Need more surface area on your recovery or evaporation? Maximize your exposure to heating and chilling by using a tube and shell heat exchanger. By dividing your extraction into many long tubes and using gravity to flow through them, you can create an increase in contact with a decrease in production space. Rated to 500 psi, -90c these heat exchangers will increase your recovery rate safely and efficiently. Made for sanitary butane or propane extraction, these tube and shell heat exchangers are legal lab ready! Like most Butane Extraction Equipment sourced from our warehouse in Nevada, this tube and shell heat exchanger is ASME. Buy with confidence knowing your system is safe.
