With zero Ozone Depletion Potential (ODP) and significantly lower discharge temperatures, R421A extends compressor life while maintaining reliable cooling performance. Importantly, it is compatible with existing mineral, alkylbenzene, and POE oils, eliminating the need for costly lubricant changes during retrofits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Technical Advantages:\u003cbr\u003e\u003c\/strong\u003eZero ODP for environmentally responsible cooling\u003cbr\u003eNo oil change required when replacing R22\u003cbr\u003eLower discharge temperature reduces compressor stress\u003cbr\u003eExcellent energy efficiency and cooling capacity\u003cbr\u003eLow glide (\u0026lt;1°C) ensures stable system performance\u003cbr\u003eProven retrofit solution for existing R22 systems\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable height=\"43\" style=\"width: 98.6266%; height: 242.516px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 43.1134%; height: 19.5938px;\"\u003eParameter\u003c\/td\u003e\n\u003ctd style=\"width: 56.7778%; height: 19.5938px;\"\u003eSpecification\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 34.3281px;\"\u003e\n\u003ctd style=\"width: 43.1134%; height: 34.3281px;\"\u003eMolecular Weight\u003c\/td\u003e\n\u003ctd style=\"width: 56.7778%; height: 34.3281px;\"\u003e111.7\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 43.1134%; height: 19.5938px;\"\u003eBoiling Point (1atm,°F)\u003c\/td\u003e\n\u003ctd style=\"width: 56.7778%; height: 19.5938px;\"\u003e-41.2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 43.1134%; height: 19.5938px;\"\u003eCritical Temperature (°F)\u003c\/td\u003e\n\u003ctd style=\"width: 56.7778%; height: 19.5938px;\"\u003e181\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 43.1134%; height: 19.5938px;\"\u003eCritical Pressure (psia)\u003c\/td\u003e\n\u003ctd style=\"width: 56.7778%; height: 19.5938px;\"\u003e568.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 22.6562px;\"\u003e\n\u003ctd style=\"width: 43.1134%; height: 22.6562px;\"\u003ePurity % ≥\u003c\/td\u003e\n\u003ctd style=\"height: 22.6562px; width: 56.7778%;\" width=\"112\" height=\"22\" class=\"et2\"\u003e99.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 22.6562px;\"\u003e\n\u003ctd style=\"width: 43.1134%; height: 22.6562px;\"\u003eMoisture ppm ≤\u003c\/td\u003e\n\u003ctd style=\"height: 22.6562px; width: 56.7778%;\" width=\"125\" height=\"22\" class=\"et2\"\u003e10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 22.6562px;\"\u003e\n\u003ctd style=\"width: 43.1134%; height: 22.6562px;\"\u003eAcidity ppm ≤\u003c\/td\u003e\n\u003ctd style=\"height: 22.6562px; width: 56.7778%;\" width=\"120\" height=\"22\" class=\"et2\"\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 22.6562px;\"\u003e\n\u003ctd style=\"width: 43.1134%; height: 22.6562px;\"\u003eVapor Residue ppm ≤\u003c\/td\u003e\n\u003ctd style=\"height: 22.6562px; width: 56.7778%;\" width=\"158\" height=\"22\" class=\"et2\"\u003eNot Available\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 43.1134%; height: 19.5938px;\"\u003eOzone Depletion Potential\u003c\/td\u003e\n\u003ctd style=\"width: 56.7778%; height: 19.5938px;\"\u003e0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 43.1134%; height: 19.5938px;\"\u003eGlobal Warming Potential\u003c\/td\u003e\n\u003ctd style=\"width: 56.7778%; height: 19.5938px;\"\u003e2600\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIndustry-Standard Applications:\u003c\/strong\u003e\u003cbr\u003eResidential \u0026amp; commercial air conditioning (ducted \u0026amp; ductless)\u003cbr\u003ePackaged rooftop units\u003cbr\u003eRefrigerated display cases \u0026amp; cold storage\u003cbr\u003eHeat pumps and split systems\u003cbr\u003eRetrofit projects for R22 phase-out compliance\u003cbr\u003e\u003c\/p\u003e","brand":"Nycoolmate","offers":[{"title":"Default Title","offer_id":44019042812019,"sku":"HFO-R421A","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0675\/9206\/1043\/files\/a5b89b980e74a5ba4e487b609bb4196_a4ab58db-01ed-4093-96c5-d129bf72d9e8.jpg?v=1763539697","url":"https:\/\/nycoolmate.com\/products\/r421a","provider":"Nycoolmate","version":"1.0","type":"link"}
