Allegro 2379496 Phase Change Insert 58 Degrees F 4 Pack

Product Description

The ALLEGRO 2379496 is a phase change insert (PCI) that uses a non-toxic phase change material (PCM) to deliver a steady, controlled temperature of 58 degrees F for up to 3 hours. 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.

Phase 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.

Key Features

• Delivers a constant output temperature of 58 degrees F for up to 3 hours
• Non-toxic PCM formula — safe for occupational and personal protective equipment use
• Charges in a standard refrigerator or ice water — no freezer required
• Each insert measures 6 inches by 14 inches for broad surface coverage
• Lightweight at 16 ounces per insert to minimize added load on the wearer
• Sold in a pack of 4 inserts to support crew rotation or multi-vest setups

Compatibility

Designed as a replacement or supplemental insert for cooling vest systems that accept a 6-inch by 14-inch phase change panel. Verify pocket dimensions and temperature rating requirements before installation.

Installation Notes

Inserts are charged by a licensed or trained safety professional responsible for PPE program management — no specialized tools or trade license is required, but inserts should be inspected for leaks or damage before each use. 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.
