Closed circuit cooling tower provides many operational and maintenance benefits to the user by keeping the process fluid in
a clean, closed loop.
Protect process fluids from contamination
Maximize system efficiency by reducing fouling and scaling tendencies
Reduce system energy costs
Reduce system maintenance costs
Product Characteristics:
Excellent Heat Exchange Performance
Parallel air and water path as well as the combination of coils and PVC fill, this effectively avoid the dry spot and scale formation,
and improve the heat exchange performance.
Convenient Maintenance
Huge maintenance space makes it convenient to inspect the product.Technicians can enter cooling tower during operation time.
Convenient Transportation and Installation
The cooling tower is designed to be standard upper body part and bottom body part, making it is able to be shipped separately
and saves transportation and installation cost.
Slope Water Basin Design
Suspended PVC fill and sloped water basin floor toward the drain facilitate cleaning.
BHX Combined Flow Closed Circuit Cooling Tower Principle of Operation.
The process fluid to be cooled is circulated within a serpentine cooling coil, which is continually wetted on the outside by the
spraying water system. The heat is transferred by the wall of coil, becomes saturated steam when it meets spray water and air.
Then the heat will be discharged into atmosphere by fan, but water will be collected in the basin by drift eliminator for
recirculated spraying. The temperature of spraying water is reduced by PVC fill. spraying water flows in the same direction as
the fresh air, to cool coil mainly by significant heat conduction way, which is especially suitable to the cases when cooling
tower outlet temperature is much closer to the wet bulb temperature.

Who We Are
Shipment Procdures
Projects
1 Q: Is your company a manufacture or a trading company?
A: We are a leading cooling tower manufacturer and trading combo with more than 40 years producing experience since 1975.
The famous brand-"Heng An" is well known not only China but all over the world.
As a group company loacted in Weifang Citey of China, we have more than 1000 employees, area of 34hectares and total assets of USD 160 million.
2 Q: What is the difference between a "counter flow" and a "cross flow" cooling tower?
A: The cross flow or counter flow designation characterizes the orientation of the airflow within the heat-transer medium (fill) in the tower with respect to the direction of water flow. In counter flow towers air travels vertically upwards through the fill and makes intimate contact with water droplets falling down through the fill. Hence the air and water travel in opposite directions.
In cross flow cooling tower, the air passes through the fill medium in a horizontal direction, thus crossing the downward water flow.
At same situation, counter flow tower are inherently more efficient than cross flow tower.
3 Q: How do you get repair parts and how long does it take?
A: We have workshop and backup store supplying all parts. 90% of spare parts can be distributed to any plae on the world within one week.
4 Q: What if you don't have the professional engineers to install or maintain the tower?
A: We could dispatch experienced engineer on site to install the towers and train your staff for tower operation and maintaince.
5 Q: How can I choose a suitable cooling tower?
A: If you are available to provide the following information, we can help you to choose the suitable cooling tower.
| Application | Which industry or system using for? For example, HAVC system, casting cooling system |
| Water flow capacity | How many tons of water treatment per hour? |
| Inlet water temp. | Tempreture of hot water to be cooled |
| Outlet water temp. | Tempreture of cooled water, usually it would be at least 3-4 ºC higher than the bulb tempreture. |
| Wet bulb temp. | Highest wet bulb temp. of the location/area or city to install the tower is essential to know to evaluate the size of towers. |
| Power supply | The standard is 380V/3 phases and we have stock. But for customization, the delivery time would be longer. |
