Water Cooled Chiller (Scroll Compressor)
R22: 35÷480kW
Features of Water Cooled Chiller (Scroll Compressor)
1. This water cooled chiller equipped with brand hermetic scroll compressor is among the classic cooling machines our company has developed;
2. We can provide customized commercial air cooled chilling units of this model whose heat recovery rate could be 30%, 50% or 100% according to our customers' specific requirements;
3. This scroll type cooling equipment enjoys a relatively wide range of cooling capacity from 35kW to 480kW;
4. Of a laconic structure, this water cooled chiller adopts a highly efficient shell and tube heat exchanger, requiring much smaller space;
5. The commercial chiller water temperature could be adjusted from 5 ℃~15 ℃, enabling the unit to satisfy different cooling demands year around;
6. This multifunctional chiller is designed with several effective protective devices such as those for extremely high/low pressure, overheat, oil temp, lack-phase and overload of compressor, this water cooled chiller is safe to operate.
