Thermal Control That Preserves Purity
Solventless extraction relies on temperature gradients measured in single degrees. Holland Green Science builds systems where ±0.2°C precision isn't a spec sheet claim—it's guaranteed by ETL-certified controllers and dual-stage vacuum pumps.
Laboratory Infrastructure for Serious Processors
Commercial cannabis processing requires infrastructure that scales beyond countertop solutions. HGS systems transform raw material into concentrate without compromising the compounds you're targeting.
-
Hephaestus Vacuum Ovens: The
compact 90L model purges residual solvents at pressures below atmospheric, while the
900L industrial unit handles batch processing without thermal degradation. Every shelf maintains uniform heat distribution across 200°C ranges.
-
Aquilon Chillers: Closed-loop distillation and
rosin pressing both generate heat spikes that ruin terpene profiles. The
600W Mini handles personal lab setups, while the
1600W Max maintains ±0.2°C control for high-throughput rotovaps and condensers.
-
Preseva Freezers: Winterization strips lipids and waxes from crude extract—but only when ethanol reaches -50°C to -86°C. The
Preseva Pagoma uses cascade compressor technology to hold ultra-low temperatures that entry-level freezers cannot sustain.
Choosing Your Extraction Pathway
Your processing volume and target product determine which HGS system integrates into your workflow. Entry-level operations need different capacity than licensed commercial facilities.
-
Solventless Artisans: The
Piesi 5 and
Piesi 7 deliver hydraulic pressure up to 7 tons with 2.4x4.7" plates—ideal for pressing hash or flower without solvents. Pair with
micron filter bags for maximum purity.
-
Solvent-Based Labs: The
Hephaestus 124 decarboxylates biomass at precise temperatures, while vacuum ovens purge residual ethanol or butane to meet safety thresholds below 5000ppm. Integrate
Aether vacuum pumps for 0.003mbar ultimate vacuum.
-
Pharmaceutical-Grade Processing: The
Xiros Mikro freeze-dryer preserves cannabinoid profiles through sublimation, while the
Xiros 2 scales to 10kg ice capacity with Edwards vacuum pump systems and liquid nitrogen compatibility.
Building a Lab That Scales With Your License
Commercial extraction isn't a single machine—it's a thermal ecosystem. HGS equipment integrates into processing chains where each stage depends on the previous step maintaining target parameters.
-
Closed-Loop Thermal Management: Chillers maintain consistent condenser temperatures during distillation while vacuum ovens eliminate residual volatiles. The
Aquilon Midi delivers 17L/min flow rate for mid-scale rotary evaporators.
-
Programmable Repeatability: Touchscreen controllers on Hephaestus ovens and Xiros freeze-dryers store custom protocols with team permissions and activity tracking—critical for SOPs in licensed facilities.
-
Compliance-Ready Documentation: ETL and CE certifications ensure equipment meets electrical safety standards that inspectors verify during audits. HGS systems ship with technical documentation that satisfies regulatory file requirements.

Frequently Asked Questions
What's the difference between Holland Green Science vacuum ovens and standard lab ovens?
Vacuum ovens remove air from the chamber, which lowers the boiling point of residual solvents and allows purging at temperatures that won't degrade cannabinoids or terpenes. Standard convection ovens rely on atmospheric pressure and require higher temperatures that risk thermal damage. HGS vacuum ovens maintain precise vacuum levels while providing uniform heat distribution across multiple shelf positions.
How do I choose between the Piesi 5 and Piesi 7 rosin presses?
The Piesi 5 delivers 5 tons of pressure with 250°C maximum temperature—suitable for personal extraction or small batches up to 3.5 grams. The Piesi 7 increases pressure to 7 tons with 270°C capability for slightly larger yields and denser starting material. Both use identical 2.4x4.7" plate dimensions, so your choice depends on how much force you need for optimal extraction from your specific material.
Why do I need a chiller for extraction equipment?
Extraction processes generate significant heat that degrades terpenes and cannabinoids. Rotary evaporators, short-path distillation units, and closed-loop systems all require precise condenser cooling to maintain vapor capture efficiency. Aquilon chillers circulate coolant at controlled temperatures with ±0.2°C precision, preventing thermal runaway that ruins concentrate quality and reduces yields.
What's the advantage of the Preseva Pagoma's ultra-low temperature range?
Winterization requires temperatures below -50°C to effectively precipitate lipids, waxes, and chlorophyll from crude extract dissolved in ethanol. The Preseva Pagoma reaches -86°C using cascade compressor technology, enabling faster filtration cycles and cleaner concentrate with minimal cannabinoid loss. Standard freezers cannot achieve or maintain these temperatures under repeated cycling.
Can Holland Green Science freeze dryers handle cannabis material?
Yes—the Xiros Mikro and Xiros 2 lyophilizers preserve cannabinoid and terpene profiles through sublimation, removing moisture without applying heat. The customizable shelving accommodates trays of fresh-frozen material or water hash. These systems maintain vacuum below 0.01 mbar while condenser temperatures reach -45°C, creating conditions where ice transitions directly to vapor without degrading sensitive compounds.
What vacuum pump do I need for HGS vacuum ovens?
HGS vacuum ovens require pumps capable of reaching ultimate vacuum below 0.1 mbar. The Aether Premier delivers 142 L/min displacement with 0.003mbar capability using dual-stage rotary vane design, while the Anemos oil-free pump reaches 0.008 mbar without requiring oil changes. Your choice depends on maintenance preferences and whether your solvents would contaminate oil-lubricated systems.
Are Holland Green Science systems compliant with commercial licensing requirements?
All HGS equipment carries ETL and CE certifications verifying electrical safety and performance standards. The programmable controllers provide activity logs and team permissions that satisfy standard operating procedure requirements in licensed facilities. However, specific compliance depends on your jurisdiction's regulations—consult with your state's cannabis authority regarding equipment specifications for your license class.
What warranty coverage does Holland Green Science provide?
Holland Green Science offers a limited 2-year warranty covering manufacturing defects and component failures under normal operation. The warranty does not cover operator error, abuse, or damage from improper use. Regular maintenance—including vacuum pump oil changes on Aether models and condenser coil cleaning on chillers—is essential to maintain warranty coverage and optimal performance.
