20 LB Closed Loop Extractor, ASME Certified Hydrocarbon System
ABOUT THIS PART
ASME certified 20 LB passive closed loop hydrocarbon extraction system, $160,000. Two 6 in x 48 in jacketed material columns, a 12 in x 52 in ASME recovery vessel, a 100 lb ASME solvent tank and a 6 in x 24 in molecular sieve on a modular rack.
Recovery is fully passive, so there is no solvent pump to service. The rack is laid out so a second pair of columns or a CRC column can be added later without rebuilding the skid. This is the system most operations should start with.
It runs straight propane, not only propane blends. ECR-200014-R2 certifies the solvent vessel for propane or butane, and propane's 110 psig at 70 F (21 C) sits well inside the 250 psi (17.2 bar) MAWP. See Running Straight Propane.
The gasket sets the cold limit on this machine, not the steel, and all three pressure zones are rated well below what the steel calculates to. The two charts below the description give the temperature bands and the pressure margins, both transcribed from 3P Certz report ECR-200014-R2.

HOW TO BUY IT
The price is published so you can budget against it. The order goes out on a written quote rather than a cart checkout, because the configuration, the freight and your site all change what it says. Call the shop at 541-330-6409.
Three things get a quote written:
- Throughput. Material per run and runs per day. That settles 20 LB against 40 LB.
- Your room. Floor space, ceiling height and the width of the door the crate goes through.
- Your permits. Who your AHJ is, whether the room is C1D1 classified, and whether anyone has asked for ASME stamps, a PE report or a Certificate of Conformance. This system carries all three.
You get back the configuration, the options, the freight basis and the lead time. Paid in full before shipment, and we do not offer net 30 or purchase order terms. Freight is quoted after the crate is measured, never charged at checkout.
BUILT HERE, AND WHAT COMES WITH IT
- N.B. Oler holds the ASME U stamp. The pressure vessels are welded in our own shop in Bend, Oregon.
- Every stainless part is fabricated here. Gaskets, filter cartridges and filter socks are purchased parts and are not represented as ours.
- Most companies selling extraction equipment are consultants who run these systems. We build them, so the people who welded your vessel are the people who answer the phone.
- Certified under 3P Certz ECR-200014-R2 with Certificate of Conformance 3PC0930. Full P.E. report included for engineering review and permitting.
- Onsite training and commissioning are part of the delivery, not optional paperwork. Systems run or modified by outside consultants without retraining are the ones that come back damaged.
- In the crate: Hydrocarbon Operators Manual, What To Expect guide, onsite training and commissioning checklist, safety and process training with a certification exam and certificate, and an operators run log.
THE OPERATING ENVELOPE
The gasket sets the cold limit on this machine, not the steel.
Pick the gasket for the temperature you actually run. Viton or Buna-N takes you to -40 F (-40 C), which covers most work. PTFE or Tuf-Steel takes you to -65 F (-54 C), where the ball valves become the limit. The vessels themselves are good to -155 F (-104 C), so they are never what stops you. See choosing a gasket material.
The -40 F figure is from 3P Certz, confirmed September 2026.
Three pressure zones, and every one is rated well below what the steel calculates to.
The solid bar is the MAWP, the working pressure the vessel is certified to and the figure that governs. The lighter bar is what ASME BPVC VIII Division 1 calculates the steel to, before the working rating is set. The margin is deliberate.
Every figure is transcribed from 3P Certz report ECR-200014-R2, released 23 September 2021, not from a brochure. Design temperature is -155 F to 200 F (-104 C to 93 C) and MDMT is -155 F (-104 C).

COMMON QUESTIONS
How do I buy one?
On a written quote. The price is $160,000 and it is published so you can budget against it, but the order goes through the shop rather than a cart checkout. Call 541-330-6409 with your throughput, your room dimensions and door width, and your permit situation, and you get a quote back with the configuration, the options, the freight basis and the lead time on it.
Why is there no straight checkout at this price?
Because the configuration, the freight and your site all change what the order says. A quote gets the options, the crate and the lead time right before money moves.
What is the published MAWP?
250 psi (17.2 bar) on the vessels. Solvent jackets are 100 psi (6.9 bar) and the liquid CO2 injection line and jacket inlets are 22 psi (1.5 bar).
How much material does it hold?
9,000 g, about 19.8 lb, of dry material per run, or 16,329 g, about 36 lb, of live resin.
How cold can it run?
The system temperature range is -40 F to 122 F (-40 C to 50 C) on Buna-N or Viton gaskets, where the low end is from 3P Certz, confirmed September 2026, and -65 F to 122 F (-54 C to 50 C) on PTFE or Tuf-Steel, where the ball valves become the limit, per ECR-200014-R2. The vessels themselves are good to -155 F (-104 C), so the gasket sets the cold limit, not the steel.
What is the lead time?
20 weeks from paid order to shipment.
Do you offer net 30 or purchase order terms?
No. Systems are paid in full before they ship.
Will it fit through a standard door?
Yes. The machine is 30.25 in x 58 in x 86 in. The shipping crate is 70.5 in long x 63 in wide x 94.75 in tall, weighs 1,850 lb, and moves by LTL freight. Give us your door width when you call and we will confirm it against your building rather than a standard.
Is a chiller included?
No. Cooling is by liquid CO2, liquid nitrogen or a process chiller, and heating needs 18 to 24 kW of hot water. Those utilities are quoted separately.
Is the CRC column included?
No. The rack is built so a CRC column or a second pair of material columns can be added later without rebuilding the skid, and it goes on the same quote if you want it now.
How is it certified?
ASME Section VIII Division 1 with the U stamp, plus a third party P.E. report and 3P Certz Certificate of Conformance 3PC0930. Tell us who your AHJ is and the quote names the documents you will be handing them.
What gasket should I run?
Viton if you are running warmer than -40 F (-40 C). It seals better than Buna-N. Below that, PTFE or Tuf-Steel. Pick one material and stay with it.
How does it ship?
LTL freight, quoted and invoiced after the crate is measured. Nothing is charged for freight at checkout.
