Important Chillers in the Marijuana Oil Extraction Process

The Chemistry Component

Marijuana oil (CBD oil) is becoming more popular with its medicinal purposes. The more concentrated, the “higher amounts of cannabinoids in smaller, more discreet packages,” as reported by GEN. To attain quality marijuana oil, “specialized chemistry and engineering skills” are necessary.

“Plant extractions involve grinding up the organic material and bathing it in a solvent to pull out the desired components.” The commonly used solvents are “hydrocarbons, supercritical CO2, and ethanol.”

Solvent Review

Each solvent has its pros and cons in the process of marijuana oil extraction. As stated, the solvent selection “depends on what you’re trying to accomplish, and at what scale,-.”

Hydrocarbons are popular, due to the ease of use, ability to “capture a wide array of compounds at reasonable temperature and pressure.” The downside is their flammability in large quantities, and they capture elements that no one wants.

Carbon Dioxide (CO2) is known to have the best results. This solvent is “non-flammable, inexpensive, and environmentally-friendly.” In its fluid state, “supercritical CO2 is “able to penetrate the cell and draw out the soluble compounds.” The only negative factor is CO2 is reported to be “less powerful.”

Ethanol “extracts the cannabinoids and terpenes more efficiently than C02 and more safely than hydrocarbons, but it also pulls out undesirable components, such as chlorophyll.” For this reason, “more distillation and purification steps” are necessary “to clean it up.”

The Chiller Component

Temperature control is critical in the marijuana / HEMP oil extraction process, as reviewed on LabX.

Temperature Review

Using a hydrocarbon process “requires great attention to safety due to flammability -. Maintaining the pressurized hydrocarbon in the liquid state requires low temperatures. Recirculating temperature control units (TCUs) that can provide cooling to -60°C (-76°F) and below facilitates this process.”

With a CO2 extraction process, “tweaking the temperature and pressure affords CO2 systems the ability to yield extracts with a complete terpene profile.”

Utilizing ethanol, there is a commonly-used process where the solvent is brought down to below “-20 degrees C (-4 degrees F) either in a room or freezer and then pumped into a container of cannabis.”

No matter the extraction process, winterization is required in “removing the plant lipids, fats, and waxes,” which requires low temperature control.

The JCY Component

At J.C. Younger (JCY), we have six decades of experience in new manufacturing and remanufacturing chillers for almost any type of application out there, and we are becoming well-known for our marijuana / cannabis and CBD chiller designs in the industry. Our system can cool as cold as -100F, although we find that the -20 to -40 seems to be best for this application.

Our chillers offer the quality you’re looking for when it comes to the accurate and consistent temperature controls needed. We are well-versed and well-equipped to offer you our expert services when it comes to designing the most dependable chiller your extraction process requires.

Along with proper maintenance and cleaning of our chiller systems, we are confident that our chillers will deliver the highest efficiency needed for the marijuana oil extraction process. We will review everything you need to know and do to keep a JCY chiller efficiently running.

Sam graduated from Dunwoody College with a degree in HVAC Service, and started out working in the resident side of work. After many years in the residential side of work, Sam took a chance back in 2018 to work in the commercial side of hvac with Jc younger. Since started working with them, Sam has been streamlining Jc younger to make the service side quicker at getting customer back to cooling right away. He always puts the customer needs first, giving them great customer service, and getting them back cooling right away. When Sam is not at work he enjoys hitting up breweries around the area, going up to the cabin, and doing remodeling projects. He also enjoys going out to lake of the woods for some good walleye fishing.In his free time he enjoys taking his grandmother out for meals, fishing and spending time with girlfriend and dog Sara.



Sandy has been in the background of JCY since a baby, growing up playing on chiller systems in the large 12,000SQFT pole shed JCY stores units in. Sandy started working at a young age doing simple tasks like sweeping, painting, organizing Copper fittings and other small tasks. In 2005 Sandy started his 4 year degree at Dunwoody College and graduated in 2007.

During his schooling their he also started his apprenticeship under his fathers supervision. The training consisted of installs of glycol piping in the field, building first chiller and assisting with Chiller service repairs. In 2006 he started learning the in and outs of breweries, and has been JCY’s brewery specialist since then. A challenge he took on was glycol piping a 30 bbl brewery by him self and completed that task in less than 20 day with 16 hour shifts.
