THE OPERATING ENVELOPE
Two pressure envelopes on this machine, and they are not interchangeable.
The process vessels are certified to 250 psi (17.2 bar), which is what makes straight propane practical: propane sits at 110 psig at 70 F (21 C) and 174 psig at 100 F (38 C) against 16.5 and 36.9 psig for n-butane. See running straight propane. The column jackets are a 22 psi (1.5 bar) space, and the included vacuum pump pulls the process side to -29.5 inHg (-14.5 psi, -1.0 bar).
This is the largest certified solvent charge we build.
290 lb is the certified maximum solvent capacity, and it is the reason this machine exists alongside the Double Barrel. The Double Barrel splits 200 lb across two 100 lb ASME tanks and gives you two independent sides. The Single Barrel puts the whole charge behind four columns on one side. Which one is right depends on whether you want throughput or redundancy, and that is worth a phone call: 541-330-6409.
Figures are transcribed from 3P Certz report ECR-200023-R0, released 24 August 2020, with the Double Barrel and 20 LB capacities from ECR-250902-R0 and ECR-200014-R2.
Read this before you buy it: for most operations the 40 LB Passive Double Barrel is the better machine and it costs less, $350,000 against $367,500. It gives you twice the vessels, redundancy on every one of them, and it is the design in current production. This page exists for the one situation the Double Barrel cannot solve: a room that physically will not take it.
That is what this machine is for. It runs the same 40 LB of throughput in a 52 in x 64 in floor space, and it ships as three crates so the rack can be walked through a 32.5 in man door. If you have the throughput requirement but not the room, this is the layout that fits. If you have the room, buy the Double Barrel.
It runs straight propane. The ASME solvent tank and recovery vessel are rated 250 psi (17.2 bar), and propane's 110 psig at 70 F (21 C) sits well inside that envelope. See Running Straight Propane.
THIS ONE OR THE DOUBLE BARREL
We build two machines at 40 LB and they are not interchangeable.
| This machine, single barrel | Double Barrel | |
| Price | $367,500 | $350,000, and it is the cheaper machine |
| Layout | One barrel, four columns onto one recovery vessel | Two complete 20 LB sides on one rack |
| Solvent vessels | One large ASME tank | Two 100 lb ASME tanks |
| Recovery vessels | One large ASME vessel, 26 in jacket, hot water heated | Two 12 in ASME vessels |
| Molecular sieve | One, 6 in x 48 in | Two |
| Redundancy | None. One vessel down stops the machine | Every vessel doubled. One side runs while the other is down |
| Training a new operator | One set of controls. Two people can work it, but it is slower and most of the work falls on the main operator | Two mirror-image sides. A trainee runs their own side next to your lead, valve for valve |
| Floor space | 52 in x 64 in | 100 in x 44 in x 87 in |
| How it arrives | Three crates, 4,200 lb total, largest is 48 x 60 x 90 in | One crate, 3,000 lb, 144 x 48 x 90 in |
| Gets into a tight room | Yes, three pieces through a 32.5 in door | Separates into two sides |
| Material per run | 18,144 g (40 lb) cured, dry or trim | 18,144 g (40 lb) cured, dry or trim, or 32,659 g (72 lb) live resin |
| Status | Built to order | Current production |
| Our recommendation | Only if your room rules out the Double Barrel | Buy this one |
Not sure which you need? The System Sizing Calculator compares all four of our systems on your schedule, including what each one costs per pound of capacity.
We would rather sell you the Double Barrel. It is less money, it has twice the equipment, and when a gasket goes you keep producing on the other side instead of shutting down. The only honest reason to choose the compact is floor space. Call 541-330-6409 with your room dimensions and door width and we will tell you straight which one you can actually fit.
There is a second reason we steer people to the Double Barrel, and for a lot of owners it matters more than the price. It is the best machine we build for training. A new operator runs one side while your lead runs the other, valve for valve, so when someone leaves, and in this industry someone always does, you are not starting from zero. The compact has one set of controls. Two people can work it, but it runs slower that way and most of the work lands on the main operator. See why the Double Barrel is built to train.
