✅Diverse Air Intake Modes:You can choose either single-sided air intake or double-sided air intake to meet the diverse needs of projects.

✅Suitable for Multiple Scenarios:Suitable for projects with high requirements for operation and maintenance efficiency, such as central air conditioning, industrial equipment, and rail transit.


JCN Series Counterflow Closed Cooling Tower

Closed - loop circulation | No worries about water quality

✅ No worries about water quality: The closed - loop circulation design completely avoids medium pollution and scaling, and extends the equipment service life by 30%.

✅ Anti - freezing and energy - saving: Automatically switches to the dry - cooling mode in winter without electric heating, significantly reducing winter energy consumption.

✅ Strong corrosion resistance: The cooling coil is treated with double - sided anti - corrosion, suitable for high - purity water and high - cleanliness cooling requirements.

✅ Industrial adaptation: The first choice for scenarios with strict water quality requirements such as steel, photovoltaics, and lithium batteries.


JAC series dry and wetCombined cooling tower

Water - saving pioneer | Ultra - clean emissionDischarge

✅ Extreme water saving: The combined design of the dry section and the wet section enables an annual water - saving rate of over 40%.

✅ Ultra - clean emission: Three - stage high - efficiency water collectors with an extremely low drift rate meet the strictest environmental protection requirements.

✅ White smoke elimination technology: The dry section heat exchange eliminates the white fog generated by the wet - cooling section, avoiding visual pollution and impacts on the surrounding environment.

✅ Reliable anti - freezing: It operates in the dry - cooling mode in winter and can prevent freezing without electric heating.

✅ Environmental protection adaptation: It is the first choice for water - scarce areas and projects with high environmental protection standards such as thermal power and chemical engineering.
