Product Description
Designed for Industrial refrigeration, industrial processes, and HVAC, Heleng’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.
Combined Flow Configuration
Heleng manufactures two types of evaporative condensers: combined flow and counterflow. 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. Heleng’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 Heleng’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.

Materials of Construction
Determining the appropriate material of construction for a project depends on several factors, including water quality, climate and environmental conditions, availability of time and manpower for maintenance, unit lifetime requirements, and budget. HELENG provides the widest variety of material of construction options in the industry and has the ability to provide a solution to meet all conditions and budgets.

Maintaining the Mechanical Integrity of Evaporative Condensers
Evaporative condensers are an efficient and cost-effective heat rejection solution for various applications—food and beverage refrigeration, industrial machinery cooling, and HVAC. The units work by condensing superheated refrigerant vapor inside a coil that is continually sprayed with water. As the water evaporates, fans reject the heated water vapor to the atmosphere. By lowering system condensing temperatures, evaporative condensers reduce compressor horsepower requirements, resulting in energy savings of up to 15% when compared to air-cooled systems.
A comprehensive program of routine preventive maintenance will keep refrigeration systems performing at peak efficiency, maximize system operating life, and reduce unplanned downtime due to equipment failure. It also helps to ensure reliable and safe operation, which is critically important to avoid leakage of ammonia and other refrigerants. Regular inspections are, of course, key and should be done in accordance with the manufacturer’s recommendations and plant preventative maintenance schedule. Below are general guidelines for the areas of inspection that should be part of any effective evaporative condenser preventive maintenance program. These guidelines cover inspections in 10 areas. Although maintenance frequency will depend on a variety of factors—e.g., condition of circulating water, cleanliness of ambient air, and the unit’s operating environment—each area of inspection should be performed at least annually and more frequently as recommended by the manufacturer for a particular component or as circumstances warrant.
For each inspection, it is important to document the inspection process and all findings, the date of the inspection, the name of the person performing the inspection, any actions taken. If any additional future actions or repairs are necessary perform per manufactures recommendations or industry standards. Digital images are a useful method for documenting present conditions and demonstrating changes over time.
To ensure worker safety, all proper lock out-tag out procedures for the unit and any site safety procedures must be followed prior to beginning inspection or maintenance work. Additionally, measures must be taken to confirm there is no refrigerant left in the coil. This is usually done by employing a vacuum system prior to entering or servicing the condenser. Always follow industry best practices regarding the use of proper PPE and “one in-one out” procedures.
| Recommended Inspection Tools
Most people carry a smartphone with a good digital camera, which is a useful tool for photographing or recording inspection findings. Other recommended tools include an infrared thermometer, an infrared camera, an ultrasonic metal thickness meter, a vibration meter (ultrasonic or accelerometer), a laser alignment tool, a multimeter for voltage and amperage, a micrometer depth gauge, and a dye penetrant test kit to detect cracks. Importantly, a complete inspection kit will also include the manufacturer’s installation, operation, and maintenance manuals and lock-out / tag out forms.
