EVIKON – Gas Detection Systems
Reliable Detection of Flammable, Toxic and Refrigerant Gases
EVIKON MCI is an Estonian manufacturer headquartered in Tartu, specialising in the development and production of measuring instruments, transmitters and detectors for gas monitoring and indoor air quality.
EVIKON offers solutions for the detection of flammable and toxic gases, carbon dioxide (CO₂), oxygen (O₂), refrigerants and a wide range of other gases and vapours, depending on the specific application requirements.
Systems can operate as standalone solutions or be integrated with ventilation, building management systems (BMS) and other safety and control systems.
How Does a Gas Detection System Work?
Gas detectors continuously measure the concentration of a specific gas in the monitored area. When the measured concentration exceeds a defined threshold, the system can activate visual and audible alarms and automatically initiate appropriate safety functions.
Depending on the application, these functions may include starting or changing the operating stage of the ventilation system, closing a gas shut-off solenoid valve, transmitting an alarm to a supervisory system or activating other control devices.
Gas detection is therefore more than an alarm function. A properly designed system enables an automatic response to increased gas concentrations before hazardous conditions develop for people, equipment or the building.
Flammable Gas Detection
Flammable gas and vapour detectors are used in areas where an explosive atmosphere may occur.
EVIKON provides solutions for the detection of methane (CH₄), propane, butane, LPG, hydrogen (H₂) and other flammable gases and vapours.
Flammable gas concentrations are generally monitored in relation to the Lower Explosive Limit (LEL). This allows alarm thresholds and appropriate safety functions to be activated before the concentration reaches a hazardous level.
Typical applications include boiler rooms, industrial facilities, gas installations, energy facilities, storage areas and other locations where flammable gases or vapours may be released.
Toxic Gas Detection and Oxygen Monitoring
EVIKON provides solutions for continuous monitoring of various toxic gases. Depending on the application, the system can monitor carbon monoxide (CO), ammonia (NH₃), hydrogen sulphide (H₂S), nitrogen dioxide (NO₂) and other gases that may become hazardous at certain concentrations.
A separate area of application is oxygen (O₂) monitoring. In enclosed and technical areas, the release of certain gases can displace oxygen and reduce its concentration to hazardous levels. In other processes, increased oxygen concentrations may also need to be monitored.
Continuous measurement enables timely warning and activation of appropriate safety functions.
CO₂ Detection and Indoor Air Quality Monitoring
Increased carbon dioxide (CO₂) concentrations can result from industrial processes, storage of certain products or high occupancy levels in enclosed spaces.
EVIKON CO₂ detectors and transmitters provide continuous concentration measurement and can be used for safety monitoring or as part of ventilation and indoor air quality control systems.
Refrigerant Gas Detection
An important part of the EVIKON portfolio is refrigerant gas detection, designed for early identification of potential leaks from refrigeration and air-conditioning systems.
The appropriate sensing technology is selected according to the type of refrigerant, required measurement range and operating conditions.
Typical applications include plant rooms, refrigeration facilities, cold stores, supermarkets, industrial facilities, heat pumps and other systems using refrigerants.
Early leak detection can provide several benefits, including personnel protection, system monitoring, prevention of significant refrigerant losses and automatic control of ventilation and other safety functions.
Gas Detection in Ex Hazardous Areas
Special requirements apply to areas where the presence of flammable gases, vapours or other substances may create a potentially explosive atmosphere.
In such areas, selecting the correct gas detector alone is not sufficient. The design must also consider the Ex zone classification, type of potentially explosive atmosphere, appropriate Ex/ATEX equipment, installation method and other application-specific requirements.
Correct system design and installation are particularly important because the gas detection system forms part of the overall concept for preventing and mitigating risks associated with explosive atmospheres.
From Detector to Complete System
Selecting the appropriate gas detection system begins with identifying the target gas, expected concentrations, measurement range, environmental conditions and potential leak sources.
The number and positioning of detectors are equally important. Detector placement depends on the physical properties of the gas, room configuration, ventilation, potential leak sources and other factors affecting gas dispersion.
The required system response must then be defined, including alarm thresholds, visual and audible signalling, ventilation control, gas supply shut-off, alarm transmission to the BMS or other safety functions.
Only by coordinating all these elements can a functional gas detection system be created that is properly adapted to the actual risks of the specific facility.
