SHW 120L Subcritical Hot Water Extraction System
A solvent-free 120L production system that extracts polar, water-soluble compounds with pressurised hot water, delivering both a concentrated extract and an aromatic water.
Description
The SHW 120L Extraction System doubles the capacity of our subcritical hot water platform for steady production. Using pressurised hot water as its only solvent, it dissolves the polar, water-soluble fractions of a botanical with no organic solvent, and delivers two products from every run: a concentrated extract and a fragrant aromatic water. The 120 L vessel is built for repeatable, higher-volume output.
Solvent-FreeNo ethanol, no gas – water is the only solvent.
Water-BasedPressurised hot water dissolves polar actives.
Polar ActivesIdeal for polyphenols and water-soluble compounds.
Food-SafeNothing to recover, dispose of, or declare.
Aromatic WaterEach run also yields a saleable hydrosol.
Residue-FreeNo solvent residue in the finished extract.
Two products from one run
Botanical extract
Aromatic water
Hot water under pressure, at production scale
Subcritical hot water extraction relies on a simple fact: when water is heated under pressure it stays liquid above 100 °C and becomes a far more effective solvent for many plant compounds. The 120L system heats water in a sealed, pressurised vessel and circulates it through a larger charge of botanical, dissolving the polar and water-soluble fractions while the pressure stops the water flashing to steam.
As the loaded water cools and the pressure is released, the heavier extract separates from the lighter aromatic water, giving two distinct products from a single batch. The larger vessel keeps high-volume runs consistent, and because water is the only solvent there is nothing to recover: the extract is residue-free and the aromatic water is ready to use as a hydrosol.

Frequently asked questions
Same subcritical hot water process and the same dual-output result, with double the vessel volume for higher, repeatable production throughput.
It uses only pressurised hot water, no ethanol or gas, so it is fully solvent-free with nothing to recover or dispose of.
Two products: a concentrated botanical extract and a fragrant aromatic water (hydrosol), both usable.
Polar and water-soluble compounds such as polyphenols, along with volatile aromatics that report to the hydrosol.
380 V three-phase, around 20 kW for heating, in a 2000 × 1400 × 1100 mm footprint at roughly 750 kg.
Yes. It is a rated pressure vessel with automatic pressure relief, over-temperature protection and hot-surface guarding, and it uses only water.
