Four closed loop hydrocarbon systems, built in Bend, Oregon, on the same architecture. This sheet compares the three most operations choose between. The fourth, the 40 LB single barrel compact, is for a room that will not take the Double Barrel. They differ in how much biomass they hold, not in how they work. Every one is passive recovery, 250 psi, ASME certified, and runs crude or live resin without reconfiguration.

Every system: ASME Section VIII Division 1 pressure vessels, in-line stainless sintered filtration, sight spools, 3/4 inch jacketed chilled recovery lines at 4 or more pounds per minute, and cooling by liquid CO₂, liquid nitrogen or chiller. Configurations vary by build, your build sheet governs.

HOW TO CHOOSE

The honest version, rather than the one that sells you the biggest machine.

Start with your biomass supply, not your ambition

The most common mistake is buying for the volume you hope to have in two years. A 40 LB system running at a third of capacity costs the same to own as one running full, and it consumes about 156 L of LCO₂ per run, 78 L on each side, whether the columns are packed or not. Buy for the material you can actually feed it this year. The racks are laid out so a second pair of material columns can be added later without rebuilding the skid.

Then count your ovens

Extraction is rarely the bottleneck. Five runs a shift on a 20 LB system puts 45 kg of biomass through the machine, and the output has to be purged, and then packaged. If your vacuum oven bank and your packaging line cannot keep up with a 20 LB system, a 40 LB will not make you more product, it will make you more backlog.

Getting it into the room

Both systems are built to be moved in. The 20 LB rolls in on its own rack at 30.25 inches wide. The 40 LB is 110 inches long assembled, which fits almost no doorway, so the rack separates into sections, goes through the opening, and is reassembled on the other side. Measure your narrowest point of access, the door, the corridor turn, the elevator, and tell us before the truck is booked. It is far cheaper to plan the route than to take a wall out.

Then check your room and your power

The 40 LB draws 24 to 48 kW on the hot side and doubles your solvent Maximum Allowable Quantity to 200 lb, which changes what your AHJ will approve. Two systems that fit the same floor space can have very different permitting outcomes. See Site Requirements and Utilities.

The short answer

Most operations should start with the 20 LB.

It handles 9,000 g of dry material or 36 lb of live resin per run, carries a full PE report for permitting, and the rack is built to be expanded. Step up to the 40 LB when you are genuinely running the 20 LB to capacity and your post-processing can absorb the output.

WHAT THE DOUBLE BARREL ACTUALLY BUYS YOU

The 40 LB Double Barrel is two complete 20 LB sides built back to back on one rack.

Each side has its own 100 lb solvent tank, its own pair of material columns, its own color remediation column, its own molecular sieve and its own heated recovery vessel. Both sides run every cycle, so a full run is both sides: 40 lb of cured, dry or trim, or 72 lb of live resin.

Because every vessel is doubled, one side can keep producing while the other is down for service, and a lead operator and a trainee can run mirror-image sides next to each other. See the Double Barrel page.

ACCESSORIES AND STANDALONE EQUIPMENT

Drop-in tube-in-shell condenser	6" tri clamp connection, adds 6" of height and inserts 6-1/2" into the vessel. 1,100 in² of cooling surface, 250 psi on the solvent side, CRV rated 100 psi with a 22 psi inlet needle valve. Adds 60 percent cooling surface to an empty 100 lb solvent tank and 125 percent when that tank is half full
Stand-alone Aqua-Tech CRC column	4 inch and 6 inch. 250 psi PRV, gauge -30 inHg to 300 psi, sight spool, jacketed bottom spool for thermal control, on its own rolling rack. Filters included
Hot water skid	150 psi, 80 to 185 °F, 6 gpm, 26" × 34" × 66"
C1D1 hot plate	Billet aerospace-grade aluminum, 20 psi max, 180 °F max, 1 gpm, 18" × 12" × 1.5", 216 in² surface. 1/4" MNPT no-spill quick connects, manifoldable

WHAT SHIPS WITH EVERY SYSTEM

The 2026 Training Binder, including the Hydrocarbon Operators Manual, sintered filter technical specifications, safety and process training, technical briefs on CRC media, molecular sieves, diamond formation and cannabinoid storage, an operators run log, a certification exam and a certificate of completion.
A full PE report for engineering review and permitting.
A serialized Certificate of Conformance with site-specific seismic calculations, on request for your AHJ.
Onsite commissioning and training, three days minimum and five days recommended. Training is required and is quoted separately at $3,500 per day. It is not included in the purchase price.

Gaskets, clamps, fittings and valves for every system are stocked and ship immediately. Relief valves are usually on the shelf. When a setting is out, lead time is typically one to two weeks, and the longest we have ever seen is 12 weeks. The service schedule and reorder list for your model is in the Operators Manual and on the product page.
