Key Features & Trade Benefits

• Light-rinse on condensers (as needed) — knock off loosened muck with a quick rinse. Benefit: faster rooftop turnarounds and less mess.
• Expanding foam action — pin-spray penetrates deep between fins. Benefit: restores airflow, lowers head pressure, and cuts compressor strain.
