UACW series — Low temperature water chiller

Industrial water chillers are divided into two types: air-cooled and water-cooled, mainly referring to the different condensers. Technically, water cooling is 300 to 500 kcal/h higher than air cooling; In terms of price, water cooling is much lower than air cooling; In the installation, water cooling needs to be incorporated into the cooling tower before use, and air cooling is mobile without other assistance. However, air cooled water chiller relies on the fan to dissipate heat, which has requirements for the ambient environment: such as ventilation, humidity, air PH value and etc...

Remark:
1.The cooling capacity is based on the inlet water temperature of 7°C and outlet water temperature of 12°C, and ambient temperature is 30°C/35°C.
2.Working condition: Chilled water temperature range is from 5°C to 35°C; the difference between the inlet and outlet of chilled water temperature is from 3°C to 8°C, and ambient temperature is lower than 35°C.
