Charged by placing in a refrigerator or ice water, the insert transitions between solid and liquid states at its target temperature, releasing stored thermal energy at a constant rate. Each insert measures 6 inches by 14 inches and weighs 16 ounces. The pack includes 4 inserts. HVAC techs, industrial hygienists, and safety professionals use these inserts to maintain compliant temperature ranges in cooling vests, transport containers, and similar personal protective or temperature-sensitive applications.\u003c\/p\u003e\n\u003cp\u003ePhase change inserts are used in environments where consistent, moderate cooling is required without mechanical refrigeration. Common applications include cooling vest systems worn by workers in hot industrial or outdoor environments, such as rooftop HVAC installations, foundries, and outdoor utility work. The 58 degrees F output temperature is suited for body cooling applications where ice-cold temperatures would be uncomfortable or counterproductive. Each pack of 4 inserts supports multiple vests or extended rotation cycles during a single shift.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDelivers a constant output temperature of 58 degrees F for up to 3 hours\u003c\/li\u003e\n  \u003cli\u003eNon-toxic PCM formula — safe for occupational and personal protective equipment use\u003c\/li\u003e\n  \u003cli\u003eCharges in a standard refrigerator or ice water — no freezer required\u003c\/li\u003e\n  \u003cli\u003eEach insert measures 6 inches by 14 inches for broad surface coverage\u003c\/li\u003e\n  \u003cli\u003eLightweight at 16 ounces per insert to minimize added load on the wearer\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 4 inserts to support crew rotation or multi-vest setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or supplemental insert for cooling vest systems that accept a 6-inch by 14-inch phase change panel.

Place inserts in a refrigerator or ice water bath until fully solidified before loading into the vest pockets. Do not microwave, puncture, or expose inserts to temperatures beyond their rated range. Dispose of damaged inserts per local regulations for non-toxic gel materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Temperature\u003c\/strong\u003e: 58 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHold Duration\u003c\/strong\u003e: Up to 3 hours\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Dimensions\u003c\/strong\u003e: 6 inches x 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Weight\u003c\/strong\u003e: 16 ounces (1 pound)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Package\u003c\/strong\u003e: 4 inserts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Type\u003c\/strong\u003e: Non-toxic phase change material (PCM)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCharge Method\u003c\/strong\u003e: Refrigerator or ice water\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ALLEGRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2379496\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLEGRO","offers":[{"title":"Default Title","offer_id":51268162453810,"sku":"8414-11","price":205.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308910804.jpg?v=1780700860","url":"https:\/\/voomisupply.com\/products\/allegro-2379496-phase-change-insert-58-degrees-f-4-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
