Non-acid delayed-foam coil cleaner for evaporator and condenser coils in HVAC systems, refrigeration units, and chillers — no dismantling or manual rinsing required. Delayed foaming action penetrates deep into coil fins to loosen grease, dust, tobacco film, lint, and airborne debris. Natural condensation from the unit’s cooling cycle flushes contaminants out automatically, reducing labour time on routine maintenance. Dual quat formulation deodorizes as it cleans, neutralizing odours and leaving a fresh citrus scent. High-pressure jet tip delivers precise directional coverage in tight, vertical, and hard-to-reach spaces. Suitable for wall-mounted and ceiling-mounted air conditioners, refrigeration chillers, and remote cooling systems in commercial buildings, hospitality venues, and light industrial environments. Improves airflow and heat exchange efficiency to reduce energy consumption and extend equipment service life.
