This series has two unit modules to choose from. Unit 65 has two completely independent refrigeration systems per unit module, while Unit 130 has four completely independent refrigeration systems per unit module. By combining 1-16 identical or different unit modules, a series of products with cooling capacity ranging from 65 to 1040kW can be formed. 65 units can combine up to 16 unit modules, and 130 units can combine up to 8 unit modules. The B1 series variable frequency modular air-cooled cooling (heating) water unit is widely used in air conditioning projects of various sizes in newly built and renovated industrial and civil buildings. For projects that have high requirements for noise and surrounding environment, and are inconvenient to install cooling towers, modular air-cooled cooling (heating) water units are your ideal choice.
