For more than 30 years, J.T.O. System, s.r.o. is engaged in the development, manufacture and sale of equipment for gas detection. Customers can choose from both, portable devices designed for service or inspection workers in the gas industry and the systems and equipment belonging to the category of fixed gas detectors mounted permanently in supervised premises such as boiler rooms, garages, technological businesses, etc.

In our work, we strive for a high quality standard, as evidenced by the established and certified quality management system of production according to ISO 9001.

To support our customers, we provide also additional technical information focused on the selection, installation and operation of our gas detectors. If you need to consult a special deal, do not hesitate to contact us. We look forward to our mutual cooperation.

Fixed detectors

Fixed gas detectors are represented by multiple series of devices.

Flammable gases such as natural gas, LPG, solvent vapors and other flammable substances can be detected in a standard environment using a two-stage GC20P detector or a three-stage GI30W detector. Detector GC20P could be ordered also for 230 V / 50 Hz power supply as GC20P-230V or as GC20P-FGD which also allows the connection of an external detector and includes a siren and a voltage source for the emergency valve. GSC4 is a sensor for flammable gases with 4-20 mA current loop output.

In places with Zone 2 explosive atmosphere you can use GR31 detectors.

A three-stage GIC40 detector, two-stage GICO20-230V for 230 V / 50 Hz power supply, GICO20P-FGD, which also allows the connection of an external detector and includes a siren and a voltage source for the emergency valve, and 4-20 mA current loop sensor GSU2 are intended for detection of carbon monoxide (CO) in the atmosphere.

A carbon dioxide (CO₂) could be detected by two-stage detector GIR80 or sensor GSR8 with 4-20 mA current loop output and 0-10 V voltage output.

A special category is represented by a refrigerant detector GC20R that responds to the filling of the cooling devices based on R134A and GC20RF-230V for 230V / 50 Hz power supply. Another special category is the GSK2 oxygen concentration sensor equipped with a 4–20 mA current loop output.

Portable devices

For service and inspection workers, we produce general-purpose detector GD550, a device that allows using interchangeable probes to measure and detect more variables, so that in one practical plastic case, the customer can create a setup according to their own needs. The basic options include: detection of flammable gases and carbon monoxide in the air, measuring pressure and temperature. GD550 can be also suplemented with a sensor for measuring low air pressure (4 Pa test) or with a simple flue gas analyzer.

For boiler room operators or when occasional checks are required, we can offer a simple single-purpose GOFL instrument for detecting combustible gases or a GOCO instrument for detecting carbon monoxide. We also offer single-purpose detectors — the GORF for locating refrigerant leaks and the GOOX for monitoring carbon dioxide (CO₂) concentration in indoor environments such as offices or classrooms.

Auxiliary components

Fixed detectors can be used separately as input devices connected to the control system. If the detection system is to function independently, the detectors are usually suplemented with the power supply NZ22, NZ44, NZ425, alarm control panel FZ28 or even sirens and beacons. The previously manufactured NZ34 power supplies have been replaced by NZ22 or NZ44 models.

For more complex systems, we also offer SF14 flood sensors and ST24 temperature sensors, which can be easily connected to our systems.

A new type of detector with a higher degree of protection. It replaces the older detectors GI31 designed for the ZONE 2 environment.

GIC40N detectors are designed to detect carbon monoxide in indoor spaces such as parking houses, boiler rooms, technological businesses etc.

GSU2N is a simple carbon monoxide concentration sensor.
