Important terminology: In many cooling tower applications, this type of component is more accurately described as a stainless steel heat exchanger coil, closed-circuit cooling tower coil, or cooling coil rather than an evaporator coil. The term “evaporator coil” is generally used when the coil is part of a refrigeration cycle. We can manufacture or supply the coil according to its actual operating application.

A stainless steel corrugated heat exchanger coil is a tube assembly designed to transfer heat between a circulating fluid and another cooling medium without directly mixing the two fluids.
The coil consists of multiple lengths of tubing arranged in parallel or series circuits. In the pictured configuration, corrugated tubes are formed into repeated coil sections and connected to upper and lower headers. The headers distribute the process fluid through the individual tube circuits.
During operation, hot process fluid passes through the stainless steel tubes while cooling water or another cooling medium removes heat from the outside of the tubes.
This arrangement is particularly useful in closed-circuit cooling towers, where the process fluid remains separated from the external cooling water.
One of the most important features of this cooling coil is its corrugated tube construction.
Unlike a completely smooth tube, a corrugated tube contains a specially formed surface profile. As fluid flows through the tube, the corrugation can disturb the boundary layer and increase turbulence.
This can provide several potential advantages:
Greater turbulence can improve heat transfer between the internal process fluid and the tube wall.
Improved heat transfer performance can help engineers achieve the required thermal duty within a relatively compact coil footprint.
The internal geometry promotes fluid movement and mixing, helping reduce stagnant areas inside the tube.
The corrugated geometry provides an enlarged effective heat-transfer surface compared with a simple straight smooth tube of similar nominal dimensions.
Actual performance depends on tube geometry, fluid properties, flow velocity, temperature difference, fouling conditions, and overall system design.
Stainless steel is widely selected for industrial heat exchanger coils because of its combination of strength, corrosion resistance, fabrication capability, and service durability.
304 stainless steel is commonly used for general industrial water and cooling applications where the operating environment is not highly aggressive.
It provides good corrosion resistance and is often a cost-effective material for general-purpose cooling coils.
316 stainless steel contains molybdenum and generally provides improved resistance to chloride-containing and more corrosive environments.
It can be considered for applications involving:
Higher chloride concentrations
Coastal environments
Aggressive process water
Chemical processing
Industrial water treatment
More demanding corrosion conditions
The appropriate stainless steel grade should always be selected according to the actual water chemistry and process-fluid composition.
This stainless steel coil can be used as the heat-transfer component in a closed circuit cooling tower.
In a closed-circuit system, the process fluid circulates inside the coil rather than flowing directly through the cooling tower fill.
The basic heat-transfer process is:
Hot process fluid enters the coil.
The fluid travels through the stainless steel corrugated tubes.
Heat passes through the tube wall.
Cooling water is distributed over the external coil surface.
Airflow removes heat from the cooling water.
Cooled process fluid exits the coil.
The cooled fluid returns to the industrial process.
This configuration helps isolate the process fluid from the cooling tower water circuit.
Our stainless steel corrugated cooling coils can be used in a wide range of industrial applications.
Used as heat-transfer coils in closed-circuit and evaporative cooling systems.
Suitable for industrial processes that require continuous removal of heat.
Can be incorporated into engineered heat-transfer equipment for HVAC and thermal management applications.
Stainless steel construction can provide enhanced resistance in appropriately selected chemical environments.
Where hygienic construction and corrosion resistance are required, suitable stainless steel grades may be specified.
Cooling coils can be used in auxiliary cooling systems and industrial heat-rejection equipment.
Engineered coil assemblies may be used in cooling systems requiring reliable liquid heat transfer.
The corrugated coil configuration can be incorporated into customized heat exchanger assemblies.
Stainless steel provides substantially better corrosion resistance than many conventional carbon-steel materials, particularly when the correct grade is selected for the operating environment.
A properly designed and maintained stainless steel coil can provide reliable service over an extended operating period.
Corrugated tubing promotes turbulence and provides a large effective heat-transfer surface.
The coil can be arranged in multiple rows to provide substantial heat-transfer capacity within a relatively compact installation area.
Customized headers and connection sizes allow the coil to be engineered for different piping configurations.
Coil length, width, height, tube arrangement, material, connection dimensions, and circuit configuration can be adapted to specific requirements.
The choice between corrugated and smooth tubing depends on the application.
| Feature | Corrugated Tube | Smooth Tube |
| Internal turbulence | Higher potential | Generally lower |
| Heat transfer | High potential | Conventional |
| Surface geometry | Corrugated | Smooth |
| Compact heat transfer | Excellent potential | Conventional |
| Pressure drop | May be higher | Usually lower |
| Cleaning considerations | Application dependent | Generally simpler |
| Customization | Available | Widely available |
Corrugated tubing is particularly attractive where high heat-transfer performance and compact equipment are priorities. However, pressure drop and fluid cleanliness must be considered during system design.
Every industrial cooling application has different thermal and mechanical requirements. We therefore support customized coil configurations.
Available customization may include:
Coil length
Coil width
Coil height
Tube diameter
Tube wall thickness
Corrugation geometry
Tube pitch
Number of tube rows
Number of circuits
Header size
Inlet connection
Outlet connection
Connection orientation
Stainless steel grade
Mounting frame
Overall coil capacity
Customers can provide a drawing, existing coil dimensions, photographs, equipment model, or operating parameters for engineering evaluation.
A damaged or fouled heat-transfer coil can reduce cooling capacity and increase operating costs.
Common signs that a cooling coil may require inspection or replacement include:
Reduced cooling capacity
Abnormal process-fluid temperature
Increased pressure drop
Tube leakage
Corrosion
Tube deformation
Header leakage
Excessive scaling
Severe fouling
Reduced water distribution over the coil
For replacement projects, the new coil should match the original equipment's thermal duty, dimensions, connection arrangement, pressure requirements, and fluid compatibility.
We can support OEM replacement and aftermarket cooling tower coil requirements based on available technical information.
Regular inspection is important for maintaining heat-transfer efficiency.
Cooling tower water can cause mineral deposits, biological growth, dirt, and scale on the external tube surface.
The coil should be inspected periodically and cleaned using a method appropriate for the stainless steel grade and fouling type.
The process-fluid circuit should be monitored for:
Pressure drop
Flow reduction
Temperature changes
Scaling
Corrosion
Leakage
If internal fouling becomes severe, professional cleaning may be required.
Proper cooling tower water treatment can reduce scale formation, corrosion, and biological contamination.
Water chemistry should be controlled according to the cooling tower manufacturer's recommendations and the coil material specification.
Before ordering a replacement or custom coil, provide as much information as possible.
Specify the required heat-transfer capacity, such as kW, kcal/h, or BTU/h.
Identify the fluid circulating inside the coil.
Provide process-fluid entering and leaving temperatures.
The required fluid flow rate is essential for thermal and pressure-drop calculations.
Specify normal and maximum operating pressure.
Cooling water chemistry, chloride concentration, pH, hardness, and other relevant factors can influence material selection.
Provide the maximum permitted coil dimensions.
Specify connection diameter, connection type, and connection orientation.
Select 304, 316, or another suitable material according to the application.
