A significant yet hidden cost of plant oil extraction using volatile chemical solvents, such as butane hash oil (BHO) in the hemp and marijuana industries, is the heating or cooling of the air used to evacuate the volatile solvents from blast-proof rooms required by fire codes to ensure employee and building safety.
If these blast-proof rooms are not designed properly, the HVAC costs alone can larger than the labor expense in colder climates. Conditioning this wasted air can cost extractors up an extra $25,000-50,000 per year depending on regional temperatures and energy prices without the proper design and technology.
HAL Extraction Technologies’ booths patented technology and patent-pending designs save this cost, and pay for the cost of the booth within a year or two. Plant oil extraction rooms made by HAL Extraction Technologies combine patented AMAV (Active Monitoring + Adaptive Ventilation) technology with a patent-pending design called DVAC (Distributed Vapor Airflow Capture) Adaptive Ventilation and a patent-pending Focused Flow design engineered to minimize the wasted air by 83%.
The HVAC costs are driven by the energy required to raise or lower the temperature of the air used to evacuate the solvents from the blast rooms. To lower costs, HAL’s technology and design reduces the amount of air needed to ensure employee safety and meet the fire codes.
The HVAC costs are higher in climates with more extreme temperatures in winter or summer and higher energy costs. Depending on the local climate and cost of electricity, this results in a savings of $74-$106 in the Northeast US, about $53 per shift in Arizona, C$17-C$50 in Canada.
