It’s probably no surprise that aside from labor, energy costs for refrigeration equipment is the biggest expense for the cold storage industry. 3fficient’s innovative cold storage packs bring dramatic energy cost savings to a rapidly expanding industry saddled with bloated energy bills. Each self-contained pack uses patented phase change materials to passively stabilize product temperatures and allow refrigeration compressors to shut off during the heat of the day, often for many hours. No plumbing, wiring, structural or electrical engineering is needed. These tiny thermal energy storage packs work so well, the total energy savings often exceed 35%. Even more if demand normally drops off at night.
If you have solar, your refrigeration units can run off the solar power during the day – with the ice packs providing cooling when solar power is not available. Even better, they provide passive back up cooling for hours and sometimes days to protect your valuable product should your refrigeration units go down.
