Introduction of temperature control equipment for cannabis extraction
CO2 is a unique solvent because its dissolving power can be changed by simply adjusting the temperature and pressure during the extraction process. When the pressure and temperature of CO2 are higher than 1083 psi and at 88F, CO2 is considered supercritical. If the temperature drops below 88F, CO2 becomes liquid, called subcritical. Supercritical CO2 (SCCO2) extraction is a strong solvent that can extract all lighter (volatile oil, light wax) and heavier molecular weight (heavy wax, lipid, fa...

Is it right to extend battery life by lowering the ambient temperature?
The battery can work in a wide temperature range, but this does not allow the battery to be charged under high temperature conditions. The charging process is more delicate than the discharging process, and extreme care must be taken. Extreme cold and high temperature will reduce the charge acceptance, so the battery temperature must be adjusted to moderate before charging. The fast charging limit for most batteries is 5°C to 45°C; for best results, please consider narrowing the temperature r...
