Introduction

The equipment intended for installation and operations in the environment with the risk of gas and dust explosion, usually in underground coal mines are presented here. The main features of these products are the ability to work safely in the environment where there is a risk of methane explosion, their robustness and working reliability. All products have the certificate from the authorized test laboratory Nr. 210 in Ostrava Radvanice according to the European Directive Nr. 94/9/EC-ATEX.

We are able to adapt the current products or to develop completely new equipments according to your requirements. We have our own construction department equipped with special measuring technology (EMC etc.), whose staff are able to build electric and electronic equipment for the environments where there is a risk of dust or gas explosion in the field of heavy-current or light-current switching technology, long-distance communication, detection and analysis of gases, detectors and special devices.

Measuring
Mine atmospheric monitoring system	detectors intended for underground mine spaces and tunnels.
Level measuring	detectors for level measuring, incl. evaluating units in the intrinsically-safe design or in a fast closure.
Systems for seismic telemetry	serves for measuring of shock bumps in underground mine spaces and tunnels.
Communication, voice, picture and data transmission
Telephone communication system	is intended for communication of staff in underground mine spaces and tunnels with the surface. The system allows a voice call and controlling of various devices.
Mine telemonitoring system	is a modular system for two-way transfer of data, visulization and control between the mine and the surface.
Wireless communication of mine workplaces	is a system for communication in underground mine spaces and tunnels.
Voice communication system	is a system for communication in underground mine spaces and tunnels.
Camera system	is intended for underground mine spaces and tunnels.
High-frequency indication from the cage	the system for the communication from the cage.
Mine mercaptan indication	serves for calling of all workers from places in danger in underground mine spaces and tunnels.
Automation, converters, actuating units
Automation, measuring and controlling elements	serve for the measuring of physical properties in machines and equipments in underground mine spaces and tunnels.
Switching, controlling, connecting and indication technology
Indication, switching and connecting devices	for various types of button and connection boxes in fast closures or for intrinsically-safe devices.
Optics
Data Optical Cabinet	is used for converting SHDSL line data signals of RS485IS series line to the Ethernet signal for distance transmission by an optical cable.
Data Optical Converter	is used for converting a distance signal to the Ethernet signal for distance transmission by an optical cable.
POK-01 K	the pre-connected optical cable POK-01 is used for implementing detachable optical routes or connecting data optical cabinets to an optical route.
POK-01 S	the pre-connected optical cable POK-01 connecting cabinet is used for interconnecting individual sections of optical routes made of optical cables with pre-installed connectors.
Special measuring, monitoring and automaton systems
RK1	serves as a switchboard for reactive power compensation.
KOR-01	is used to perform corrosion tests of metallic materials.
Identification
DIK-01	DIK-01 mine identification card for identification of mine workers
ISI	Information system for identification of persons in the mine.
