ADVANTAGE
Dry-Wet Hybrid Cooling Mode
NCFN-GS cooling tower has the capability to adapt its operational modes in response to fluctuations in ambient temperature.Dry Cooling Mode
When the temperature falls below -10℃ or the output temperature is lower than the set point, the spray pump will cease operation and the cooling tower will switch to dry cooling mode. This minimizes water evaporation during cold seasons and provides ice water in certain working conditions as an alternative to refrigeration, resulting in water and energy savings.
Wet Cooling Mode
When the temperature exceeds a specific threshold (-2℃), or when the output temperature surpasses a predetermined level, the spray pump initiates operation, causing the cooling tower to function in wet cooling mode. Evaporative cooling guarantees substantial cooling capacity.
Water saving, Energy conservation, Environmental protection
> In comparison to conventional wet cooling towers, it has the capability to diminish the utilization of spray water and decrease overall water consumption.
> By implementing intelligent control systems and advanced cooling technology, energy consumption reduction and energy utilization improvement could be achieved, resulting in significant electricity savings.
> Dry-wet hybrid cooling effectively minimize water mist emissions, resulting in a reduced environmental impact and enhanced eco-friendliness.
Operation& Maintenance Cost Saving
> The closed-circuit circulation system guarantees the purity of the cooling medium, minimizes water contamination, and decreases water treatment expenses. Furthermore, dry cooling mode is utilized during winter to significantly reduce the risk of freezing for cooling tower components. This not only lowers equipment operation and maintenance costs but also ensures the long-term stable operation of equipment.
> The product is factory assembly, transported and installed conveniently, ultimately saving valuable time and effort.
