NWN-Eco Series EC fan drive energy saving closed cooling tower
NWN-Eco series Eco type Closed Cooling Tower is a type of closed circuit cooling tower designed with Green Technology EC fan drive system. Higher efficient and Higher energy saving. Specially suit for the place which is space limited.
EC Fan Drive System
EC FAN
Using EC fan, through static and dynamic test of production process, to meet the cooler heat transfer performance under the premise of maximum noise reduction; harmonics are kept below 35% with PFC and maintain high static efficiency even at low speeds.
DRIVE
Using directly shaft transmission. Smooth running, low noise, fan bearing with conical roller bearing, large carrying capacity, long life, rated life over 20,000 hours.
EC MOTOR
Using closed cooling tower dedicated EC motor, IP55 protection grade, insulation class is F, suitable for hot and humid environment to run for a long time. EC motors can achieve energy efficiency above IE4. Products comply with IEC international standards, with high efficiency , low noise, long life, reliable operation, etc.
Forced Draft Hybrid Wet Dry Closed Type Cooling Tower
NCFN series Forced Draft Dry-Wet Cooling Tower is a type of closed circuit cooling tower designed to special application in desert area where lacking of water, and temperature is extraordinary hot in summer but cold in winter season and which place with poor ventilation.
This type of cooling tower can save water and energy in cold season and ensure enough cooling capacity in hot season.
Features
-Forced draft system, suif for the
place with poor ventilation.
-Hybrid design, Dry-Wet operation mode.
-Save energy during cold season.
-Anti-freezen, High performancein during hot season.
-Closed circuit design ensures high water quality.
Hybrid Wet Dry
Dry Cooling Mode
When temperature is lower than a certain temperature(-10ºC), or output temperature lower than a setted temperature,
the spray pump stop working. cooling tower working under dry cooling mode. No evaprating loss, save waterand energy.
Wet Cooling Mode
When temperature is higher than a certain temperature(-2ºC), or output temperature higher than a setted temperature,
the spray pump sart working. cooling tower working under wet cooling mode. Evaporative cooling ensures big cooling capacity.
The advantages of closed cooling tower compared to other cooling towers:
Compared with the open type cooling tower:
Contains no pollutants of closed cooling can significantly reduce the scaling phenomenon in the process engineering,
To ensure the constant process performance in the long service term
Compared with the disposable water system:
Reduce the adverse impact on the environment, save 95% of the cooling water
Lower installation costs, reduce the space:
- To integrate the function of the effective cooling tower and heat exchanger and a single device, reduces the complexity of the tube and filling water system.
- Closed cooling tower to make room for equipment installation valuable space.
- Reduce the size of process conforms to the required pumps and pipes.
Combined-flow Closed Circuit Cooling Tower (mixed-flow)
Energy efficiency
Axial fan uses half the energy of similar centrifugal fan units.
High performance fill factory-configured for excellent water or air contact and minimal air pressure drop. Guarantees optimal cooling tower efficiency.
Low maintenance and easy inspection
Inspect and maintain safely towers with unrivaled comfort, while standing inside.
- The cooling tower has a internal area and easy inspection and maintenance access, access via large hinged door to optional internal walkway: No basin draining needed for unit interior inspection.
- Inspection of water distribution system (spray branches and nozzles) possible outside the unit, during operation.
- Easy to inspect the coil during operation from the outside or from the inside via the removable drift eliminator modules.
- Easy to inspect the fill from the inside and via the removable combined inlet shields from the outside.
Easy installation
Cooling towers are factory-built and shipped in sections for larger models to reduce the overall size and weight, allowing easy on-site section assembly with smaller crane.
Counter Flow Closed Circuit Cooling Tower
More precise control of energy
As its fill packing design, there are more space of cooling coil, suggest to select dul-speed motor to achieve more precise control of energy.
Compact structure, smaller installation area
The cooling tower Integrated traditional condenser, cooling tower, circulating water pump, pool and connection pipe. It can operation without above auxiliary equipment, saved lots of space and has the lower comprehensive investment advantage
Compact installation of auxiliary equipment.
For some small cooling tower project, we put the small counter flow closed cooling tower and circulating pump, circulating water tank and control system together, formed a model of a whole unit, convenience for the users of the product.
