In order to effectively prevent the chiller from being shut down for a long time during machine commissioning or from being damaged by ice due to the temperature difference between the north and the south during transportation, this letter is specially sent to inform the chiller of the winter drainage anti-freezing method, hoping that all enterprises attach great importance to it so as not to cause unnecessary losses.

1. The circulating coolant inside the chiller can be appropriately added with antifreeze (glycol solution) according to the local temperature.

2. If the shutdown time of the chiller is too long, the water in the water tank of the chiller must be drained clean to avoid ice damage to the machine due to too long shutdown.

3. Due to temperature differences, customers in cold areas who have just received unused machines are advised to first heat water into the boot cycle, and then add appropriate amount of antifreeze.

4. Due to the corrosiveness of antifreeze, the antifreeze and water are exchanged in a certain proportion and then added, using low concentration antifreeze;

Please inform your company's technical, operator, debugging personnel or end-use customers of the above content, if there is any confusion, please contact our relevant business personnel.

Sincerely look forward to communicating with you and learning from each other.
