Does the Air Cooler Water Pump require antifreeze?

Air Cooler Water Pump Antifreeze Usage: Assessment and Recommendations

Whether antifreeze is needed mainly depends on the pump's installation environment and local climate conditions.

1. Assessment based on installation environment

Normal temperature environment: If the pump is installed inside a workshop or in a region with a mild climate, antifreeze is usually not needed; ordinary tap water or circulating water will suffice.
Low-temperature environment: If the pump is installed outdoors or in an area where the temperature is below 0℃, Cixi Xinhao Motor Co., Ltd. strongly recommends adding antifreeze to prevent freezing inside the pump, which could lead to pipe blockage or pump damage.

2. Antifreeze selection

It is recommended to use a special coolant with anti-rust and anti-corrosion additives. Long-term use of ordinary water may cause rust in the pump body due to corrosion, which will affect the pump's water pumping capacity and lifespan.
