BET Series
BHO closed loop extractors
The BET Series is a professional closed-loop BHO extraction system designed for efficient cannabinoid and terpene extraction using butane and hydrocarbon solvents. Built for controlled solvent recovery, process consistency, and operator safety, BET extractors help produce high-quality concentrates while minimizing solvent loss and environmental exposure.
Preserve More Than Potency
Capture Flavor. Maximize Yield. Extract With Control.
Unlike many extraction methods that can degrade delicate aromatic compounds, hydrocarbon extraction with butane operates at low temperatures, helping preserve volatile terpenes and the original plant profile. Closed-loop systems are widely used in commercial extraction because they allow solvent recovery in a sealed environment with greater process control and efficiency.
Built for Every Scale of Extraction
The BET Series includes multiple extractor sizes designed for different types of users — from smaller private operators and craft producers to demanding commercial extraction facilities.
Smaller models are ideal for low-volume processing, product development, and boutique extraction workflows, while larger systems are designed for higher throughput, continuous production, and commercial-scale operations.
No matter the production size, every BET extractor is built around the same principles:
- controlled closed-loop extraction
- efficient solvent recovery
- terpene preservation
- and reliable, repeatable performance
This allows users to choose a system that matches their current production
Why Choose BET Extractors?
Closed-Loop Safety Design
Closed-loop extraction recovers and reuses solvent, reducing flammable gas exposure compared to open blasting methods.
High Extraction Efficiency
Butane efficiently dissolves cannabinoids and terpenes while limiting unwanted compounds such as chlorophyll and excess plant material.
Scalable Workflow
Whether for small-batch production or commercial-scale extraction, the BET Series is designed to support consistent processing workflows.
Preserve Terpenes & Aroma
Hydrocarbon solvents such as butane are valued for their low boiling point and selectivity, which helps preserve heat-sensitive terpenes and flavor compounds during extraction.
Solvent Recovery & Lower Waste
Closed-loop systems recycle the solvent throughout the extraction cycle, reducing operational losses and improving efficiency.
Designed for Professional Extraction
BET extractors are built for repeatable, controlled extraction processes with efficient solvent recovery and stable operating conditions.
How BET Extraction Works
Step 1
Material Loading
Plant material is placed into the extraction column inside the sealed system.
Step 2
Solvent Wash
High-purity butane passes through the material, dissolving cannabinoids, terpenes, and desired compounds from the plant.
Step 3
Separation & Collection
The solvent carrying extracted oils moves into the collection chamber where the concentrate is separated.
Step 4
Solvent Recovery
The butane is recovered back into the solvent tank inside the closed-loop system for reuse in the next cycle.
Step 5
Post-Processing
The extract is further refined and purged under vacuum conditions to remove residual solvent and achieve the desired final consistency.
Commercial closed-loop extraction systems are specifically designed to keep hydrocarbons contained during operation, unlike outdated open-blast methods where solvent escapes into the environment.
Built for Controlled Hydrocarbon Extraction
Hydrocarbon extraction is highly effective — but it must be performed correctly.
Butane is a flammable solvent and should only be used in properly designed closed-loop systems, in appropriate professional environments with proper ventilation, gas detection, and trained operators. Industry safety standards emphasize the importance of sealed systems, pressure-rated equipment, and controlled operating conditions.
BET Series extractors are designed to support safe and controlled hydrocarbon extraction workflows when operated according to proper procedures and local regulations.

Everything You Need to Know
1. Is BHO extraction safe?
Hydrocarbon extraction can be safe when performed using properly designed closed-loop systems in professional environments with ventilation, gas detection, pressure-rated equipment, and trained operators. Most risks associated with BHO extraction come from outdated open-blast methods or improper operation.
2. Why use butane for extraction?
Butane is highly effective at dissolving cannabinoids and terpenes while operating at relatively low temperatures. This helps preserve flavor, aroma, and volatile compounds that can be damaged by heat.
3. What does “closed-loop” mean?
A closed-loop extractor keeps the solvent contained inside the system throughout the extraction and recovery process instead of releasing it into the atmosphere. This improves efficiency and significantly reduces solvent exposure.
4. Does the final extract contain butane?
Professional extraction workflows include solvent recovery and vacuum purging processes designed to remove residual solvent from the final product. Proper post-processing is essential for product quality and compliance.
5. Why do professionals prefer hydrocarbon extraction?
Hydrocarbon extraction is widely used because it can preserve terpene profiles, achieve high extraction efficiency, and produce a variety of concentrate consistencies such as shatter, wax, budder, and live resin.
6. What solvents can be used?
Closed-loop hydrocarbon systems commonly use butane, propane, isobutane, or blended hydrocarbon solvents depending on the desired extraction characteristics and workflow.
