This powerful aerosol solvent is specifically engineered to blast through stubborn grease, oil, and grime that standard water-based cleaners leave behind, restoring heat transfer efficiency in seconds. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Performance:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFormulated with a non-conductive, non-flammable solvent base, \u003cstrong\u003eNu-Blast®\u003c\/strong\u003e features an ultra-high-pressure spray pattern that physically dislodges debris from deep within the coil fins. Because the solvent evaporates quickly, it requires \u003cstrong\u003eno water rinsing\u003c\/strong\u003e, making it the ideal solution for rooftop units, cell towers, and remote equipment where water access is limited. Its heavy-duty degreasing chemistry is particularly effective on \"kitchen-exhaust\" fouled coils found on restaurant rooftops. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Function:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeature 1: High-Pressure Blasting Action:\u003c\/strong\u003e Forceful spray penetrates thick fin packs to push dirt out the other side without the need for a pressure washer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeature 2: No-Rinse Solvent Formula:\u003c\/strong\u003e Evaporates completely after cleaning, saving time and eliminating the need for bulky water hoses on rooftops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeature 3: Non-Conductive \u0026amp; Non-Flammable:\u003c\/strong\u003e Safe for use around electrical components and sensitive HVAC circuitry while the unit is powered down.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeature 4: Industrial Strength Degreaser:\u003c\/strong\u003e Specifically breaks down petroleum-based oils and kitchen greases that cause catastrophic head pressure spikes. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Details and Key Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 4290-75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Nu-Calgon (Genuine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Aerosol Condenser Coil Cleaner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan Size:\u003c\/strong\u003e 18 Ounces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolvent Type:\u003c\/strong\u003e Non-Aqueous \/ Non-Flammable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRinse Required:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping Weight:\u003c\/strong\u003e 1.5 lbs \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e🛠️ \u003cstrong\u003eHVAC Depot Pro Tip: The \"Back-to-Front\" Blast\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFor the best results, always spray Nu-Blast® from the inside of the condenser coil pushing outward.
