensure good airflow around the unit and regularly remove any scale or debris that may accumulate on the coils. This helps maintain optimal heat transfer efficiency. The Zhixin ZX series cryostats are specifically designed as air-cooled models.
7. If the cryostat has been in use for over six months, or if the high/low pressure switches frequently malfunction, or if the cooling capacity begins to decline, it’s time to schedule professional cleaning of the condenser. If the low-temperature thermostat continues to trigger long beep alarms despite multiple repairs, it is strongly recommended to contact a certified technician for further inspection and maintenance.
By following these guidelines, users can extend the lifespan of their cryostat, improve its performance, and avoid unnecessary downtime. Always refer to the user manual and consult with qualified personnel when in doubt.
