Pluss PCM: The timeline


Phase Change Materials (PCMs) &

the three questions

5


Why

□ Prolongs the duration at which temperatures(cold/hot) need to be maintained without external source.

6


□ A green concept – reduces pollution□ Shift peak loads to off-peak hours (a storage device)□ As a back-up

□ Save Energy/Cost

Pluss PCM: The range8

Micro-encapsulated

PCM

Organic Hydrated

�Hydrated salts based PCMs are available for the entire gamut of functional temperatures

Organic


Organic PCMs

Form stable PCMs

Hydrated salts

�Organic PCMs, microcapsules and Form-stable PCMs available in the mid-temperature range

�Wide temperature range: -36 ⁰ C to 89 ⁰C

PCM Characteristics

□ Very high Latent Heat Capacity □ Tailorable for specific

temperature requirements

□ Easy handling ; can be filled in a variety of encapsulations 150

□ Cheap & very stable over long durations

□ Repeatable phase change cycles

□ Low / No flammability□ Non Toxic and Non

combustible
