Reliable and Innovative Gas Safety Systems
Devices in this category HVAC

In this category, you will find products intended for gas detection in public utility buildings.


Stationary Gas Safety Systems have been widely used for many years in public utility and industrial facilities to protect people, property and the environment against gas hazards. The presence of hazardous gases in the surrounding atmosphere concerns not only trained personnel of highly specialized industrial plants, but also unprepared or particularly sensitive people, such as children, pregnant women and the elderly.

In our opinion, both of the above groups require equally high protection and attention as well as reliability on the part of persons responsible for the safe operation of technical systems. The solutions that we develop are reliable and innovative, and additionally have implemented functionalities that are unheard of in existing solutions.

Atest Gaz has been operating on the general construction market from the very beginning of its activity. We offer two product lines for gas detection, both in the area of ​​heating and ventilation: Alpa Gas XT and Teta Gas.



System Teta Gas System

Teta Gas system is a modern Gas Detection System that uses Digital Data Transfer – Teta BUS, which via a single pair of cables, allows for both supply and addressable communication with the gas detectors. It is intended to provide security of public utility, civil engineering and residential facilities (underground garages, boiler rooms or halls heated with radiators) and protect people staying at such facilities from dangerous gas hazards– CH4 or toxic CO/ NO2.

Teta Gas also provides protection against flammable gases from LPG installations in cars or H2 in battery charging rooms - (Teta EcoH - New!).

System Alpa Gas XT

The Alpa Gas XT system is designed to protect public utility facilities such as underground garages, halls heated with radiators and gas boiler rooms. It provides protection for people staying in them against highly poisonous gases, such as carbon monoxide or nitrogen oxide, and against flammable gases from LPG systems in cars or methane from heating systems. It allows for 3-stage detection.

The system communicates in the 4-20 mA standard.
