CO2 Controllers

Caron Dioxide (CO2) is one of the easiest ways to accelerate plant growth. Plants grown with supplemental CO2 can produce up to 40% more flowers or fruit. A propane or natural gas CO2 generator is the most cost effective way to add CO2 to your environment. Many greenhouses use CO2 generators to boost CO2 levels safely and economically.

CO2/PPM Monitor, Integrateable Option

CO2/PPM Monitor

The PPM-1C is an extremely accurate Carbon Dioxide/CO2 sensor. It measures the exact level of CO2 in your growing area and displays this value from 0 to 5000 Part-Per-Million (PPM) on its digital readout. Even though the PPM-1c is not realized until it is connected to one of the three controllers C.A.P. has designed to work with it. When the PPM-1c is connected to either the CO2 -2, CO2 -4 or CGC-1 controller, it commands the controllers to release or produce more CO2 only when required. The timers built into the environmental controllers continue to coordinate with the PPM-1c to give you the precision control not possible with other manufacturers' CO2 control systems using only ON/OFF control. The user enters the exact level of CO2 they want to maintain (usually 1500 PPM) and enters that value directly into the PPM-1c. The PPM-1c works with any 120-volt CO2 valve or generator that is 120-volt.

CO2 PPM/Monitor Control

CO2 PPM Monitor Control

The PPM-3 from C.A.P. is the most affordable and simple CO2 controller available. Its' proven technology is very accurate at measuring levels of Carbon Dioxide in your growing area from 0 to 5000 ppm (Parts-Per-Million). Using the PPM-3 is quite simple. Just plug your CO2 device (CO2 valve or generator) into the “piggyback“ cord and it will automatically maintain the CO2 level that you specify. The PPM-3 works with any make of CO2 valve or generator that is 120 volt.

Fuzzy-Logic™ CO2 Monitor/Control

Fuzzy Logic CO2 Monitor/Control

People who need the absolute best CO2 controller available today, use the PPM-2a from C.A.P. What sets the PPM-2a apart from the competition?
Fuzzy Logic(tm)... Fuzzy Logic(tm) can be compared to a good driver. As a good driver approaches a red light, he or she applies the brakes to gradually slow down BEFORE getting to the intersection. Fuzzy Logic(tm) uses the same idea to bring the CO2 level up to the desired setting without over-shooting the desired CO2 level. The PPM-2a automatically “dials-in“ the exact parameters for your area. It learns how your grow area uses CO2 and adapts to keep the CO2 levels constant. The PPM-2a can be connected to a temperature or environmental controller, disabling the CO2 function while your exhaust fans are running to reduce CO2 waste. The PPM-2a is capable of being used to control both compressed CO2 and gas-burning CO2 generators. When used with a CO2 generator, the user can change the PPM-2a mode to ON / OFF control which eliminates the rapid cycling of the CO2 generator. The PPM-2a will control any make of CO2 valve or generator that is 120 volts.

Warranty: Warranted to be either rebuilt or replaced at the manufacturers determination for a period of three years of normal use. Modification, misuse or abuse voids this warranty.

Environmental Controllers CO2

Environmental Controllers CO2

These systems are a breakthrough in CO2 detection and control. The CDMC-6 system is designed to sample the air and learn the characteristic of your space, then make adjustments as necessary to ensure a constant level of CO2. The CDM-6000 monitor employs a passive infrared sensor which samples the air once every second and then sends the sample data to the CDDS-2 sequencer. The CDDS-2 then activates or deactivates your CO2 enrichment or venting (exhaust) equipment to maintain desired CO2 PPM. The CDDS-2 uses a sophisticated adaptive algorithm or “Overshoot Protection Logic” to learn the dynamics of the space being controlled. This allows the systems to avoid dramatic overshoots inherent to set point controllers or timed CO2 enrichment. These learned parameters are stored in the memory, even when the ‘POWER’ is off, or until you reset the unit. The CDMC-6 system offers a large LCD screen displaying the current CO2 levels in PPM. Set your desired CO2 level, ‘Hysteresis’ and ‘Elevation’ to maintain precise levels without guesswork. The CDMC-6 system can be using for enriching or venting CO2 and incorporates a photo sensor to defeat
CO2 during dark periods (Night).

CO2 -2 Temperature/Humidity and CO2 control

CO2 Temperature, Humidity and CO2 Control

Rated for 15 amps @ 120 volts.

The CO2-2 has two timers that are used to add just the right amount of CO2 without the wasteful “overshoot“ that other controllers have. One timer controls the length of time the CO2 is released and the other controls how often the CO2 is released. The result is a very efficient method of controlling CO2. It also features temperature and humidity controls which will disable CO2 injection if the temperature or humidity levels that you specify are exceeded, activating an exhaust outlet which can control ventilation equipment (air conditioner, fan, etc.) It also has a built in photo controller, which disables the CO2 function when the lights are off. The CO2-2 can be converted to PPM level accuracy with the addition of the PPM-1c CO2 sensor. 

Warranty: Warranted to be either rebuilt or replaced at the manufacturers determination for a period of three years of normal use. Modification, misuse or abuse voids this warranty.

CO2 - 4 Temperature/Humidity and CO2 Control

CO2 - 4 Temperature, Humidity and CO2 Control

Rated for 15 amps @ 120 volts.

The CO2-4 has four timers that are used to control your CO2. In addition to all the features of the CO2-2, the CO2-4 adds two additional internal timers. The “Overall Cycle timer“ allows the user to decide how long the supplemental CO2 is kept in the growing area prior to being exhausted. When the “Overall Cycle“ time expires, the CO2-4 turns ON the exhaust outlets and enables the “Exhaust Cycle Timer“, which controls the amount of time the exhaust fans will run. When complete, the cycle is reset and the CO2 cycle starts again. The CO2-4 can also be used with the PPM-1c sensor for unequalled Parts-Per-Million performance.

Warranty: Warranted to be either rebuilt or replaced at the manufacturers determination for a period of three years of normal use. Modification, misuse or abuse voids this warranty.

Complete Greenhouse Controller

Complete Greenhouse Controller

The CGC-1 is rated for 15 amps @ 120 volts. 

 

The CGC-1 Complete Greenhouse Controller controls all of the main devices required in today's modern hydroponic garden. Your garden's HID lights are controlled by a precision 24-hour time clock. Two outlets are provided for your lights. Other functions such as supplemental CO2 and hydroponic pumps are also coordinated with the time clock. Two of the outlets on the CGC-1 are for your exhaust fans or air conditioner. A built-in thermostat and humistat handle the growing area's temperature and humidity control functions.
The two pump outlets allow your water pumps to be controlled by the built in Adjustable Recycling Timer. A selector switch allows the user to determine if the hydroponic pumps are to cycle only when the lights are ON or 24 hours a day. An auxiliary NIGHT outlet is activated when the lights are turned off. It is perfect for controlling humidity at night using a dehumidifier or for a separate heater. Supplemental CO2 is coordinated to work in harmony with your exhaust fan's temperature and humidity control functions. When the exhaust fans are running, the CO2 outlet is disabled to conserve CO2. Two standard built in timers control your CO2 valve or generator. The CGC-1 can be upgraded to Part Per Million accuracy by plugging in the PPM-1c CO2 monitor.

Warranty: Warranted to be either rebuilt or replaced at the manufacturers determination for a period of three years of normal use. Modification, misuse or abuse voids this warranty.
