With zero ODP and a moderate GWP of 2,264, it offers a balanced solution for phasing out R22 without major system modifications. Its composition is designed to closely match R22's operating pressure and capacity while maintaining compatibility with both mineral oil and POE lubricants.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Technical Advantages:\u003cbr\u003e\u003c\/strong\u003eExcellent pressure and capacity match to R22 (within ±5%)\u003cbr\u003eUnique lubricant compatibility - works with existing mineral oil or POE\u003cbr\u003eLow temperature glide (\u0026lt;7°C) for stable system operation\u003cbr\u003eA1 safety classification (non-flammable) per ASHRAE Standard 34\u003cbr\u003eReduced discharge temperature extends compressor life\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;\"\u003e99.1\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-44.1\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;\"\u003e185.5\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;\"\u003e623.66\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\"\u003e99.9\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\"\u003e0.1\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\"\u003e50\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;\"\u003e2037\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\u003eDirect R22 replacement in AC systems (residential and commercial)\u003cbr\u003eCommercial refrigeration retrofit (supermarkets, cold storage)\u003cbr\u003eIndustrial process cooling systems\u003cbr\u003eHeat pumps and chillers\u003cbr\u003eTransport refrigeration units\u003cbr\u003e\u003c\/p\u003e","brand":"Nycoolmate","offers":[{"title":"Default Title","offer_id":44018945556595,"sku":"HFC-R438A","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0675\/9206\/1043\/files\/dd7c65c81af00db4aa96de9b1453460_e1920451-c45c-4c98-ada8-02e184d1d988.jpg?v=1763540545","url":"https:\/\/nycoolmate.com\/products\/r438a","provider":"Nycoolmate","version":"1.0","type":"link"}
