The problem begins with airborne contaminants, such as lube oils, exhaust fumes, dust, bugs, cottonwood lint, and harvest debris. These deposits build up on FF tubes and reduce designed efficiency by blocking airflow across rows of tubes, and forming an insulation barrier around the tubes to reduce heat transfer. The result is reduction in production capabilities, and increase in operating and cost.
Sierra Chemicals’ Green Seal™ certified chemical (E-6) is diluted through our unique foaming process to one side of a cooler allowing gravity to move E-6 through extremely small fin to fin clearances. This readily biodegradable foaming surfactant will penetrate deep into multiple layers of fin tubes then attach and lift the contaminants from the fin surfaces. We use high volume-low pressure water (prevents damage to fins) to flush out the debris in the same direction it entered the cooler.
The result is a unit that will run more efficiently with less downtime. What does this mean to you? More production and operation dollars.
Benefits Over Conventional Cleaning
- No bent fins
- No hazardous chemicals
- Less downtime
- Greater efficiency – Increased air flow
- We remove more debris from all layers of tubes
Sierra Chemicals is your answer to a dirty fin fan unit.
What is Green Seal™?
Green Seal™ is an independent non-profit organization dedicated to safeguarding the environment and transforming the marketplace by promoting the manufacturing, purchase, and use of environmentally responsible products and services.
The Power of Green Seal™
The Green Seal™ on a product means that it not only holds up to rigorous environmental standards, the chemical also has to perform as well, or better, than other non-Green Seal™ approved chemicals.
The Benefits of Green Seal™ Chemicals
- Improves the environment by reducing toxic pollution and waste, while conserving resources and habitats.
- Demonstrates to businesses that environmental responsible products can improve quality and boost profitability.
Our process of cleaning Fin Fans is safer and more effective than conventional high-pressure cleaning methods. We do not damage the fins and we eliminate the fouling debris.
Fin Fan Descaling
Cooling is supplemented by the addition of water dispersed externally on the fins, over time this leads to the build-up of calcium carbonate scale. This scale drastically reduces the efficiency of a cooler, through lack of airflow and insulation, rendering the cooler inoperable without the constant addition of more water; thus compounding the problem.
Rather than attempt to remove the scale with high pressure, which can also damage fins and only removes the surface scale, Sierra Chemicals can safely acidize a cooler to remove all scale from all areas of the cooler.
Procedure 1, Acid Foam: When scale is moderate, Sierra Chemicals begins by gently brushing off as much scale as possible. Then we will apply a mild phosphoric acid into a thick consistency foam that will gently break down the scale, and will not damage your fins!
Procedure 2, Acid Circulation: When the scale problem is severe, Sierra Chemicals can set up a containment system inside the cooler shroud and continuously circulate the correct chemical package designed for the scale. The chemical package is contained and stored to eliminate the potential for environmental damage.
