The closed refrigeration and heating circulators of different manufacturers have a certain life span. Reasonable and correct operation and maintenance of the closed refrigeration heating circulator can effectively extend the service life.

The user regularly maintains the closed refrigeration heating circulator, promptly eliminates the instrument failure, and makes maintenance records. The large equipment is cleaned and maintained 2-4 times per semester. The damaged closed refrigeration heating circulator should be overhauled by the equipment manufacturer’s professional. If external repair is required, the application should be submitted to the equipment. Equipment management personnel should strive to learn business and improve the level of management, maintenance and maintenance. Conduct regular inspections according to the specifications specified by the instrument or the performance indicators during commissioning, and register for future reference.

When the closed refrigeration heating circulator is turned on, it should be seen whether the steering of the fan is accurate. If the forward rotation can be started, the reverse rotation indicates that the power supply wiring is reversed, and the phase sequence must be replaced before starting. The setting values of each protection device are high and low temperature cycle. The factory has been set up, and users should not change it at will.

When the closed cooling and heating circulator is stopped, press the stop button to check the cause of the high fault. Do not force the machine to run before the fault is eliminated. If you use it for a long time in the winter, turn off the main power and drain the water in the system. It is necessary to keep the machine room clean and ventilated well, and carry out the cleaning and removing work of the condenser on schedule to ensure that the refrigeration and heating integrated machine does not work normally.

When using a closed refrigeration heating circulator, it is also necessary to pay attention to the selection of materials made of materials that are resistant to high temperature and corrosion resistant processes. In general, when using a closed refrigeration heating circulator, the temperature is in the range of 100 ° C – 300 ° C, the heating temperature is different, the oil used is also different, glycerin, paraffin oil, silicone oil, vacuum pump oil or some vegetable oil Yes, you can choose the right oil based on their heating temperature.

Closed refrigeration heating circulators provide corresponding cold sources in the pharmaceutical, chemical, biological and other industries. As a constant temperature source, the performance requirements are self-evident, so we must pay attention to the necessary maintenance.
