Lowtemp Industries: Complete Guide
One Brand. Every Step of the Solventless Process.
Most equipment brands solve one piece of solventless extraction — a press, a washer, or a bag set. Lowtemp Industries builds the entire chain: purpose-engineered hardware for washing, sieving, pressing, chilling, and controlling, all designed to communicate and scale together. That integration is what separates a Lowtemp lab from a collection of components.
Modular Architecture That Grows With Your Operation
Lowtemp's product philosophy centers on modularity — the ability to upgrade without starting over. Every piece of hardware connects into a larger system rather than locking operators into a single configuration.
- Press-and-Scale Architecture: The Medusa System starts at two 4x7 presses and scales up to four combined units delivering 80 tons of pressure — the same platform, more throughput, without retooling the workflow. The LT4 Heat and Pressure Controller adds dual-zone temperature management, real-time pressure mapping, and recipe storage to lock in repeatable results across every run.
- Automated Sieving Eliminates Bubble Bags: The AutoSieve Collection System replaces manual bubble bag filtration with a vibratory stainless steel sieving stack across five precisely sized micron screens (220, 160, 120, 90, and 45 microns). Labor drops. Grade separation sharpens. The process runs consistently without an operator hovering over a bag set.
- Closed-Loop Water Management: The Nest Recirculation Collection Tank captures and recirculates wash water through a closed-loop system, reducing both water consumption and the energy cost of repeatedly chilling fresh supply. It connects directly to the Osprey washers, turning the hash washing station into a self-sustaining circuit.
Matching the Right Lowtemp Setup to Your Scale
The right Lowtemp configuration depends on batch size, wash frequency, and whether the operation is building toward commercial volume or refining a boutique craft output.
- Craft and Small-Scale Producers: The Mini Lab Starter Bundle delivers a complete, turnkey entry into solventless extraction — pairing the Mini Osprey 2.0 washer and a V2 rosin press into a single purchase that takes fresh-frozen material to finished rosin without sourcing each component separately. It's the fastest path from zero to a functioning solventless workflow.
- Licensed and Commercial Operators: High-volume facilities pair the Osprey 75-gallon washer with a Medusa 4-press configuration for production-scale throughput. The Osprey handles batches up to 21,000 grams of fresh-frozen material; the Medusa meets that output with matched pressing capacity. This combination anchors a professional extraction lab.
- Infrastructure Tip: Any commercial washing operation benefits from pairing the Osprey with the 300 Gallon Chilled Water Skid System. It delivers 300 gallons of 35°F water on demand — eliminating the ice management and temperature drift that degrade hash quality mid-wash. Also browse the Solventless Wash Vessels collection for the full range of compatible infrastructure.
Running a Lowtemp Lab at Its Ceiling
Even best-in-class equipment underperforms without dialed-in process discipline. These operational principles apply directly to Lowtemp systems.
- Use Recipe Storage to Lock In Quality: The LT4 controller's recipe-saving function isn't a convenience feature — it's a consistency tool. Log the temperature, pressure, and duration settings for each cultivar after finding the peak yield window, then recall that recipe every run. Batch-to-batch variation in extract quality almost always traces back to manual settings drift, not the press itself.
- Manage Wash Water Temperature Before the Run: Hash quality degrades sharply when wash water climbs above the low 30s Fahrenheit. Pre-chill water to 35°F using the Chilled Water Skid before the washer cycle begins, not during. Starting cold and maintaining cold through the run consistently outperforms attempting to correct temperature after agitation starts.
- Stage Sieving With the AutoSieve: Running material through the full five-screen AutoSieve stack produces distinct grades in a single automated pass. Resist the impulse to blend grades post-collection — separating by micron screen preserves the ability to price and market each grade individually, which compounds revenue per pound of input material over time.

Frequently Asked Questions
What is the difference between the Lowtemp V2 single press and the Medusa System?
