What is ‘Intrinsically Safe’?
Alicat's IS-Max mass flow and IS-Pro pressure instruments are designed to be intrinsically safe.
The term intrinsically safe refers to a safety concept applicable in hazardous environments. In essence, an intrinsically safe device is one that does not generate sufficient heat or electrical current to ignite flammable gases or vapors in its vicinity.
Whether operating in an environment where hazardous gases are always present (class I div 1), or only during unusual situations (class I div 2), it is advisable, if not mandatory, to utilize the equipment that is intrinsically safe.
Supported Applications
Alicat has cultivated a cooperative atmosphere to develop custom solutions for essential processes through close collaboration with the clients. Below are some of the industries.
Gas Chromatography and Analysis Labs
GC users and manufacturers both rely on Alicat IS devices for automated, low-maintenance backpressure regulation and accurate delivery of carrier gases, leading to nearly perfect Gaussian peaks, reduced peak splitting, and significantly clearer data.
Benefits of IS‑Max and IS‑Pro for Chemical Analysis
- Data logging facilitates simpler troubleshooting and diagnostics
- There is no need for manual adjustments based on operating conditions
- Digital communication enables devices to be monitored (or controlled) from outside the hazardous area
Hydrogen Electrolysis and Fuel Cell Test Stands
Obtain dependable data while ensuring safety during the electrolysis or fuel cell testing. IS-Max provides multivariate control and relative humidity sensing for PEM and fuel cell test stands, offering data and control with a reduced number of instruments.
Benefits of IS‑Max and IS‑Pro for Hydrogen
- Dew point measurement for managing condensation
- Scripting capabilities to swiftly modify test parameters
- Flow visualization and data logging tools seamlessly integrate with laboratory software
Chemical Analysis and Environmental Monitoring for Oil and Gas
Optimize CEMS and sample conditioning systems to reduce safety risks in Class I Division 1 areas. Integrate online sampling by managing backpressure while monitoring mass flow, temperature, and additional parameters. The meters and controllers are intrinsically safe, thereby removing the necessity for purge gases or explosion-proof enclosures.
Benefits of IS‑Max and IS‑Pro for Analyzers & Environmental
- IP66 ingress protection suitable for analyzer shelters, environmental monitoring, or shaded outdoor locations
- Valve usage information for enhanced preventive maintenance cycling
- Scripting and remote control/data collection functionalities
