ZOZEN after-sales service responds within 2 hours to solve the boiler problem caused by the low temperature

In the extremely cold whether, ZOZEN after-sales service department manager Liu was very worried about the boilers whether could be protected from the cold. He required all the on-site service personnel to inform our ZOZEN users of the freeze-proofing measures in order to protect the boiler and accessories from the cold damages.

On the last day of 2020, ZOZEN still received a call from our user in Suzhou that boiler accessories were damaged due to the low temperature. However, ZOZEN could not know the specific boiler operating situation via the telephone communication. Therefore, on one hand, ZOZEN instructed the user on emergency measures; on the other hand, ZOZEN immediately dispatched the after-sales technicians to the site.

The boiler accessories were frozen and leaking

During the cold wave, the temperature in Wujiang District of Suzhou was as low as -6 ℃. The environment temperature was too low and our user did not close the doors and windows of the gas-fired boiler room in time, which caused that the water level differential pressure transmitter was frozen and the three valves groups leaked, which finally resulted in the incorrect water level value. The boiler could not be shut down immediately for inspection and maintenance due to the steam demands, so ZOZEN technicians reset the value of boiler water supply to make the boiler system could be used temporarily and advised that the damaged boiler accessories should be replaced in time during the next shutdown period.

ZOZEN reminds boiler users that under low-temperature conditions, boiler operators must pay attention to the environment temperature changes and the influence on the boiler equipment. Especially, when it is below zero or snowing, the doors and windows of the boiler room should be closed and the open-air boiler system can take thermal insulation measures. It is also should be noticed that boiler accessories like the water level differential pressure transmitter are easily damaged in cold whether.

If the boiler needs to be shut down at night, the boiler operator must completely drain the water in the boiler, instruments and pipelines to protect the boiler parts from the damage caused by the freezing and expanding of remained water. What's more, during the freeze-proofing period, the forced draft fan, induced draft fan and circulating pump should keep working to ensure the operation of the oil system. All the electrically operated door and adjusting door should be powered off without any operation. After the boiler is started, it is first to manually test the flexibility of each door before the power is on to avoid damaging the electric head and affecting the boiler start.