HOW IT GETS INTO YOUR BUILDING
This is the part that decides whether the machine can be installed at all, so here are the real numbers rather than a promise.
| Crate | Size | Weight |
| Side one | 48 x 48 x 72 in | 1,500 lb |
| Side two | 48 x 48 x 72 in | 1,500 lb |
| Third section | 48 in wide x 60 in long x 90 in tall | 1,200 lb |
| Total | Three crates | 4,200 lb |
The Double Barrel arrives as a single 144 in crate. This one arrives in three, which is exactly why it can go into a building the Double Barrel cannot. Once uncrated, the three rack sections pass through a 32.5 in man door and bolt together on site into a 52 in x 64 in footprint.
HOW THE MATERIAL COLUMNS ARE PACKED
Four columns, all loaded the same way, from the bottom up: sintered disc 50 micron dull side up, perforated plate, filter paper, two drop-in rings, then pack your material on top. The plate carries the paper. Paper laid straight on an open disc has nothing to sit on and tears through under differential pressure.
A color remediation column is loaded differently, with a plate at each end of the media bed. Both procedures are in How to Stack a Material Column and a CRC Column.
BUILT, NOT RESOLD
- N.B. Oler is an ASME U stamp shop, with certificate reinstatement expected early 2027. The solvent and recovery vessels are welded, hydro tested and stamped in our own shop in Bend, Oregon.
- The material columns and the molecular sieve are not U stamped and do not need to be. Their inside diameters fall under the ASME BPVC Section VIII Division 1 exemption for vessels of 6 in inside diameter or less, U-1(2)(-i). They are built to the same shop standard and are analyzed in the report alongside the stamped vessels.
- All stainless is fabricated here. Gaskets, filter cartridges and filter socks are purchased parts and are not represented as ours.
- Certified under 3P Certz report ECR-200023-R0, released 24 August 2020, with a third party P.E. report on file for engineering review and permitting.
- Swagelok and Superlok fittings throughout, with traceable material certifications on the pressure parts.
LEAD TIME AND TERMS
- Built to order. Call 541-330-6409 for the current lead time on this configuration.
- Paid in full before the system ships. We do not offer net 30 or purchase order terms.
- Ships LTL freight as three crates totaling 4,200 lb. Freight is quoted and invoiced after the crates are measured, not charged at checkout.

COMMON QUESTIONS
Should I buy this or the Double Barrel?
The Double Barrel, unless your room physically will not take it. It is $350,000 against $367,500, it has twice the vessels, and one side keeps producing while the other is down. The only honest reason to choose this machine is floor space.
Why does the compact cost more than the bigger machine?
Fitting the same 40 LB of throughput into a 52 in x 64 in footprint is harder to build than spreading it across two sides, and it is a made to order design rather than current production.
How is this different from the Double Barrel?
Same 40 lb per run. This puts four columns onto one large ASME recovery vessel and one large ASME solvent tank in a 52 in x 64 in footprint, with no redundancy. The Double Barrel is two complete 20 LB sides, every vessel doubled, in 100 in x 44 in.
Will it fit through my door?
The rack splits into three pieces and goes through a 32.5 in doorway. Floor space once assembled is 52 in x 64 in. Call 541-330-6409 with your room dimensions and door width before you order either machine.
What is the MAWP?
250 psi (17.2 bar) on the process vessels, with 22 psi (1.5 bar) column jackets.
How much solvent does it hold?
The certified maximum solvent capacity is 290 lb, per 3P Certz report ECR-200023-R0.
Which vessels carry the ASME U stamp?
The solvent tank and the recovery vessel. The material columns and the molecular sieve are exempt because their inside diameters are 6 in or less, under ASME BPVC Section VIII Division 1 U-1(2)(-i), so they carry no stamp and do not need one.
Is a vacuum pump included?
Yes, and it pulls to -29.5 inHg (-14.5 psi, -1.0 bar). An N2 regulator is included too.
Is a color remediation column included?
Yes, as standard. If you do not need one we can leave it off, or we can fit a larger one, and the quote is written to match.
What do I have to supply?
Ancillary heating and chilling equipment, and the liquid CO2 or chiller installation, which your local gas supplier does.
What is the lead time?
Built to order. Call 541-330-6409 for the current figure.
Do you offer net 30 or purchase order terms?
No. Systems are paid in full before they ship.
