Description

NEWIN NWF series mixed flow closed circuit cooling tower/ Closed type cooling tower

NWF series mixed flow closed circuit cooling tower is available in capacity for single cell from 100 tons to 250 tons, various modular combinations of cooling towers are designed to meet different requirements. This cooling tower is highly used in heating, ventilation, air-conditioning, and light to medium processing applications.

Features

♦ Factory assembled, convenient transportation and installation
♦ Excellent heat exchange performance
♦ Easy maintenance without stop working
♦ Small cover area, low comprehensive investment
♦ Energy-saving and environment friendly

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.
