RayCube Wants to Expand Volcanic Sand Where It Is Used

Field notes

The system is organized around input, expansion, exit, and container modules, with one, three, or six RayCube units operating in parallel. The page lists approximate annual capacities from 1,700 to 10,200 m³ and connection loads from 75 to 450 kW. Its central logistics argument is that dense rhyolite granulate travels to the customer and expands there, avoiding the shipment of a material described as more than 90% air after expansion. Certification under EN 13501-1 is identified as in preparation.
