AHU Coil Cleaning
ABS FINCARE / ABS 707 is a unique blend of surfactants and cleaning agents designed for cleaning AHUs, FCUs, and radiator fins. This non-acid, biodegradable cleaner is safe to use.
Its special foaming action penetrates deep into coils and pushes dirt outward for easy removal. It can be diluted up to 1:5 with water depending on the level of contamination.
High Pressure Drop: Clean or replace air filters
Low Supply Air Flow: Clean or replace air filters
Dirty Air Filters: Clean weekly using warm water or mild detergent
Contaminated Fins: Clean using fin cleaner (ABS FINCARE)
Aluminum coil fins often accumulate airborne contaminants and oxidation due to humidity. These layers act as insulation, reducing heat transfer efficiency between air and refrigerant.
This leads to reduced temperature drop and poor system performance if not cleaned regularly.
Measure supply air flow rate before and after cleaning
Measure refrigerant return and supply air temperatures
Compare supply air temperatures before and after cleaning
Up to 30% energy savings due to improved heat transfer
Ensures proper system operation
Prevents sudden system shutdowns
Reduces mechanical stress on motors, blowers, and compressors
Improves indoor air quality and prevents “Sick Building Syndrome”
Clean coils consume less electricity and significantly reduce operating costs. Studies show that dirty coils can increase energy consumption and operational expenses drastically.
Dirty coils also increase head pressure by 10–20%, causing unnecessary wear on components like compressors and motors, leading to frequent breakdowns.
Regular cleaning improves efficiency, reduces downtime, and eliminates the need for disassembly—saving both time and cost.

Advantages of Fincare Over Caustic Soda
| S.No | Caustic Soda | Fincare |
|---|---|---|
| 1 | Highly caustic and eats into metal surfaces | Contains retardants that prevent corrosion |
| 2 | Highly corrosive and dangerous to use | Easy to handle |
| 3 | Pungent smell makes usage difficult | No pungent smell, pleasant odor |
| 4 | Necessary to use outdoors | Can be used indoors |
| 5 | Non-biodegradable | Biodegradable |
| 6 | No heavy foaming | High foaming cleans from inside out |
