Dry Ice Blasting for Safe & Effective Fin Fan Tube Cleaning

Power plant at twilight

Fin fan tubes are essential equipment for power plants, petrochemical plants and oil refineries, but they pose a challenge when it comes to keeping them clean and operating at peak efficiency.

Their outdoor location leaves fin fan tubes constantly exposed to the elements. Layers of grime and buildup that accumulate can reduce their efficiency over time.

Positioned above or below large fans to help dissipate heat by pulling in ambient air, fin fan tubes are critical components of cooling systems, but when they’re dirty the efficiency of the heat transfer process is reduced and process overheating can occur.

Regular cleaning is ideal for peak efficiency, but it’s not a job for ordinary methods.

Challenges of Traditional Cleaning Methods

Fin fan tube cleaning involves tight spaces and delicate equipment. Traditional cleaning methods often fall short, while also introducing significant complications and downtime.

Hydroblasting & Chemical Foam

Thin metal fins can be bent and damaged by the force of hydroblasting. Water-based cleaning also requires greater downtime with more of the system shut-down to prevent water damage, in addition to requiring the use of water and chemicals (many plants are trying to reduce their water consumption). Hydroblasting is also less effective in reaching confined spaces within complex tube configurations. In some cases, hydroblasting can only clean from the top down, leaving bottom sections out of reach.

Manual Cleaning

While certainly an option, manual or hand cleaning is substantially slower and ineffective for hard-to-reach areas. While sometimes used for delicate parts, manual cleaning is labor-intensive and limited to accessible areas, leaving much of the buildup in more intricate equipment untouched.

How Dry Ice Blasting Cleans Fin Fan Tubes

Dry ice blasting provides gentler and more effective cleaning for fin fan tubes. Advantages include:

Gentle, Adjustable Force

The process uses an adjustable nozzle and customized pressure, gentle enough for thin aluminum fins, but effective in removing dirt and other contaminants.

No Secondary Waste

Dry ice blasting uses CO₂ pellets that sublimate on impact, transitioning directly from solid to gas. The process leaves behind no collateral media.

Water & Chemical Free

A water-free and chemical-free process, dry ice blasting dramatically simplifies the cleaning process, eliminating the messy job of reclaiming and disposing of contaminated water. It also eliminates the corrosion and electrical risks that the introduction of water carries.

Enhanced Heat Transfer

Regular cleaning with dry ice restores the optimal heat transfer capacity of the tubes, improving overall system efficiency and reducing energy consumption of the equipment.

Minimal Downtime

The no-mess effectiveness of dry ice blasting means reduced downtime and minimal disruption to plant operations.
