Hotbox CO2 Growth Gas Generator 2.5kW


The made to order CO2 Growth Gas Generator 2.5kW burns LPG or Natural Gas, providing ideal growing conditions by controlling CO2emissions.

Controlled by an electrical solenoid valve which can be operated by a time switch set to run a few minutes each hour, the Growth Gas Generator provides the correct levels of CO2. Known as the 'Threefold Enrichment' process, it is widely used by professional gardeners during the hours of daylight to speed up photosynthesis, enhancing plant development.

Depending on the size of your greenhouse the Growth Gas Generator should burn on and off for about twelve minutes in each hour, burning roughly 0.25kg of propane in twelve hours. This should increase the amount of carbon dioxide in the air to 1000 parts per million, up from the 300ppm we breathe in as air.

With an output of 2.5kW the Growth Gas Generator will heat an area of up to 100sq ft and provide frost protection for an area up to 160sq ft.

The Growth Gas Generator is supplied with a fused 13amp plug. Not included is an electronic timer which is required to control the amount of time the appliance is switched on and off, available from the options section.

Also available is a B.S high pressure hose with two jubilee clips, supplied in 1 metre lengths; a gas low gauge, which when attached to a regulator will indicate when you need to replace the gas cylinder, and an auto changeover valve that will automatically switch from one gas cylinder to another (includes hoses, connections and full user instructions). For natural gas models a connection kit is available, screwing into the back of the heater with bayonet connector at other end.

Gas powered greenhouse heaters should only be used in well ventilated areas to ensure the CO2sensor is not set-off thus cutting out operation.
