Purfresh Wine is deploying its O3 Generation Container Systems to WineriesPurfresh Wine containers are controlled via a cloud-based software for the pre-crush improvement of winemaking, wine quality and to save harvests from smoke taint caused by wildfires.

At specific concentrations O3 can delicately permeate the skin of the grape.
Rent one or multiple container units: Choices of a 40’ Purfresh Wine container or a 20’ container.
- Daily Grape Volume treated: 5-27 tons per day
- Internal Dims (40’): L 38.2’ x W 7.5’ x H 8.2’ (feet)
- Temperature control range (insulated): −10ºF to +80ºF
- Ventilation (0-260 CMH) will be closed
- Humidity control setting: 75% to 85% targeted RH
- Power: 3-phase, 480 Volt / 20 Amp max draw
- Fan speed (internal air circ.): 3,000 to 6,000 cbm/h (low/high speed)
- Internal in-bin, center harvest bin, ozone level sensor
- “T-bar” dynamic air-flow floors ensure optimum forced air circulation
- Ozone on demand remote control: 0.1 to 20 PPM
