Delta Separations, ExtractionTek & Pinnacle Stainless Parts and Service — Now Under One Roof

If you run a Delta Separations CUP system, an ExtractionTek Stainless hydrocarbon extractor, or Pinnacle Stainless ethanol processing equipment, you've probably noticed that finding OEM parts and service hasn't always been straightforward. Brand transitions, corporate mergers, and shifting websites have left many operators unsure about where to go when they need a replacement gasket, a control board, or on-site technical support.

The answer is FluxWerx Manufacturing. FluxWerx is the official OEM behind all three legacy brands — Delta Separations, ExtractionTek Stainless (ETS), and Pinnacle Stainless — and they provide full parts, service, upgrades, and technical support for every system these companies ever produced. Here's what extraction operators need to know.

What Happened to Delta Separations, ExtractionTek, and Pinnacle Stainless?

The three brands share a connected history rooted in Colorado's extraction equipment manufacturing community. ExtractionTek Solutions was founded in 2011 and produced the ETS 1300, widely regarded as the first commercially sized, peer-reviewed closed-loop hydrocarbon extraction system brought to market. Pinnacle Stainless operated as an ASME-certified fabrication facility specializing in ethanol-based extraction and processing equipment. Delta Separations, based in northern California, developed the CUP Series — a centrifuge-based ethanol extraction platform that became one of the first systems to achieve UL/CUL 1389 certification and ISO 9001 compliance.

In 2021, ExtractionTek Solutions and Pinnacle Stainless merged operations under the name ExtractionTek Stainless. The combined company later acquired the Delta Separations product line. That organization has since evolved into FluxWerx Manufacturing, which now operates as the single OEM entity responsible for all three brands. FluxWerx is headquartered in Wheat Ridge, Colorado, and is led by Stephen Mueller (founder and former CEO of Mile High Labs) and Zach Harris (founder and former CEO of Pinnacle Stainless).

What Parts and Service Does FluxWerx Provide for Legacy Extraction Equipment?

FluxWerx maintains the original engineering documentation, fabrication tooling, and design files for all systems produced under the Delta Separations, ETS, and Pinnacle Stainless brands. That means they manufacture exact-spec OEM replacement components — not aftermarket approximations. Their service and support capabilities include:

• Replacement parts and components. Gaskets, seals, valves, tubing, filtration assemblies, heat exchangers, pressure vessels, and electronic control components — sourced or fabricated to original specifications.
• Preventive maintenance and repair. Scheduled maintenance programs and on-demand repair services to keep systems running within spec and minimize unplanned downtime.
• Remote troubleshooting and on-site technical service. FluxWerx's technical team can diagnose issues remotely and dispatch field service technicians when hands-on work is required.
• System upgrades and modernization. Automation integration, throughput optimization, compliance updates, and component refurbishment for operators looking to extend the life and performance of their existing equipment.
• Parts availability. FluxWerx maintains in-stock parts with overnight shipping available for most standard components.

Which Legacy Systems Does FluxWerx Support?

The table below summarizes the three legacy brands, their primary equipment lines, and the type of support available through FluxWerx.

FluxWerx also designs and manufactures new process systems for cannabis extraction, pharmaceutical manufacturing, and food and beverage production — so if your facility is outgrowing its current equipment or planning a new build, they can engineer a complete solution from the ground up.

Why OEM Support Matters for Extraction Equipment

Running extraction equipment without access to OEM parts and qualified service creates real operational risk. Aftermarket gaskets, seals, and fittings that don't meet the original pressure rating or material spec can introduce safety hazards in a C1D1 or C1D2 classified environment. Out-of-spec components can also compromise extract quality and system throughput.

From a compliance standpoint, OSHA's Process Safety Management standard (29 CFR 1910.119) and state cannabis processing regulations typically require that pressure vessels, piping, and safety-critical components meet documented engineering standards. OEM parts manufactured to the original ASME, UL, and 3-A sanitary specifications satisfy this requirement without additional validation work. FluxWerx holds ASME U, UM, and R stamps and maintains peer review by professional engineers licensed in all 50 states.

Your Equipment Needs Service — and Your Lab Needs Solvents

At Cannagas Supply, we don't sell extraction equipment — that's not our lane. What we do provide is everything that goes through it: high-purity hydrocarbon solvents (butane, propane, isobutane, custom blends), 200 proof ethanol and isopropyl alcohol, filtration media (silica 60A, B80, activated alumina), nitrogen, CO₂, and dry ice. When your ETS 1300 is back in service after a FluxWerx maintenance call, Cannagas Supply is the team that makes sure you've got the solvent and media to run it.

We work alongside equipment manufacturers and service providers like FluxWerx because our customers' operations depend on having both reliable equipment and reliable supply. If you're running a licensed extraction facility anywhere in the U.S. and need solvents, gases, or filtration media, Cannagas Supply offers local delivery in over a dozen states and rapid nationwide shipping.
