| Liquid Medium | Pure water (or distilled water) + special corrosion inhibitor or antifreeze (select the ratio according to the freezing Point) |
| Liquid Flow, L/min | Pure Water ≥ 10.2L/min for pure water; if the antifreeze needs to be changed, the flow rate needs to be increased, such as 30% ethylene glycol aqueous solution antifreeze requiring ≥11L/min. *Remarks:10.2L/min corresponds to the temperature difference between inlet and outlet water close to 10.5°C at normal mode. |
