TechGrow 4LP CO2 Generator – 4 kW and 0.9 kg CO2/h, propane-powered, for rooms up to 90 m³

TechGrow 4LP CO2 Generator

4 LPG/propane burners CO2 generator, with electric ignition and no pilot light. Produces 0.9 kg of CO2 per hour with a gas consumption of 0.3 kg/h, and covers up to 90 m³. It is the system with the lowest cost per kilo of CO2 in the catalog.

🔴 Mandatory warning: every kW of generator is 1 kW of heat

This equipment has 4 kW of power. That means it adds 4 kW of heat to your room, because all the energy from combustion ends up in the air. In a small cabinet it is simply unfeasible: it spikes the temperature, forces you to increase the extraction, and the extraction expels the CO2 you just generated. You end up burning gas to heat the room.

Combustion only makes sense in rooms over 30 m³ with controlled climate, where there is already cooling capacity to absorb that heat.

🔴 Do not use it without a controller

The manufacturer requires not to use the generator without reliable CO2 measurement, that is, without a controller with an NDIR sensor. Without control, you either fall short or reach dangerous concentrations. The generator is half the system; the controller is the other half.

No pilot light: less gas and more safety

A permanent pilot light consumes gas 24 hours a day and is a constant risk point. The 4LP electric ignition only turns on when the controller asks for it. The tip-over protection cuts the gas if the equipment falls off its mount or tilts, and the acoustic alarm alerts you to an ignition failure.

⚠️ Safety: CO2 is not harmless

CO2 at high concentrations is dangerous for people. Normal air is around 420 ppm; an enriched room operates at 1,200-1,500 ppm and above about 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 first. Cut the supply, extract for a few minutes and enter afterwards.

And since it is a gas-powered piece of equipment: install it according to the manufacturer's instructions, periodically check the hose and connections, respect the safety distances around the burner and do not work alone in a closed room with the equipment running. An independent CO2 detector is highly recommended.

Is it your step?

• Less than 2 m³: no. Passive consumable.
• 2-10 m³: large consumable or disposable bottle.
• 10-30 m³: NDIR controller + compressed bottle, which does not heat.
• More than 30 m³ with controlled climate: here yes, propane combustion is the only option with a truly low cost per kg of CO2.

Note on weight

Some distribution sheets give 0 kg for this reference, which is obviously a catalog error. The weight we apply is an estimated shipping weight and realistic for the equipment with its accessories.

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 is larger than 30 m³ and can absorb the unit's 4 kW of heat.
2. Hang the generator using the included suspension chain, maintaining the required safety clearances around the burner.
3. Connect the propane hose with regulator to the tank and check all connections with soapy water.
4. Power the unit with the included 12 VDC power supply and verify that the gas pressure is 11" WC.
5. Connect the generator to a CO2 controller with a sensor: the manufacturer requires that it not be used without reliable monitoring.
6. Turn off the supply and ventilate the room for several minutes before entering; do not work alone while the unit is operating.
