LABORATORY SAFETY
Beyond Filtration: The Missing Layer of Control
Ensuring laboratory safety does not end with filtration. The CrumaVOC sensor for filtration cabinets enables real-time monitoring of residual volatile organic compounds (VOCs) in the filtered air recirculated back into the laboratory, providing an additional layer of control that is objective and verifiable.
Specifically designed for integration into Cruma filtration cabinets, CrumaVOC enhances user protection, facilitates regulatory compliance, and provides peace of mind for laboratory managers.
The Hidden Problem
Without active monitoring, filter saturation remains invisible—until it’s too late.
Traditional indicators simply don’t reflect the real concentration of VOCs in the air.
The Real Risk
When you can’t measure it, you can’t control it.
Undetected VOCs can expose your team to harmful vapors, compromise regulatory compliance, and undermine trust in your laboratory safety systems.
The CrumaVOC Advantage
Stay ahead of risk.
Act with certainty.
Protect what matters.
CrumaVOC transforms your filtration system into an intelligent safety solution—so you’re not just filtering air, you’re controlling it.
ACTIVE CONTROL
Why is a VOC sensor essential in filtration cabinets?
Volatile organic compounds are not always detectable by smell or visible to the user. Under certain conditions, they can partially pass through the filtration system without generating any clear warning signs.
Early Detection
Identify filter saturation before it impacts air quality.
Continuous Protection
24/7 monitoring without relying on manual inspections.
Regulatory Compliance
Automatic documentation for audits and certifications.
Filter Cost Optimization
Replace filters only when needed, not based on fixed schedules.
ACTIVE CONTROL
VOC Sensor Integrated into Cruma Filtration Cabinets
CrumaVOC is a volatile organic compound (VOC) sensor specifically designed for filtration cabinets handling gases. It integrates natively into the Cruma cabinet control system, adding an extra layer of safety.
Native Integration
Directly connected to the cabinet’s electronic system, with no additional installation required.
Alert System
Three alert levels (visual and acoustic) based on detected VOC concentration.
TECHNOLOGY
How does a VOC sensor work?
Catalytic Detection
The sensor uses catalytic detection technology that reacts in the presence of volatile organic compounds, generating an electrical signal proportional to their concentration.
Continuous Monitoring
Constant sampling of the air passing through the filter, with real-time analysis and historical data logging.
Electronic Integration
Direct communication with the cabinet control system to trigger alerts and, if required, automatically stop operations.
High-sensitivity VOC sensor
User-configurable progressive alarm system
Stable signal performance across temperature variations
Factory-certified calibration

SIGNAL STABILITY VS TEMPERATURE
The sensor signal remains stable within the operating range of Cruma filtration cabinets. As shown in the graph, it exhibits minimal drift between 10°C and +55°C, without affecting detection performance.
This stability is essential to ensure alarm reliability, as it prevents environmental conditions—such as temperature fluctuations in the laboratory—from influencing the measurement of chemical compounds.
FREQUENTLY ASKED QUESTIONS
FAQs
Does the CrumaVOC sensor detect all chemical compounds?
CrumaVOC detects most volatile organic compounds (VOCs). For applications involving specific compounds or inorganic gases, please consult our technical team to select the optimal configuration.
Is it possible to install CrumaVOC on existing cabinets?
Yes, CrumaVOC can be installed as a retrofit in existing Cruma cabinets from the Classic and Plug&Play ranges. The installation is carried out by our technical service and does not require any structural modifications.
How often does the sensor require calibration?
The sensor is factory calibrated and maintains its accuracy throughout its lifetime under normal operating conditions. We recommend annual verification as part of the cabinet’s preventive maintenance.
What happens when the sensor detects high VOC levels?
The system triggers visual and acoustic alerts based on the detected level. Optionally, it can be configured to stop air recirculation or activate additional safety protocols.
Can the sensor data be exported?
Yes, CrumaVOC records historical data that can be exported for analysis, audit reporting, or integration with laboratory management systems (LIMS).
