Metal Closed Cooling Tower Axial Induced Fan Motors Assembly with Siemens Motors
The Cooling Tower Axial Induced Fan Motors Assembly works by pulling air through the cooling tower and expelling it into the atmosphere. The axial induced fan motors are connected to the fan blades, which rotate and create a negative pressure inside the cooling tower. This negative pressure draws hot water vapor from the tower, allowing for evaporation and cooling of the water. The cooled water then circulates back into the system for further cooling.
The advantages of Cooling Tower Axial Induced Fan Motors Assembly include:
1. Efficient cooling: The induced fan motors provide a consistent airflow, promoting efficient cooling of the water in the tower.
2. Energy savings: By efficiently cooling the water, the cooling tower assembly helps save energy by reducing the need for additional cooling processes.
3. Space-saving design: The axial induced fan motors are compactly designed, saving space in the cooling tower system.
4. Low maintenance: The assembly is designed for durability and reliability, requiring minimal maintenance over time.
5. Environmentally friendly: The cooling tower assembly promotes water conservation by efficiently cooling and recycling water in the system.

02 Working principle
For BNX counterflow closed cooling tower, the fresh air intakes from bottom air inlet and mixes alternate with the falling spray water in reverse direction, and will be formed saturated hot air. The heat will be exhausted out by top fans, but the water will be collected to water collection basin for secondary spraying by its special designed drift eliminator. As no infill inside, BNX counterflow closed cooling tower has much space to enlarge its discharge area per unit heat of the coil, more compact structure and requires less footprint.

Fans rigorous static and dynamic balance need to be corrected before delivery, no chattering.
F. Duct connection with fasteners made of galvanized steel or stainless steel;
G. Direct-drive type fan, no need belt transmission, to save energy and improve drive efficiency, so the fan with following advantages: simple layout, low noise, no transmission loss, high efficiency, low friction components, easy maintenance etc.
2. Coils: Galvanized steel, stainless steel..
A. Each group of coil tubes is arranged with consistent slope, and the slope direction same with the water flow direction, east to facilitate water discharge from the pipe.
B. Bracket for the coil is made by welded sectional material, and all processing technologies meet China National Metal Welding Workmanship Requirements & Standard. The cleaning and coating workmanship of the coil bracket surface same to the evaporative condenser bracket.
C. Designed pressure is 2.0MPa, tubes in each group go through previewing and pressure test, and then to be assembled after getting through quality test. Test in the water with pressure 2.5MPa after assembled, to ensure its high performance in pressure resistance.
D. Heat exchange coil is made of Galvanized steel or stainless steel.
3.Spray water distribution system
A. Spraying Pumps: The spraying pump special designed for evaporative condenser, with Siemens or WEG brand motors. With high flow, low head, high efficiency, low noise, low power and energy saving advance. Pump motor with protection class IP55, insulation class F.
B. Spraying Water Pipe: made of PVC, with flowing advantages: easy cold, high pressure resistance, anti-corrosion, and water resistant. All spraying manifolds are adopted removable type, easy to replace and clean.
C. Nozzle: ABS material injection molding nozzle basket type -2-efficiency provided by the well-known brand suppliers; Adopt bigger hole diameter nozzles to prevent from blocking, which has a large flow, no clogging, water distribution uniformity, etc; in the design of the nozzle so that the different positions of the cloth water flow deviation <5% of the entire water distribution system can guarantee 70% to 130% of the rated flow of water distribution uniformity.
E. Water level control system: the water level in spraying water tray is controlled by galvanized steel ball valve.
4.Fill &Drift Eliminator
A. The fill is one of the most important part of cooling tower, PVC heating exchange layer more effective to cool the water temperature by enlarge the evaporating surface.
B. The PVC fill are produced by total automatic controlled high-speed blister forming machine in my workshop, better and more quick shaping. Meanwhile, the machine ensures the consistency of all fillers, being glued to entire body with glue rate no less than 95%, the compressive strength ≥300Kg/m2. The fillers have large heat exchanging surface and minimum air resistance, more effective.
C. With special design, fill surface has good hydrophilicity, water absorptivity less than 0.015%. So more water film produced without splashing down. Water flowing rate less than 0.01%, more water saving, very suitable to Water stress region. Corrosion resistant, flame retardant, reinforced PVC packing, inflaming retarding oxygen index≥30.

09 FAQ
(1)Your company is a manufacture or trading company?
We are a leading cooling tower manufacturer with 38 years producing experience. The famous brand-"Heng An" is well known not only China but all over the world. The company is a large group company loacted in Weifang Citey of China.
(2) What is the difference between a "counter flow" and a "cross flow" cooling tower?
The crossflow or counterflow designation characterizes the orientation of the airflow within the heat-transfer media (fill) in the tower with respect to the direction of water flow.
In counterflow towers air travels vertically upwards through the fill and makes intimate contact with water droplets falling down through the fill media. Hence the air and water travel in opposite directions.
In crossflow cooling towers the air passes through the fill media in a horizontal direction, thus crossing the downward water flow. Counterflow towers are inherently more efficient than crossflow towers.
