This chart is used to decide how long a tank of propane will last. This chart is fairly self explanatory
first you will look in the left column to pick a model, then follow it across to the propane tank size
you have. The number that corresponds with the two selections will be the number of hours that
you can operate the Co2 generator.

Carbon Dioxide Enrichment will dramatically increase the growth of green
plants. Green plants use carbon dioxide (CO2 ) and water in the presence of
light to synthesize organic compounds. The plant then converts these organic
compounds into elements that it can use (food). This process is called
photosynthesis. If any of these ingredients (CO2, water or light) are at levels
below what the plant can use for maximum efficiency, it will only be able to
perform at that level and no greater. Adding carbon dioxide to a growing
environment that is not receiving proper nutrients or is low on light will not
produce the desired results. Similarly, plants that are receiving plenty of
sunshine and nutrients will only perform as well as the level of CO2 will allow.
The ambient level of CO2 in the earth's atmosphere is generally between 300
and 400 ppm. Most plants receive far more water and energy in the form of
sunshine than they can use. Increasing the CO2 in the growing area will let
the plant use the excess water and energy that is stored in the leaves. The
result is a substantial increase in the growth rate of any plant that uses
chlorophyll in the process of photosynthesis. Enrichment should commence
at sunrise or when photoperiod begins and refrain during darkness hours.
The average CO2 level that is recommended is 1000 to 2000 parts per million
(PPM). The object is to maintain a constant level in the atmosphere. You can
run a small unit continuously during photoperiods or you can use a larger unit
and time it to function periodically. Where exhaust requirements are frequent,
the latter method is preferable. After the exhaust function the generator can
be cycled to replenish CO2 quickly to maintain rapid plant photosynthesis.
Use the operation time charts to determine the size of generator and the
number of minutes of operation required for the level of CO2 desired. Frequency
of recharge depends on the rate of consumption. For the greatest fuel economy
and accuracy of recharge it is recommended that the Green Air Products
CO2 Monitor Controller (CDMC) be used with all generator and emitter
systems.
** IMPORTANT **
Carbon dioxide generators operate by burning carbonaceous fuels such as
propane or natural gas. The burners used in Green Air Products CO2
generators are specially designed to maximize the production of CO2 and
minimize heat as a by-product. Green Air Products generators provide CO2
far more economically than any other means of enrichment. A constant
burning pilot is used to ignite the gas when the generator is turned on. A
thermocouple is used to monitor the pilot flame. If the pilot flame is lost, a
safety valve will close so that unburned fuel will not be released into the
enclosure. CO2 generator operations may be automatically functioned
according to actual ambient values when installed in conjunction with a CDMC
controller. This control device continually samples the level of carbon dioxide
in the growing area and functions the generator whenever CO2 levels do
not meet your predetermined values. Generators are easily installed,
dependable and efficient. Transformer included. Operates on 110VAC.
Rules For Safe Operation
•
Read and understand the information in this manual before operating the
equipment. Observe all CAUTIONS.
•
Unit should be operated in a safe, clean and ventilated area free of flammable
materials.
•
Housing becomes hot under normal operating conditions. To avoid possible
burns, never touch equipment during operation.
•
To service or repair this unit always disconnect power source and shut off
fuel supply.
•
Do not operate if gas fumes are noticed. It is recommended the fuel tank be
located outdoors or in a well ventilated area free of sparks or open flame.
•
For service or repair always send the unit back to the factory or an authorized
service center.
Never overfill propane tank. Allow room for expansion of contents due to
contrast in temperatures. It is recommended that tank be located outside the
enclosure for safest operation. A properly burning flame should burn clean
and blue and produce no toxic emissions. Remember a flame requires oxygen
to burn so adequate fresh air intake and circulation is important. Always check
for leaks after refitting.
Principals of Operation
Introduction
This chart will give you the minutes of operation required for the areas and
models shown. Top row of the chart represents cubic feet of area in the
enclosure (LxWxH) The left column is the model size. Model numbers
represent maximum CO2 output per hour in cubic feet (CD-3 = 3 cuft/hr CO2)
Example: A CD-6 will take 10 minutes to produce a CO2 level of 1000 ppm
in a 1000 cu. ft. enclosure. The area should be charged as quickly as possible
for maximum advantage. Charging the atmosphere quickly insures that the
rapid photosynthesis process will not be interrupted and the plants growth
rate reduced. Five to ten minutes is a good charge time. Try not to exceed
twenty minutes. Your microclimate will need to be recharged every 1 to 4
hours depending on how much CO2 is lost due to plant usage or drafts (leaks).
Large greenhouses logically require longer charge times and multiple units
may be necessary. The CD-36 takes 1.66 minutes per 1000 cu.ft. area to
charge to 1000 ppm. Therefore a 20,000 cu. ft. area would be 20 X 1.66 which
is 33.2 minutes. For this application that may be an acceptable charge time.
