In the landscape of industrial safety, monitoring hazardous atmospheres is an absolute priority. Irudek, a leading company in personal protective equipment, offers an advanced range of gas detectors designed to operate in the most extreme conditions, ensuring worker protection against toxic and flammable gases, as well as oxygen deficiency.
1. Overview of the Irudek Range
Irudek devices are mainly divided into two categories: Single-gas (for a specific single hazard) and Multi-gas (for the simultaneous monitoring of multiple threats).
- SGT & SGT-P (Single-gas): Compact and lightweight devices. The SGT model is "disposable" (2-year lifespan), while the SGT-P is reusable with a replaceable sensor and battery.
- MGT (Multi-gas): Portable detector capable of monitoring up to 4 gases simultaneously. It is also available in the MGT Pump version, equipped with an integrated sampling pump for confined space sampling prior to entry.
- iGAS CO2: Specialized in carbon dioxide detection using infrared (NDIR) technology.
2. Detectable Gases and Industrial Applications
Irudek sensors cover a wide range of volatile substances. Below are the main gases monitored and their respective contexts of use:
| Detectable Gas |
Detector Type |
Main Applications |
| Oxygen (O2) |
SGT / MGT |
Prevention of asphyxiation in confined spaces or enrichment (fire risk). |
| Carbon Monoxide (CO) |
SGT / MGT |
Steelworks, garages, thermal power plants, firefighting. |
| Hydrogen Sulfide (H2S) |
SGT / MGT |
Wastewater treatment, petrochemical industry, agriculture. |
| Combustible Gases (LEL/CH4) |
MGT |
Monitoring of methane leaks or flammable vapors (LPG, hydrogen). |
| Carbon Dioxide (CO2) |
iGAS CO2 |
Food & beverage industry, greenhouses, refrigeration. |
| Special Toxic Gases |
SGT-P |
Detection of NH3 (ammonia), Cl2 (chlorine), SO2 (sulfur dioxide). |
3. Certifications and Safety Standards
Regulatory compliance is at the core of Irudek technology. Since many of these gases are flammable, the devices are certified to operate in ATEX Zones (Explosive Atmospheres).
ATEX Certification
Irudek detectors (such as the Duo Tracer or the MGT series) feature markings such as:
Ex ia IIC T4 Ga
- Ex ia: Intrinsic safety (the device cannot generate sparks or sufficient heat to ignite an explosion).
- IIC: Gas group (includes the most hazardous gases such as hydrogen).
- T4: Temperature class (maximum surface temperature of the equipment < 135°C).
- Ga: Equipment Protection Level (suitable for Zone 0, constant presence of gas).
Other Standards
- IP67: Total protection against dust and temporary immersion in water.
- IECEx: International certification scheme for equipment intended for use in explosive atmospheres.
4. Maintenance and Data Management
To ensure constant reliability, Irudek integrates simplified management systems:
- Bump Test: Quick sensor verification before use via dedicated calibration stations.
- IR Link: Infrared interface to download the event history (up to 30 alarms for single-gas and thousands for multi-gas) and configure alarm thresholds via PC.
- Multiple Alarms: Acoustic (95dB), visual (red LEDs), and vibrating alerts to ensure hazard perception even in noisy environments.
Conclusion
Irudek gas detectors represent a robust and versatile solution for those operating in critical industrial environments. From the simplicity of the SGT single-gas to the comprehensive MGT Pump multi-gas, safety is guaranteed by precise sensors and top-tier certifications.
