Preserve Terpene Profiles & Maximize Extract Quality
Extraction is a thermal battle. Every degree above optimal processing temperature cascades into chemical degradation—myrcene evaporates, limonene oxidizes, and your premium concentrate becomes mid-grade. Recirculating chillers eliminate this variable by circulating refrigerated fluid through your equipment's condenser coils, maintaining exact setpoints regardless of ambient conditions or load fluctuations.
Why Laboratory-Grade Temperature Control Matters
Commercial extraction demands repeatability. Inconsistent cooling creates batch-to-batch variation that destroys your brand's reputation and fails compliance testing. Holland Green Science's Aquilon series uses pharmaceutical-grade PID controllers and ETL-rated refrigeration systems to deliver stability you can certify.
-
±0.2°C Precision Control: The
Aquilon Mini through
Aquilon Max maintain tighter tolerances than most laboratory freezers, preventing thermal shock that shatters crystal structures in live resin and rosin.
-
Closed-Loop Efficiency: Recirculating systems use 70% less water than once-through cooling while eliminating mineral buildup that clogs condenser plates. Your
rosin press or vacuum oven runs cleaner, longer.
-
ETL Safety Certification: Every Aquilon chiller meets North American electrical safety standards for commercial laboratory environments—critical for insurance compliance and municipal inspections.
Sizing Your Chiller to Your Extraction Process
Cooling capacity determines throughput. Undersized chillers struggle during peak loads, forcing you to pause operations while temperatures stabilize. Oversized units waste energy and capital. Match your chiller to your equipment's BTU requirements.
-
Small-Batch Artisan Production: The
Aquilon Mini (600W cooling) supports benchtop rosin presses, small vacuum ovens, and single-condenser freeze dryers processing 1-3 lbs per day. Ideal for R&D labs and craft producers.
-
Mid-Scale Commercial Operations: The
Aquilon Midi (1300W) handles multiple extraction devices simultaneously—cool a
vacuum oven while running a freeze dryer, with 17L/min flow rate supporting 10-20 lb daily throughput.
-
Industrial-Scale Processors: The
Aquilon Max (1600W, 2500W at 10°C) features a 25L reservoir and high-flow pump for multi-room facilities. Pair it with
commercial lyophilizers or cascaded rosin press arrays processing 50+ lbs daily.
-
System Integration Tip: Chillers work in tandem with
vacuum pumps and
ultra-low freezers to create complete extraction ecosystems—coordinate cooling capacity across all heat-generating devices.
Maximizing ROI Through Thermal Management
Smart operators track cost-per-gram, not just yield. Chillers reduce three hidden expense categories that erode margins:
-
Prevent Product Degradation: Terpene loss drops concentrate value by $5-15/gram. A properly chilled rosin press maintains monoterpene content 40% better than air-cooled systems, increasing your premium-grade output ratio.
-
Extend Equipment Lifespan: Heat stress accelerates wear on hydraulic seals, vacuum pumps, and electronic controllers. Stable cooling temperatures can double the service life of press platens and condenser coils—deferring $10K+ in replacement costs.
-
Reduce Energy Waste: Recirculating chillers consume 60% less electricity than HVAC-based room cooling strategies. The Aquilon series' EC motor technology further cuts operating costs by $200-400 annually compared to older compressor designs.

Frequently Asked Questions
What's the difference between a recirculating chiller and an ice bath for extraction cooling?
Recirculating chillers maintain precise, stable temperatures (±0.2°C) throughout your entire extraction run, while ice baths fluctuate 5-10°C as ice melts. This consistency prevents thermal shock that damages delicate terpene structures. Chillers also recycle coolant indefinitely—no daily ice purchases or meltwater disposal—reducing operating costs by $50-100 monthly while delivering pharmaceutical-grade repeatability.
How do I calculate the right chiller cooling capacity for my rosin press or freeze dryer?
Add your equipment's heat load (in watts or BTUs) plus 20% overhead for ambient temperature compensation. Small rosin presses (5-10 ton) typically need 600-800W, mid-size presses (12-20 ton) require 1000-1500W, and industrial systems (30+ ton) or freeze dryers demand 1600W+. The Aquilon Mini handles up to 2000 BTU/hr, the Midi covers 4400 BTU/hr, and the Max supports 8500 BTU/hr at standard conditions.
Can I run multiple pieces of extraction equipment off one chiller?
Yes, if your chiller's cooling capacity and flow rate exceed the combined heat load. The Aquilon Midi's 17L/min flow supports simultaneous operation of a rosin press and vacuum oven, while the Max's 25L reservoir can handle a freeze dryer plus multiple auxiliary devices. Use manifold splitters with individual flow meters to balance cooling distribution across equipment. Always maintain 15-20% capacity reserve to prevent thermal lag during peak loads.
What maintenance do recirculating chillers require?
Replace coolant annually or every 2000 operating hours to prevent algae growth and corrosion. Clean the condenser fins quarterly using compressed air or soft brushes to maintain heat exchange efficiency. Inspect inlet filters monthly and replace when flow rates drop 10%. The Aquilon series uses automotive-grade ethylene glycol coolant (50/50 mix with distilled water) available at any auto parts store—budget $40-60 per annual change for the Mini/Midi, $80-100 for the Max.
Do chillers require special electrical installation or dedicated circuits?
The Aquilon Mini and Midi operate on standard 120V/15A circuits, allowing plug-and-play installation in most labs. The Aquilon Max requires 120V/20A dedicated circuit to handle its 1600W compressor draw. All models are ETL-certified for commercial use and include GFCI-compatible plugs. Avoid extension cords—direct wall connection prevents voltage drop that degrades compressor efficiency and voids warranties.
How does precise temperature control improve extraction yield and quality?
Every 5°C above optimal extraction temperature causes 8-12% terpene evaporation and accelerates cannabinoid oxidation. Chillers maintain the ideal 15-25°C range for rosin pressing and sub-zero temperatures for freeze drying, preserving volatile compounds that determine flavor, aroma, and therapeutic effects. Labs using precision cooling report 15-25% higher yields of premium-grade concentrates compared to ambient-cooled operations, directly increasing revenue per pound processed.
What's the difference between the Aquilon Mini, Midi, and Max chillers?
Cooling capacity and reservoir size scale with production volume. The Mini (600W, 7L reservoir) suits benchtop operations processing 1-5 lbs daily. The Midi (1300W, 12L reservoir, 17L/min flow) handles commercial labs running 10-20 lbs daily across multiple devices. The Max (1600W standard, 2500W at 10°C, 25L reservoir) powers industrial facilities processing 50+ lbs daily or operating large-scale freeze dryers. All three deliver ±0.2°C precision and ETL safety certification—choose based on your throughput requirements and equipment heat load.
Are Holland Green Science chillers compatible with other brands' extraction equipment?
Yes. Aquilon chillers use standard quick-disconnect fittings (3/8" and 1/2" barb) compatible with most rosin presses, vacuum ovens, rotary evaporators, and freeze dryers. The universal coolant (ethylene glycol/water mix) works with stainless steel, copper, and aluminum heat exchangers. Verify your equipment's flow rate requirements—most devices need 5-15 L/min, well within the Aquilon series' 17-20 L/min capacity. Adapters for proprietary fittings are available from your equipment manufacturer.
