Thermafold
Rip out the gas boiler. Keep the process.
Thermafold builds heat pumps that actually reach the temperatures food and chemical lines need, so a plant can retire its gas boiler without redesigning the whole line. The units ship as skids and stack to match whatever a site's load happens to be.
Process heat is one of the least glamorous, hardest-to-abate slices of industrial emissions, and most of the answers on offer are a decade out. Sofie's is a retrofit you can bolt on this year. We'll take the boring, installable version every time.

Sofie Bakker
Co-founder & CEO
Sofie designed industrial refrigeration for years before deciding the more interesting problem was running the same cycle in reverse, hot enough to matter. Thermafold is that idea, shipped as hardware.
