Overview
The document provides technical specifications and operational details for the CO₂ system used in climatic chambers by FDM Environment Makers. It outlines the components, functionality, and safety features of the system, as well as options for customization.

CO₂ System Specifications
The CO₂ system is designed to control CO₂ levels within a chamber, ranging from ambient values up to 20% by volume. It includes a proportional valve, a CO₂ probe, and a controller integrated into the chamber's system. The system operates without the need for an air inlet and maintains a CO₂ flow rate of approximately 0.2 m³/h at 0.5 bar pressure.

CO₂ Probe Details
The CO₂ probe uses IR technology and provides measurements with varying accuracy levels depending on the concentration range. It includes a calibration certificate and offers long-term stability and temperature compensation features.

Alarm and Safety Features
The system is equipped with visual and audible alarms for CO₂ levels, including threshold and maximum CO₂ alarms. An extended safety system can halt CO₂ input if room levels exceed 2500 ppm, ensuring human safety.

Chamber Specifications
Chambers range from 140 to 2300 liters in volume, with adjustable temperatures from -25°C to +70°C and humidity levels from 10% to 98%. They feature programmable controllers, internal ventilation, and alarms for temperature and humidity.

Customization Options
Options include systems for reducing CO₂ levels, nitrogen injection for lower CO₂ levels, and various CO₂ regulation systems with different ranges and controllers. Customers must provide a CO₂ cylinder and pressure reducer for installation.

Conclusion
The document outlines a comprehensive CO₂ control system for climatic chambers, emphasizing precision, safety, and customization to meet specific testing requirements.
