NanoFreeze makes a patented bio-nanofluid: nanoparticles bonded to ice-nucleating proteins, dissolved into the water already running through industrial chillers and HVAC loops at under 5% concentration. It raises the water's thermal conductivity so the system cools faster and the compressor works less, delivering up to 40% energy savings (and as high as 60% in chiller pilots) with no equipment replacement. A drop-in, equipment-agnostic, biodegradable retrofit.
