Precautions for customers installing Lneya’s cryogenic industrial chillers
One. Low temperature industrial chillers need to pay attention to some installation requirements when installing 1. The cryogenic industrial chiller should be installed directly in a horizontal position, do not install it upside down or diagonally 2. Low-temperature industrial chillers generate heat during operation, and should ensure the circulation of cooling air. There should be… Read more Precautions for customers installing Lneya’s cryogenic industrial chillers
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… Read more Introduction of temperature control equipment for cannabis extraction
