Mixed Flow Closed Cooling Tower NWF/ Close-loop system cooling tower
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.
Components Instruction
AXIAL FLOW FAN
Uses cooling tower special aluminum alloy axial flow fan,forward type blade structure design, small wind resistance, big air volume, low noise, good performance, high efficiency. Streamline high strength fan stack gurantees airflow uniform through the fan inlet and outlet area, maximum reduce the energy comsuption. Fan motor's protection class: IP55, Insulation class: F class.
COOLING COIL
Cooling coils as the core parts of the closed cooling tower, are made up of great quality copper coil or steel coil. Coil inside is through cooling medium, outside is cooled by water spray to meet the cooling requirement.
Steel coils (G type) are used by high-quality Ф19 mm seamless fluid tube, and processed by stainless steel 304 to enhance the coil pipe anti-corrosion ability, extend service life.
Copper coils (T type) are used by T2 deoxidized acid copper tube, the silver electrode is used to connect between the copper pipe and elbow welding, low solder joint and good quality, design pressure is 1.2MPa.
SPRAY PUMP
Used great mechanical seal to prevent from the leakage, made by the dedicated outdoor motor, and special configuration imported bearings, to ensure that the fan, water pump has long term reliable operation, low power, large flow, low noise, excellent performance, etc. The pump body is precision casting, strong and long service life.
DRIFT ELIMINATOR
Original detachable eliminator adopts good performance PVC material, its special structure could change the airflow direction, effectively remove from the wet air moisture in the air, released the drift loss below 0.001%, maximum save the water, what's more, to make sure the area around cooling tower no pollution, and prevent from the germs spreading.
HIGH-EFFICIENCY FILM FILLS
Hanging film type fill spreads the water into a thin film, flowing over large vertical surfaces, promoting maximum exposure to airflow. It incorporates highly efficient cellular eliminators and louvers, integrally molded within the fill sheets, preventing water from escaping and assuring precise air distribution throughout wide variations in airflow. Unlike towers equipped with separate external louvers, this fill operates virtually icefree even in extremely cold weather.
ADVANCED WATER DISTRIBUTION SYSTEM
The spray system uses in a variety of high flow rate and anti-clogging basket type nozzles, to ensure continuous uniform water spraying on the surface of the coil. With the help of induced air, water can cover all the coils to the utmost extent to do the complete heat exchange among water, air, and refrigerant. In this case, heat transfer efficiency will increase dramatically. The nozzle is connected on the spray pipe branch. When cleaning, the nozzles and spray pipe branch can be easily dismounted.
