Safe, Fast & Efficient Botanical Extraction Equipment & Systems
COMERG has been developing the highest quality and most efficient low-pressure extraction technology since 2015. Our ATOMIC platform combines novel extraction methods based on tetrafluoroethane (TFE) to deliver superior botanical concentrates with minimum impact to the end product. Our scalable systems and turnkey solutions provide a solid foundation for your production success.
LOW-PRESSURE AEROSOL EXTRACTION
Extract high-quality full-spectrum botanical oils at room temperature using the safest and most efficient method in the industry. COMERG’s ATOMIC extraction platform provides the highest terpene and active compound retention at the lowest operating cost, suitable for flavors, fragrances, and phytopharmaceutical applications.
COMPLIANCE SUPPORT & FACILITY DESIGN
No high-pressure classified facility required. COMERG ensures regulatory compliance from the ground up – in equipment design, safety standards, and operational procedures. All systems are built to ASME, UL, and International Fire Code standards with food-grade materials.
ONSITE TRAINING & COMMISSIONING
We offer on-site workforce training and equipment commissioning to ensure the success of your new extraction facility. Training covers installation, standard operating procedures (SOPs), and method validation of final extracts. We stay until your team is producing at full capacity.
A breakthrough in liquefied gas extraction.
COMERG’s Low Pressure Extraction technology combines novel methods based on tetrafluoroethane (TFE) — a solvent often overlooked for historical reasons, but with measurable advantages over CO₂.
- Inert & residue-free. TFE only decomposes under extreme conditions, leaving nothing in the end product.
- Lower CapEx and OpEx. Critical pressures and temperatures are well below CO₂, enabling cheaper, smaller apparatus.
- Higher polarity than CO₂. Better selectivity for sensitive aromatics with far less material degradation.
- Produced at scale. High purity TFE is widely available, keeping solvent costs predictable.
From volatile aromatics to pharmacological actives.
Universal extraction across botanical families. The non-polar TFE solvent at low and moderate pressures selectively pulls flavor and aroma compounds — what we call hash resin.
Fragrants
Damask rose · Lavender — preserved native scent with natural fixation.
Flavours
Anise, cardamom, cumin, coriander, ginger, oregano, rosemary — replace traditional spice 1:25 to 1:500.
Emollients
Grape seed · Dog rose · Cottonseed — Omega-3/6/9, vitamin E, polyphenols.
Fruit Extracts
Raspberry · Blueberry — anthocyanins, ellagitannins, kaempferol, quercetin.
Phytopharmacy
Active intermediates · primary extract purification · refining of crude extractions.
TFE vs CO₂ — the numbers.
Same goal, very different physics. Here’s why low-pressure TFE extraction changes the economics for botanical processors.

From fragrance houses to pharmaceutical intermediates — facilities running COMERG technology across three continents.
“We replaced our CO₂ line with the COMERG ATOMIC system two years ago. The rose damascena extract quality is simply incomparable — the native scent retention is something we have never achieved with supercritical CO₂ at any pressure setting.”
“The 1:500 replacement ratio for oregano is not marketing — we verified it in our production runs. We now use a fraction of the raw spice we did before. The CapEx payback was under 18 months.”
“No residue. No heat degradation. That’s what we need for pharmaceutical-grade intermediates. The COMERG team provided engineering support from initial design through GMP compliance sign-off. Excellent.”
