About Our Class I, Div. 1 Extraction Booths and Class 1, Div. 2 Hoods

C1D1 Extraction Rooms and C1D2 Hoods

HAL Extraction is a group of individuals dedicated to providing the safest and most cost-effective CID1 and C1D2 extraction solutions for plant oil extraction facilities. We have designed our products to meet applicable NFPA, NEC, and ICC codes as well as fire codes in CA, OR, AZ, and WA. HAL Extraction was established in April of 2016 with the goal of building products that set industry standards for safety in the plant oil extraction industry. Our technology has been developed using industrial hygienists and electrical, mechanical, and manufacturing engineers to make sure that our products are a generation ahead of our competitors. We strive to maintain that lead by working with organizations such as UL, a nationally-recognized testing laboratory, and PSI (Pressure Safety Inspectors) to maintain our lead in product listings and certifications.

Linn Havelick has had a long career in process chemistry, environmental health & safety, laboratories, and hazardous materials.

The idea for the HAL Extraction Booth (patent pending) spawned from the series of explosions that plagued Colorado extraction facilities following the rollout of legal recreational cannabis. When Linn, started working with the plant oil extraction industry, he saw a need for an turn-key extraction solution that would provide a safe working environment while meeting regulatory and code requirements. He developed the HAL Extraction Booth System to provide business managers and entrepreneurs with affordable solutions to the rapidly evolving challenges of the plant oil extraction industry.

Linn started his technical career in the Extractive Metallurgy Department of AMAX Research and Development Laboratory in the late 1970’s. At the end of 2013, the State of Colorado created a requirement for Certified Industrial Hygienists (CIH) to review cannabis extraction facilities. As a CIH, Linn is using background in extraction and safety to help move the plant oil extraction industry into the modern, legal, and safe world. He is currently working with Underwriters Laboratories (UL) on listing and certification criteria for Canada.

Since 2006, Linn has traveled to Eastern Europe many times to work with Romanian universities to provide workshops in environmental health and safety topics. His work contributes to fostering professional connections between occupational health professionals in Romania and Colorado.

Linn holds a Bachelor of Arts in Biology and a Master of Public Administration, both from the University of Colorado at Denver. He has been certified by the American Board of Industrial Hygiene since 1988.
