PHASE CHANGE MATERIAL TECHNOLOGY
PCM Coolers
Reusable Cooling Without Freezer
Lightweighted coolers powered by Phase Change Material (PCM). Stay cool for up to 60 minutes — no electricity, no melting ice, no pre-freezing required.
INTRODUCTION
What is a PCM Cooler?
A PCM (Phase Change Material) Cooler is an innovative cooling device that absorbs heat through solid-to-liquid phase transition — keeping you comfortable without any electricity or messy melting ice.
❄️
No Pre-Freezing Required
The PCM inside freezes at approximately 28°C (82°F). It can crystallize in air-conditioned rooms, refrigerators, or even cool tap water — no freezer necessary.
🧊
Gentle, Soothing Coldness
Unlike traditional ice packs at 0°C that risk ice burns, PCM delivers smooth, gentle cooling between 20–28°C — safe even for prolonged use on bare skin.
🔋
Zero Electricity
Purely physics-based cooling. No batteries, cords, or charging. Just freeze it, wear it, and stay cool. Ideal for outdoor activities where power is unavailable.
♻️
Eco-Friendly & Reusable
Each unit can be re-frozen and reused over 500 times. No disposable waste, no condensation drips, no wet mess. One purchase lasts years of daily use.
⚙️
BPA-Free TPU Material
Made from phthalate-free, BPA-free Thermoplastic Polyurethane (TPU). Durable yet soft against skin, resistant to punctures and tears.
📋
Ultra-Lightweight Design
With approximately 20% lighter weight than same volume of water. The neck coolers sits comfortably on your neck without pressure. Perfect for all-day wear during work, sports, or travel
TECHNOLOGY
How Does PCM Work?
The secret is in the Phase Change Material inside. As it absorbs heat from your body, it changes state from solid to liquid at a constant temperature — providing steady, long-lasting cooling.
❶ Crystallize the PCM
Place in a refrigerator (~4°C) for about 20 min, or leave it in an AC room below 25°C until fully solidified.
❷Absorbs Body Heat
When worn, the solid PCM gradually melts into liquid by absorbing heat from your body surface at a stable 20–28°C
❸Lasts 40–60 Minutes
Provides continuous cooling for 40 minutes up to over an hour depending on ambient temperature.
USE CASES
Who/where to Use PCM Coolers?
From professional athletes to office workers, parents to commuters — anyone who needs reliable, hassle-free cooling benefits from PCM technology.
Fitness & Outdoor Activities
Great for summer camps, playground outings, field trips, and outdoor sports. Lightweight design won’t burden kids during active play.
Office & Remote Work
Stay focused and comfortable during long work sessions, video calls, or hot summer days when AC isn’t enough. Silent, cordless, and discreet for any workplace environment.
Daily Commute & Travel
Cycling, walking, or commuting in hot weather? The neck cooler stays securely on your neck even while moving actively. Perfect for urban professionals and outdoor workers.
