Product Description

Closed Circuit Evaporative Condenser
1-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.
2-Convenient Maintenance
Huge maintenance space makes it convenient to inspect the product. Technicians can enter the cooling tower during operation time.
3-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.
4-Slope Water Basin Design
Suspended PVC fill and sloped water basin floor toward the drain facilitate cleaning
Counter Flow Evaporative Condenser
1-No infill designed, more compact structure, lower profile, less installation area required,and easy for transport and installation.
2-Suitable to severe environment as its structure much more close, which couldvprevent from sand and dust. So it widely used for casting workshop,mining factory etc.
3-Suitable to high temperature fluid, because hot spraying water will not distort pvC fill as no pvC fill designed.
4-Freezing resistance,because there is no PVC fill to slow down spraying water flow speed.

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.
3-What is your Minimum Order Quantity(MOQ)?
MOQ is 1set. Because our business for both wholesale and retail clients.
4-How do I get repair parts and how long does it take?
