CARBON DIOXIDE (CO2)
MONITOR AND CONTROL SYTEMS

Research laboratories and universities have proven that increased levels of carbon dioxide will greatly 0improve plant growth. Plant metabolism is regulated primarily by the availability of the essential requirements - air, light, nutrients, water, humidity and temperature. If any of these basic necessities are deficient or limited, then the growth rate of your indoor plants will be limited.

CO2 combines with water, nutrients and light energy through photosynthesis to produce sugars (food). These sugars provide energy to manufacture plant tissues for new growth. When CO2 levels are inadequate or inconsistent, plant growth diminishes and reduces crop yield.

Green Air Products offers systems that monitor and control CO2 levels. When used in conjunction with our CO2 generators or bottled CO2 and the right atmospheric control equipment, indoor and greenhouse growers will see a dramatic improvement in growth, quality and yield.

THREE MODELS TO CHOOSE

SPC-1

CDMC-6

CDMC-7

 


CO2 SET POINT CONTROLLER
SPC-1

The SPC-1 is our easiest and most cost effective CO2 monitor and control system and is designed for indoor garden and greenhouses. Just set it and forget it.

The SPC-1 samples the air and determines the concentration of CO2 in PPM. Then when indicated by your set point values (desired PPM CO2 and elevation), the unit will activate CO2 enrichment equipment plugged into the piggy back cord. The SPC-1 has a fixed hysteresis (differential) of 20 PPM.

EXAMPLE: With a CO2 set point of 1000 PPM, the unit will activate (turn "ON") whenever concentrations fall below 1000 PPM and continued to control and allow your CO2 equipment to enrich your environment until it detects about 1020 PPM. The SPC-1 is a reactive CO2 controller and the PPM concentration of CO2 will float above 1020 PPM after defeating enrichment equipment (overshoot).

FEATURES

• Set and Forget; Easy to install and operate
• Durable infrared sensor
• Factory calibrated and inspected for precision performance
• Preset hysteresis (differential) of 20 PPM
• Photo Sensor to defeat CO2 enrichment at night (dark)
• Large LED display offers real-time CO2 PPM
• Orange LED to indicate when CO2 enrichment is active
• Elevation adjustment feature for improved accuracy
• Fully integrable with other atmospheric controllers or timers
• Hardy black anodized aluminum chassis resists rusting, corrosion and scratching
• Red illuminated power switch
• 14 AWG, SJTW rated piggy-back power cord
• Operates on 120 VAC at 60 Hz, 12 Amp switching capacity
• Manufactured in Oregon, USA

CARBON DIOXIDE MONITOR CONTROLLER SYSTEM

CDMC-6

The CDMC-6 system is designed to sample the air and learn the characteristics of your space, then make adjustments as necessary to ensure a constant level of CO2. The CDM-6000 works in conjunction with the CDDS-2 controller (sequencer) to effectively enrich indoor gardens and greenhouses with CO2 or reconfigured the system mode to vent excess CO2 if desired.

ENRICHMENT or VENTING MODE
The CDMC-6 can be used to operate CO2 producing (enrichment) equipment or CO2 venting (exhaust) equipment. Use the MODE button to quickly and easily switch between enrichment or venting functions. The venting mode is useful for evacuating accumulated CO2 in hospitals, class rooms, factories, conference and meeting rooms, offices, laboratories and mushroom culture facilities.

HOW THE CDMC-6 SYSTEM WORKS
The CDM-6000 samples the air then sends the sample data to the CDDS-2. The CDDS-2 then activates or deactivates your CO2 enrichment or CO2 venting (exhaust) equipment as necessary to maintain CO2 PPM based on your set point. For best results, turn off all exhaust functions and close all doors and windows during the initial 24-hour adjustment period. You must allow this 24-hour adjustment period, every time you relocate the system to a new space. After 24 hours, you can restart your exhaust functions and continue as normal.

LOCATING THE SENSOR
For best results, mount the CDM-6000 sensor in the middle of your greenhouse or indoor garden, or on a wall support structure opposite the CO2 enrichment equipment. Do not mount the sensor in the immediate vicinity of the CO2 equipment. Protect your system from foliar sprays and irrigation moisture. Corrosion resulting from these activities will interfere with the sensors ability to accurately monitor and control CO2.

OVERSHOOT PROTECTION LOGIC
In enrichment mode, the CDDS-2 employs a sophisticated adaptive algorithm “Overshoot Protection Logic” which learns the dynamics of the space being controlled. This allows the system to avoid dramatic overshoots inherent to set point controllers or timed CO2 enrichment. These learned parameters are stored in memory, even when the ‘POWER’ is off, until you reset the CDDS-2.

The graph below demonstrates the average variance in CO2 concentrations when using the CDMC-6 system with “Overshoot Logic Protections” verses timed CO2 enrichment.

Example: Enrichment Mode Set Point = 1050 Hysteresis = 50

CARBON DIOXIDE MONITOR CONTROLLER SYSTEM
CDMC-7

This CO2 monitor control system functions exactly like the CDMC-6 system and utilizes the same controller (sequencer) CDDS-2. However, the CDM-7001 monitor in this system offers the versatility of portability. You can detach to the monitor and carry it from one location to the next and make spot checks of CO2 concentrations. Please note that the monitor must be patched into the controller to actually enrich or vent CO2.

FEATURES

• Built-in Photo Sensor for enhanced control
• Easy to program and operate with adjustable hysteresis (differential)
• Programmed for overshoot protection logic
• Portable CO2 monitor display both CO2 levels and temperature
• Durable infrared sensor
• CO2 measurement range from 0-5000 PPM
• CO2 control range from 300-5000 PPM
• Easy to read LED display light will not affect plant growth
• Mode indicator LEDs
• Factory calibrated and inspected for precision performance
• Operates on 120 VAC at 60 Hz, 12 Amp switching capacity
• Built in kick-stand
• Requires 4 AAA batteries for portable operations
• CO2 gas calibration port
