CHARTS SPECIFIC TO THE ELECTRA-AIR MODELS
This chart will give you minutes of operation required for areas and models shown. Top row of the chart represents the cu. ft. of area
(Length x Width x Height) in the enclosure. Left column is model size. Model numbers represent maximum CO2 output per hour in cubic feet
(CD-28 = 28 cu ft/hr). Example: A CD-28 will take 3 minutes to produce a CO2 level of 1200 ppm in a 1000 cu. ft. enclosure. Highlighted
areas indicate optimum range for each model however that is subject to many variables.
Large greenhouses logically require longer charge times and multiple units may be necessary. The CD-42 takes 1 min. in an 800 cu. ft. area.
Therefore a 8,000 cu. ft. area would be 10 X 1 = 10 min. to charge to 1000 ppm. 16,000 cu/ft would take 20 minutes. For this application
this may be an acceptable charge time. 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
an optimum charge time. Try not to exceed twenty minutes when possible although this is not always practical in very large spaces. Your
microclimate will need to be recharged every one to four hours depending on how much atmosphere is lost due to natural convection or plant
Below is the information for our Electra model now discontinued. They were discontinued only because we came out with the new IR model.