The V2 single-press models — available in 3x5 and 4x7 plate configurations — are standalone 20-ton hydraulic presses suited for boutique or personal-scale rosin production. The Medusa System links multiple V2 4x7 presses together under shared pump and controller infrastructure, scaling combined pressure from 40 tons (2 presses) up to 80 tons (4 presses) and processing capacity to match. The Medusa platform uses the same press units as the single models, so operators who start with a standalone V2 are already familiar with the hardware when they scale up.
What does the Lowtemp LT4 controller add over the standard controller?
The LT4 Rosin Press Controller upgrades the extraction workflow with dual-zone heat control for precise, even temperature distribution across both plates, real-time pressure mapping, an integrated timer, and extraction recipe saving. Operators can log optimal settings for specific cultivars and recall them exactly in future runs, eliminating the manual tuning that causes batch-to-batch inconsistency. Over-the-air firmware updates keep the controller current without physical service visits.
What is the capacity difference between the Mini Osprey 2.0 and the Osprey 75-gallon washer?
The Mini Osprey 2.0 is a 30-gallon stainless steel washer with a compact 28x22-inch footprint, capable of processing up to 9,000 grams of material per run — suited for craft producers and small commercial operations. The Osprey handles 75 gallons and processes up to 21,000 grams of fresh-frozen or 4,200 grams of dry material per batch, making it the production-scale choice for licensed facilities with continuous throughput requirements. Both feature precise temperature control and WiFi connectivity.
How does the AutoSieve Collection System replace bubble bags?
The AutoSieve uses a vibratory stainless steel sieving stack with five precisely sized screens (220, 160, 120, 90, and 45 microns) to automatically separate and grade hash trichomes as they exit the washer. Unlike bubble bags, which require manual filling, agitation, and draining at each micron grade, the AutoSieve completes the full separation process in a single automated pass. This reduces labor significantly, eliminates the variability of manual technique, and produces cleaner grade separation. The Mini AutoSieve is sized for the Mini Osprey 2.0, while the full AutoSieve pairs with the 75-gallon Osprey.
What does the Nest Recirculation Collection Tank do, and who needs it?
The Nest Recirculation Collection Tank (85-gallon capacity) captures wash water after it exits the sieving system and recirculates it back through the washer in a closed loop. This eliminates the need to continually supply and chill fresh water between batches, cutting both water consumption and the energy cost of repeat chilling. It's most valuable for commercial operations running multiple consecutive batches, where the time and cost of water management otherwise compounds across a production day. The Mini Nest Water Recycle Kit performs the same closed-loop function specifically for the Mini Osprey 2.0.
Why does Lowtemp recommend the 300 Gallon Chilled Water Skid System alongside the Osprey?
Consistent wash temperature — specifically maintaining water at or near 35°F throughout the entire wash cycle — is one of the most significant variables in hash quality. Ice management is labor-intensive, inconsistent, and introduces temperature fluctuations mid-run as ice melts. The 300 Gallon Chilled Water Skid System uses an 18,000 BTU chiller with a food-grade tank to deliver 300 gallons of 35°F water on demand, eliminating ice entirely. For commercial facilities running the Osprey at volume, the skid system removes the bottleneck of ice procurement and maintains wash quality across every batch in a production day.
Is the Lowtemp Mini Lab Starter Bundle a good entry point for new solventless operators?
Yes. The Mini Lab Starter Bundle is specifically designed as a complete turnkey package that takes operators from fresh-frozen material to finished rosin without the complexity of sourcing and matching individual components. It pairs the Mini Osprey 2.0 washing machine with a V2 rosin press, covering both the hash washing and the pressing steps of the solventless process. For producers who want to start with a professionally integrated system rather than assembling a lab piecemeal, the bundle reduces the initial equipment decision to a single purchase.
Can Lowtemp presses and washing machines be used for non-cannabis solventless extraction?
Yes. Lowtemp's rosin presses apply controlled heat and pressure to any botanical material, and producers working with herbs, botanicals, and non-cannabis plant matter use the V2 platform for solventless extraction across a range of applications. The hash washing machines and AutoSieve systems are also effective with other trichome-bearing plant material processed via ice water extraction. The stainless steel food-grade construction across the washing equipment makes cross-application use straightforward from a sanitation standpoint.
