Helium cold storage battery

Helium cold storage battery

Helium battery is designed to maintain and maintain the desired temperature for several hours. To use, you need to fill a packet of 400 g of water through the top valve. The valve on the bag is one-way and does not let liquid out. After a few minutes, the water in the bag will become gel-like. Before use, the helium bag should be placed in the freezer for several hours. Use batteries together with a thermos bottle or car cooler.

In beekeeping, helium accumulators are used to maintain temperature during transportation of frozen royal jelly.
