Gas detection systems

Where a gas detection system is a must?

Enclosed spaces pose a risk of accumulation of harmful gases. The gas detection system is the right solution when you need to secure production facilities, residential buildings and underground parking lots.

In production facilities

The technological process in some industries involves working with explosive or toxic gases. In such premises a gas detection system is built, which, when reaching a certain gas concentration, sends a signal to other emergency response systems: switches off the gas flow in the room, triggers emergency ventilation, switches off power supply and operational ventilation, turns on emergency lighting, light and sound alarms, starts a system for creating increased pressure in fire protection entrance halls, etc. In industrial and power generating premises, alarm systems are usually planned as early as at the design level.

In the underground parking lot

Do you know that in underground garages the risk of accumulation of dangerous and harmful gases is extremely high? The large number of cars in the closed space of the underground parking lot creates conditions for the accumulation in the atmosphere of carbon monoxide (CO) emissions, which is very dangerous for humans. This gas has no colour or odour, and its high concentration leads to hypoxia and death. Cars equipped with gas systems carry the risk of leakage of other hazardous gases (propane-butane or methane) and an increase in their concentration to explosive levels. This type of sites are secured with modern gas detection systems, which usually consist of a control panel and dedicated detectors for different types of gases.

At home

Household gas detectors take care of our safety at home. They monitor the concentration of hazardous gases and vapours of volatile organic solvents in domestic conditions and, when the maximum permissible levels are exceeded, trigger a sound and light alarm. Different household gas detectors are available depending on the controlled gas: for methane (CH4), for propane-butane (LPG), for carbon monoxide (CO), for air quality (volatile organic compounds).

Applying a comprehensive approach, ANDY’s specialists will offer the right solution for each task depending on the conditions of the site and the customer’s requirements.
