Multi-Sensor CO2 Monitoring System Package

Expandable Commercial CO2 Safety Monitoring Designed for Today's Facilities

The CryoFX Multi-Sensor CO2 Monitoring System Package is a complete commercial carbon dioxide gas detection system engineered to provide continuous monitoring of multiple CO2 storage locations while offering significantly greater flexibility than previous generation monitoring systems.

Developed as the direct replacement for the discontinued CFX-C2M-CM-7000 Multi-Sensor System, this modular platform combines the CryoFX Central Display Unit with two professional CO2 monitoring sensors, providing centralized gas concentration monitoring, audible and visual alarm notification, programmable ventilation control, and future expansion capability from a single integrated system.

Unlike the previous fixed two-sensor package, this new generation platform is fully expandable. As your facility grows, additional compatible sensors can be added without replacing the existing control equipment, allowing the monitoring system to scale alongside your operation.

Whether protecting restaurants, breweries, wineries, beverage dispensing systems, CO2 storage rooms, laboratories, indoor agriculture, dry ice storage, food processing facilities, entertainment venues, or industrial applications, this package provides professional-grade CO2 monitoring designed for demanding commercial environments.

CFX-RAD-CDU-HS1

Central Display Unit and Horn Strobe

The CryoFX Central Display Unit (CFX-RAD-CDU-HS1) is the centralized command hub for commercial CO2 and O2 gas safety monitoring systems, providing real-time visibility of gas concentrations, alarm conditions, and historical trends from a single easy-to-read LCD display. Designed for facilities where carbon dioxide or oxygen monitoring is critical, the CDU enables personnel to quickly identify hazardous conditions, monitor multiple sensor locations, and respond immediately to potential gas leaks or oxygen deficiency events.

Ideal for CO2 storage rooms, beverage dispensing systems, breweries, wineries, laboratories, indoor agriculture, restaurants, industrial facilities, entertainment venues, and commercial applications, the Central Display Unit consolidates data from compatible CryoFX gas detection sensors into one centralized monitoring station. Audible and visual alarm indicators immediately notify personnel when programmable alarm thresholds are reached, while integrated relays allow automatic activation of ventilation equipment or communication with building fire alarm systems.

The CDU also plays an important role in helping facilities maintain compliance with applicable OSHA, NIOSH, NFPA, IFC, and NBIC safety guidelines by providing centralized monitoring, alarm notification, and continuous display of gas detection information across multiple monitoring locations.

When paired with the CFX-RAD-0102-6-HS2 or CFX-RAD-0002-ZR-HS2 sensor systems, the CDU functions as the master controller for your gas detection network, collecting real-time readings from connected sensors while displaying alarm status and system conditions from a single dashboard. As your facility grows, the system can easily expand to accommodate additional monitoring locations without replacing the entire control system.

Whether you're designing a new CO2 safety monitoring system or expanding an existing installation, the CryoFX Central Display Unit provides a scalable, professional-grade solution engineered for reliability, code compliance, and long-term facility safety.

To begin your system, simply pair the CDU with compatible CryoFX CO2 or O2 sensor units, or contact a CryoFX gas safety specialist to configure a complete monitoring solution tailored to your application.

CFX-RAD-0102-6-HS2

Remote Carbon Dioxide CO2 Storage Safety 3 Alarm

The CryoFX Remote Carbon Dioxide CO2 Storage Safety 3 Alarm (CFX-RAD-0102-6-HS2) is a professional fixed CO2 gas detection system designed to continuously monitor carbon dioxide concentrations and provide immediate notification whenever hazardous gas levels are detected. Formerly known as the CFX-RAD-0102-6, this commercial-grade safety monitor combines a highly accurate CO2 sensor with a dedicated remote display and horn strobe, allowing personnel to monitor gas concentrations from a convenient location while maintaining audible and visual alarm notification throughout the protected area.

Carbon dioxide is colorless, odorless, and can rapidly displace oxygen, creating potentially dangerous conditions in enclosed spaces. The CFX-RAD-0102-6-HS2 continuously measures CO2 concentrations and immediately alerts personnel when programmable alarm thresholds are exceeded, helping reduce the risk of overexposure while protecting employees, customers, and facility operations.

This system is ideal for restaurants, bars, breweries, wineries, beverage carbonation systems, CO2 storage rooms, dry ice storage, laboratories, indoor agriculture, cultivation facilities, food processing plants, entertainment venues, industrial facilities, and commercial applications where compressed carbon dioxide is stored, transferred, or utilized. Many jurisdictions require CO2 monitoring wherever significant quantities of carbon dioxide are present, making reliable gas detection an essential component of workplace safety and code compliance.

Unlike standard single-location monitors, the CFX-RAD-0102-6-HS2 includes a remote display unit, allowing live gas concentration readings, alarm status, and system information to be viewed away from the sensor location. This provides increased installation flexibility while improving visibility for operators, supervisors, and emergency responders.

Three programmable relays allow automatic activation of ventilation fans or communication with building automation systems and fire alarm panels during alarm conditions. The integrated 4–20 mA output further expands system integration by supporting remote monitoring and display equipment.

The modular CryoFX platform also allows your gas monitoring system to grow as your facility expands. Compatible accessories include additional remote displays, centralized display units capable of monitoring up to 12 sensors, power monitoring modules, and auxiliary horn strobe kits for larger installations.

Installation is straightforward with disconnectable cabling, included mounting hardware, and plug-in operation requiring minimal setup. For permanent commercial installations, an optional 24VDC hardwired power configuration is also available.

Important: CryoFX recommends using a surge protector with every CFX-RAD-0102-6-HS2 installation to maximize equipment protection and long-term reliability.
