Innovations to close the gaps - PCMs

Temperatures maintained without external source. -37°C to +89°C .

Back-up for temp. critical applications. Up to 72 hours.

Reduces energy consumption, noise and emissions. Uses off peak electricity.

Increases Payload. No cooling equipment, doubles as insulation too.

Pluss's Offerings

What are PCMs ? Materials that can store large amount of heat energy in the form of

latent heat

Release/absorption of heat at almost constant temperature

Also called Passive cooling materials.

Heat Absorption / Release process repeatable over a substantial

number of cycles (~ 3000 or more)

PCM Characteristics

□ Very high Latent Heat Capacity

□ Tailorable for specific temperature requirements

□ Easy handling; can be filled in a variety of encapsulations

□ Cheap & very stable over long durations

□ Repeatable phase change cycles

□ Low / No flammability□ Non Toxic and Non

combustible

For T = 15 K

PCM’s Latent heat = 225 kJ / kg
