Gas warning or gas alarm systems must be reliable at all times. When gas leakages such as carbon dioxide (CO2), carbon monoxide (CO) or nitrogen oxides (NOx) occur, quick intervention and reliable products are needed. The sensors, controllers and warning devices by MSR-Electronic effectively protect people and systems in hazardous situations when combustible or toxic gases are emitted.

Gas warning systems for garages, tunnels and loading zones

Safety from CO / NO2 / LPG


Stationary gas warning systems in garages, tunnels and loading zones are the crucial monitoring instrument of a ventilation system. It regulates the air quality in enclosed spaces and decides when to start the ventilation. Reliable application is regulated throughout Europe in the EN 50545 standard. EN 50545 - the central standard for gas monitoring in garages and tunnels - requires extensive prerequisites for gas alarm systems. The gases CO, NO2 and LPG to be monitored by means of sensor technology are defined in the standard. In addition to the type of warning, SIL monitoring is also required to EN 50271, which is referenced in EN 50545.

Gas warning systems for laboratories, research and medicine

Safety from CO2 / O2 / N2 / H2 / C3H8 / CH4 / CH2O / O3


Especially the sensitive medical, research and laboratory area must be constantly monitored in order to protect against hazardous substances. MSR gas detectors are particularly flexible to use in this respect, as all requirements can be tailored to suit individual needs. Whether individual sensors with connection to existing BMS systems or complex self-sufficient gas detection systems for large-scale laboratories with different areas. The MSR products comply with more than the general standards and regulations and can therefore guarantee the protection of employees and the safety of the plant.

Gas warning systems for beverage systems

Protection against CO2 poisoning and O2 deficiency


The sensors can be used in restaurants, breweries and fermenting cellars, breweries, wineries, beverage bottling systems, but also in CO2 extinguishing agent systems in warehouses and production halls, wherever CO2 bottles, lines and tanks are required. The DEM-06-IO-A module ensures access to enclosed spaces where CO2 leakage can occur and displays increased gas concentration in real time. Thus, safety is perfectly guaranteed.

Ripening in controlled atmosphere

Reliable monitoring of CO2 / C2H4 / C2H4O and O2 deficiency


Fresh fruit and vegetables are alive and continue to breathe after the harvest. This leads to oxygen consumption and the formation of carbon dioxide and water vapour. Keeping the products fresh means slowing down the process while maintaining the quality of the product. Gas sensors are just as important as the modern technology of the ripening chambers. They are required to permanently monitor the various gas concentrations involved in the ripening process. The sensors, controllers and warning devices from MSR-Electronic protect people and equipment effectively and monitor the system as a central point of the entire process.

Gas warning systems for refrigeration systems

protection against refrigerants


Refrigeration systems above a certain size must be equipped with a gas warning device. The requirements for gas detectors depend on the type of refrigerant and the specific application. The requirements of EN 378 and EN 14624, among others, apply here. The European
standard specifies the requirements for the safety of persons and property. MSR gas sensors are safer than the standards require and reliably protect life and system. The gas detection system from MSR-Electronic can be adapted exactly to the respective regulations (e.g. switching thresholds) thanks to flexible setting options.
