Cold chain: freezing and cooling applications with Plentigrade PCMs

Hold precise low temperatures and cut compressor cycling. Plentigrade cooling PCMs deliver plateaux from −30 °C to +6 °C for food and logistics.

Operating temperatures & duty

Charge sources: freezer or blast chiller set below the plateau

Discharge: passive hold in transit/storage

Where it helps

Frozen & chilled food transport and cabinets

Target temperatures Best-fit PCM Typical charge sources
-30 °C M30 (Salt hydrate) Freezer/chiller loop < -30 °C
-15 °C M15 (Salt hydrate) Freezer/chiller < -15 °C
-5 °C M5 (Salt hydrate) Freezer/chiller loop < -5 °C
+5 °C P5 (Organic) Chiller below +5 °C

What PCM should I pick?

Match the product’s required hold temperature. −30 °C for deep frozen, −15 °C for frozen, −5 °C for chilled buffering, +5 °C for refrigeration.

Are organics safe on site?

Organics are combustible and are clearly labelled for handling and storage. If you prefer non-flammable, choose a salt hydrate PCM.

How do I size it?

Start with the plateau temperature, then size for the required kWh at duty cycle. We can provide a quick PCM-versus-glycol check and right-size the pack.

Can I retrofit into existing coolers?

Usually yes. Allow for pack volume, airflow, and loading patterns. We can advise on placement to reduce door-open spikes.
