PCM Ice-Liner Technology for Refrigerators & Deep Freezers
At Sinha Thermal Energy Pvt. Ltd., We have developed advanced Phase Change Materials (PCMs) to create high-performance ice liners for the refregerator and deep freezers that ensure stable and reliable cooling even in challenging conditions.Our PCM ice-liners store thermal energy when the compressor is ON, and release it slowly when power goes OFF, acting as a thermal battery inside the refrigerator or deep freezer.This keeps your products safe, maintains uniform temperature, and significantly reduces spoilage.
How PCM Ice-Liners Work :-
(1.) When the refrigerator or freezer runs, the PCM freezes at its designed temperature.
(2.)During power cuts, frequent door openings, or defrost cycles, the PCM melts slowly.
(3.)While melting, it releases stored cooling and keeps the internal temperature stable for long periods.
(4.)This ensures that your stored products remain within the safe temperature range.
Applications :-
Vaccine & medical refrigerators (2°C to 8°C).
Commercial deep freezers.
Ice-cream, frozen food, seafood storage.
Dairy and cold-chain logistics.
Household fridges in high-power-cut regions.
Solar-powered refrigerators.
E-commerce and last-mile cold transport.
Advantages of PCM Ice-Liners Over Traditional Ice Packs:-
1. Temperature Stability:- Unlike water ice (0°C), PCM can be designed to maintain specific temperatures such as −18°C, −12°C, +5°C, etc., ensuring precise cooling.
2. Longer Backup PCM offers higher thermal storage capacity, achieving 6–24 hours of holdover time depending on refrigerator size and PCM quantity.
3. Product Safety +5°C PCM prevents accidental freezing of vaccines and sensitive items.
4. Energy Efficiency By buffering heat load, PCM reduces compressor cycling and lowers electricity consumption.
5. Seamless Integration-PCM ice-liners can be installed:
Behind the inner liner during manufacturing
As add-on panels for retrofit applications
As HDPE or aluminum PCM pouches mounted on side walls or shelves
