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

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.
