Fouled Air Cooled Heat exchangers lead to the following problems:
- Low heat transfer efficiency- High pressure drop- High outlet temperature - High energy consumption (fan power)- Low throughput - Low total efficiency
The D. D. T. process is:
EFFICIENT SAFEENVIRONMENTALLY FRIENDLYCOST EFFECTIVE
Other methods ofCleaning Air Coolers
No cleaning at all….
Cleaning with high-pressure water jets
Other methods ofCleaning Air Coolers
Cleaning with detergents (soap, foam)
Cleaning with acids
The DISADVANTAGES of other methods:
No cleaning means low efficiency
Walking on fins causes fin damage
High pressure water causes damage to fins
Foam/Soap evaporates before penetrating
Acid causes damage to fins
Damaged fins due to other techniquesWe guarantee that our cleaning will not damage the aluminum fins
D. D. T. dry-chemical cleaning method(1) spray dry chemicals, bottom-to-top
(2) Rinse with water top-to-bottom
Our chemicals
Nano-sized powder that does not damage the fins, penetrates all the way through the bundle.
Powder flow acts differently than Liquid flow
Cleaning in action
No need for scaffolding No need to enter into the housingNo need to remove the safety net
Cleaning during normal operation
Visible Results !!
Half-clean Half-dirty fins
Inlet/Outlet temperatures Airflow Power of the fan
Parameters to monitor:
Before Cleaning After Cleaning
Before Treatment: T in = 47.9CT out = 40.8C
After Treatment: T in = 47.2CT out = 37.5C
Delta T = 3.3 C (8.1%)
Throughput benefit: 1,180 $/dayEnergy consumption benefit: 243 $/day
Example of increased Air Cooler efficiency
Environment: The D. D. T. process is Environmentally friendly
NO creation of wasteChemicals are salts and easily dissolved in water Chemicals are compatible with biological treatment
SAFETY: The D. D. T. process is SAFETemporarily turn-off each fan for only 40-45minNo Scaffolding needed
Chemicals are non-corrosive and compatible with all types of metallurgy, non-hazardous, non-explosive, non-toxic
Excellent results
Other methods : Cause fin damage Superficial Cleaning
The D. D. Technology process is: EFFICIENT SAFE ENVIRONMENTALLY FRIENDLY COST EFFECTIVE
