Over a mile of tubing in 5 of our 8”x 48” heat exchangers! That’s a whopping 74,632 square inches — or roughly 518 square feet of stainless heat exchange surface area. I really enjoy using ChatGPT for the most outrageous and in-depth configurations and metrics for our components. What a great way to learn about your own products and learn new ways to articulate their value to your clients. How many pounds per min could you recover with that much surface area? How many KW of heat and cooling would you need? subzeroscientific.com

Is Distillation Dead? And how can Subzero’s Dominator and Einstein falling film evaporators help your isolate program? For years, distillation has been the go-to method for purifying cannabinoid extracts — turning dark, crude oil into a light, golden concentrate. But in today’s market, distillation is rapidly becoming obsolete. It’s slow, costly, and wasteful compared to modern crystallization-based workflows. Traditional extraction techniques like ethanol and CO2 tend to pull fats, sugars, chlorophyll, and other impurities along with cannabinoids. To clean this up, processors run multiple distillation passes, often decarboxylating THCA into THC in the process. Each pass adds complexity, labor, and equipment cost — while also sacrificing over 50% of the original oil mass. Crystallization is changing that. Hydrocarbon extraction (with butane or propane) can selectively capture cannabinoids and terpenes while avoiding many contaminants upfront. From there, THCA can be crystallized into nearly pure isolate — bypassing distillation entirely. These crystals can be used directly or decarboxylated into ~99% pure THC oil, all without multi-stage columns, wipers, or endless cleanup. This is where Subzero’s Dominator and Einstein falling film evaporators fit in. Before isolation, solvent recovery is critical. Our FFE systems are purpose-built to handle this step with unmatched speed and efficiency. By applying gentle heat and ensuring minimal residence time, the Dominator and Einstein remove the bulk of solvent from hydrocarbon extracts without degrading sensitive cannabinoids or terpenes. This leaves you with a terpene-rich, supersaturated mixture — the perfect starting point for THCA crystallization. Whether you’re scaling up isolate production or looking to ditch distillation altogether, Subzero’s FFE tech keeps your workflow fast, clean, and cost-effective. Bottom line: distillation isn’t just outdated — it’s unnecessary. With selective extraction, fast solvent recovery, and high-yield crystallization, isolate production is now simpler and more profitable than ever.

Subzero Scientific delivers high-performance cannabis extraction systems designed for uptime, speed, and simplicity. While others over-engineer, overcharge, and over-promise, Subzero builds extraction tools that work—day in and day out—with minimal ancillary equipment, minimal labor, and maximum results. “We’re not here to look complex. We’re here to run.” “When failure isn’t an option, simplicity is strength.” Subzero’s passive butane falling film recovery system “The Dominator” was engineered to eliminate the weak points that plague conventional extractors—no pumps to break, no complex programming to fail, and no surprise equipment lists. Just heat, chill, and flow. Operators who switch to Subzero report: -Faster recovery times -Cleaner design -Lower operating costs -One-person operation -Less downtime, fewer repairs “We get it—you bought the promise. What you got was a project.” At Subzero, we’ve been seeing a wave of frustrated operators returning to us after trying the over-complicated systems that were supposed to be ‘turnkey. We welcome you back, with the tools you actually needed the first time. “No ego. No fluff. Just proven extraction performance.” “Elegantly Engineered. Brutally Reliable.” Let’s show you what a real extraction system looks like in operation. Book a demo or consultation and see the simplicity for yourself.

It hits different buying from a company that makes their products and not just resells other people’s products. There’s nothing wrong with being a reseller, just saying it hits different having a lifetime guarantee on your fabricated products. ???❄️
