VDL Propane-Powered CO2 Generator – 4 burners for 90 m³ or 8 high-output burners

VDL Propane-Powered CO2 Generator

CO2 generator powered by propane combustion, available in two power ratings. It is the system with the lowest cost per kilogram of CO2 and the only one that makes sense for large rooms, provided the climate is controlled.

The Two Models

• 4 burners: covers 90 m³.
• 8 burners: twice the power of the 4-burner model.

🔴 Mandatory Warning: Every kW of Generator is 1 kW of Heat

This must be understood before purchasing, as it is the number one cause of buyer's remorse with these units. A combustion generator adds as much heat to the room as it has thermal power: every kW burned is 1 kW of extra heat.

In a small closet, this is simply unfeasible: it spikes the temperature, forcing you to increase ventilation, which in turn expels the very CO2 you have just generated. You end up spending gas to heat the room. Combustion only makes sense in rooms larger than 30 m³ with controlled climate, where there is already cooling capacity to absorb that heat.

🔴 Do Not Use Without a Controller

The manufacturer requires that you do not use the generator without reliable CO2 monitoring, meaning a controller with a sensor. Without control, you will either fall short or reach concentrations that are dangerous for people and the crop itself. The generator is half the system; the other half is the controller.

⚠️ Safety: CO2 Is Not Harmless

High concentrations of CO2 are dangerous for people. Normal air is around 420 ppm; an enriched room operates at 1,200–1,500 ppm, and above approximately 5,000 ppm, there is a real health risk: headache, dizziness, disorientation, and, at extreme concentrations, loss of consciousness. Never enter a room with active dosing without ventilating it first. Turn off the supply, ventilate for a few minutes, and then enter.

Additional information for combustion equipment: there is a flame and a gas cylinder involved. Install the equipment according to the manufacturer's instructions, periodically check the gas connections, keep the area around the burner clear, and do not work alone in a closed room with the equipment running. An independent CO2 detector is highly recommended.

Is It Right for You?

• Less than 2 m³: definitely not. Use a passive consumable.
• 2–10 m³: a large consumable or disposable cylinder.
• 10–30 m³: NDIR controller + compressed cylinder that does not heat.
• More than 30 m³ with controlled climate: yes, propane combustion is the only option with a truly low cost per kilogram of CO2.

Transparency Note

Some distributor data sheets include an "aroma" attribute for this generator. This is a catalog error: a CO2 generator has no aroma and does not add any. We omit it.

At GrowIndustry we only work with proven quality products and trusted brands.

Every item goes through a check before shipping to make sure it arrives in perfect condition and ready to use.

Your satisfaction is our priority.

1. Before purchasing, confirm that your room exceeds 30 m³ and has sufficient cooling capacity to absorb the heat generated by the burner.
2. Install the suspended generator, maintaining the safety distances around the flame specified by the manufacturer.
3. Connect the propane cylinder with its regulator and check all connections with soapy water before the first ignition.
4. Connect the generator to a CO2 controller with a sensor: the manufacturer requires that it not be used without reliable monitoring.
5. Set the ppm target on the controller and check during the first few cycles that the room temperature remains under control.
6. Turn off the supply and ventilate the room for several minutes before entering to work; do not work alone with the equipment running.
