What is an Evaporative Condenser?
Designed for industrial refrigeration, industrial processes, and HVAC, HACST's evaporative condensers lower system condensing temperatures thereby reducing compressor horsepower, saving up to 15% energy compared to traditional air-cooled systems. This cost-effective cooling solution condenses refrigerant vapor in a coil that is continually sprayed with water. As the water evaporates, fans reject this heated vapor to the atmosphere.
Principle of Operation
The vapor to be condensed is circulated through a condensing coil, which is continually wetted on the outside by a recirculating water system. Air is pulled over the coil, causing a small portion of the recirculating water to evaporate. The evaporation removes heat from the vapor in the coil, causing it to condense.

HACST manufactures two types of evaporative condensers: combined flow and counterflow.
Combined Flow Configuration
Combined flow is the use of both a condensing coil and fill surface for heat transfer in an evaporative condenser. The addition of fill surface to the traditional evaporative condenser design reduces evaporation in the coil section, reducing the potential for scaling and fouling. HACST's combined flow evaporative condensers utilize parallel flow of air and spray water over the coil, and crossflow air/water flow through the fill surface. In parallel flow, air and water flow over the coil in the same direction. In the fill section of HACST's combined flow evaporative condensers, air and water interact in a crossflow configuration: water flows vertically down the fill as air flows horizontally across it.
Combined Flow Evaporative Condenser Advantages :
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 Evaporative condenser 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.
Counterflow Configuration
In a counterflow evaporative condenser design, the flow of the air is in the opposite direction of the spray water. In HACST's counterflow evaporative condensers, air travels vertically up through the unit while the spray water travels vertically down over the coil. The flow of air through most factory assembled evaporative condensers is provided by one or more mechanically driven fans.
Evaporative Condenser is widely used in energy chemical industry, Pharmaceuticals coal, electricity, industrial refrigeration, beer, beverage, food processing, the cold storage, the building air conditioning refrigeration, etc
