In daily production, we will encounter the cold dryer can not start, what is the problem? In fact, the cold dryer can not start for many reasons, we need to analyze and solve according to different situations, the following steps to solve it one by one!

1, insufficient or too much refrigerant, please fill the leak and vacuum, add enough refrigerant or release excess refrigerant.

2, the four-way valve internal leakage, constitute misoperation, confirm the damage after the update.

3, condenser ventilation is poor or air short circuit, please remove the outdoor obstacles, clean the condenser.

4, the capillary assembly (including filter) is blocked, the suction temperature rises, please replace the capillary assembly.

5, the protection relay itself is faulty, please use a multimeter to check whether the contact is on when the air compressor is not hot, if not, replace the new protector. When replacing the air compressor, check the starting capacitor and the starting relay (if one of them is damaged, both must be replaced).

Water-cooled freeze dryer

6, the air compressor itself is faulty, such as short circuit, open circuit, shell through the ground, etc., check and confirm the replacement of the air compressor.

7, high pressure pressure is too high, pressure relay action, please analyze the reason, according to the situation to be excluded.

8, the system is mixed with non-condensing liquid gas (such as air, etc.), please vacuum and reperfusion.

9, the air compressor running current is too large, please find out the reason to be excluded.

10, outdoor unit ambient temperature is too high, please leave the heat source, avoid the sun.
