The Nu-Calgon 4371-75 Tri-Powr HD is a heavy-duty alkaline coil cleaner designed for HVAC technicians and service professionals who need a reliable, no-rinse solution for cleaning condenser and evaporator coils. This product comes in a 19 oz aerosol can and delivers a foaming action that penetrates and lifts grease, grime, and built-up debris from coil surfaces without requiring a water rinse after application. The alkaline formula has a pH of 13.3, making it highly effective at breaking down organic soils and grease that accumulate on HVAC coils over time. Despite its strong cleaning power, the formula is non-toxic, non-fuming, and non-flammable, which makes it safer to use in occupied or enclosed spaces where ventilation may be limited. The cleaner is biodegradable and carries a pine fragrance, reducing environmental impact and leaving a fresh scent after use. It is suitable for both indoor and outdoor HVAC applications, including air handlers, condensing units, and microchannel coils where careful, low-pressure cleaning is essential to avoid damaging the thin metal fins. The non-abrasive, concentrated formula ensures coil surfaces are cleaned thoroughly without physical damage. The aerosol delivery system provides consistent, controlled spray pressure, which is especially important when working with delicate microchannel coil designs. This product meets ANSI Z88.2, CAN/CSA-Z94.4, and OSHA 29 CFR 1910.134 standards, ensuring it aligns with workplace safety and respiratory protection regulations. Manufactured in the USA, the Nu-Calgon 4371-75 is a trusted choice for HVAC professionals performing preventive maintenance and coil cleaning on residential and commercial systems.
The Nu-Calgon 4371-75 Tri-Powr HD delivers powerful, no-rinse coil cleaning in a convenient 19 oz aerosol can, combining a high-pH alkaline formula with a safe, biodegradable profile that meets ANSI and OSHA standards for professional HVAC maintenance work.
