iGS-LP4X and iGS-LP8X; iGS-NG4X and iGS-NG8X

12,000 or 24,000 BTU with Heat Exchanger Liquid Propane or Natural Gas CO₂ Generator

DICONTINUED

Features

Made of aluminum: 50 % lighter than steel, durable (no rust)
Safe, easy to use and highly energy efficient
Safety panels surfaces to avoid burning at the touch
Safe electronic pilot: no manual starting button nor continuous flame
Internal electronic control to avoid excessive heating and to turn off the unit in case of tipping over
Warranty one (1) year. Periodic maintenance by the user is required (tool included).
Heat exchanger helps keep a cooler temperature inside the greenhouse or grow room without affecting the CO₂ and humidity levels
Connect to heat exchanger 6 inches diameter flexible or rigid ventilation tubing and use a fan to exhaust heat (2 metal sheets adapters included)
Heat exchanger may be ducted to supply heat to living space (fan suggested) without introducing CO₂
D: 16.5" - H: 20.5" - W: 9.5"
WARNING FIRE HAZARD GENERATOR TOP AT HIGH TEMPERATURE:Maintain at least an 18 inches (45 cm) distance between the top of the generator and the ceiling or any other combustible material to avoid causing fire

WARNING
FIRE HAZARD

GENERATOR TOP REACHES HIGH TEMPERATURE

Install and maintain at least an 18 inches (45 cm) distance between the top of the generator and the ceiling or any other combustible material to avoid causing fire

Number of CO₂ PLUG'n'GROW generators required to attain 1,500 ppm in 3-5 minutes, depending on your room size and volume:

Lab-tested validated data measured in a room at 86°F (30°C); initial CO₂ concentration 400 ppm; at sea level; air tight; without plants. Temperature, initial CO₂ concentration and altitude affect time needed to attain CO₂ levels. Reaching an expected concentration is longer with a high plant density, and in a room with unsealed openings.

Output measured at 89.6°F (32°C), relative humidity 32%, sea level and flow provided by squirrel-cage fan. Fan type, air flow, inlet air temperature, air humidity and altitude substantially impact heat exchanger outputs. The colder the inlet air, the better will be your heat exchanger output.

Useful Tips

Plug CO₂ generator sense cord to a CO₂ controller like iGS-061, iGS-100 or iGS-220 to control CO₂ concentration in your grow room or greenhouse.
To control many CO₂ generators with the same controller, you can plug a power strip in the controller outlet and plug up to 5 CO₂ generators in the power strip
Cool this generator by drawing air from outside through the sealed heat exchanger without venting out the CO₂!
