We work with several renowned manufacturers of valves and pressure reducers. Over time, the design of these regulators has continuously evolved to ensure enhanced protection and easier operation of measuring instruments.

This development has led to the integration of measuring instruments directly into the valves, known as VIPR (Valve with Integrated Pressure Regulator). Initially, mechanical versions were used, which were later replaced by mechatronic or electronic instruments.

The main function of the measuring instruments in such pressure reducers is to measure the pressure both in the gas container and in the supply line. Modern electronic versions offer additional features, such as displaying the remaining operating time, gas throughput, and fill level, they trigger alarms at low gas content, and enable wireless communication.

Using natural gas as a fuel for vehicles offers significant savings in fuel costs, with up to 60% savings compared to conventional fuels. Furthermore, natural gas is among the most environmentally friendly energy sources. Compared to gasoline or diesel, it causes significantly fewer emissions of unburned hydrocarbons, which are classified as harmful and potentially carcinogenic, and reduces CO2 emissions by about 20%.

This not only contributes to environmental protection but also allows vehicles powered by natural gas to gain access to zones that are closed to conventionally powered vehicles due to emission restrictions. To monitor the current level of compressed natural gas (CNG) or liquefied natural gas (LNG) in the vehicle’s tank, special measuring instruments are used. These instruments are crucial for the safety and efficiency of the operation, providing accurate data on the available fuel quantity and thus enabling optimal use of the vehicle.

Respiratory protection devices, also known as Self-Contained Breathing Apparatus (SCBA), Compressed Air Breathing Apparatus (CABA), or simply breathing apparatus (BA), are essential equipment for individuals required to work in potentially life-threatening or harmful environments. This includes emergency services such as firefighters and rescue services, who operate in smoke-filled, toxic, or oxygen-deficient areas.

These devices are equipped with special display instruments, which are either attached directly to the valve of the breathing air cylinder or to a portable device. These displays are crucial as they provide users with an accurate reading of the remaining oxygen content in their tanks. This information is critical for knowing the remaining operational duration and to ensure there is sufficient time to either complete the task or retreat to a safe location before the oxygen supply runs out. The development and integration of advanced sensor technology into these display instruments now allows users to receive even more precise data about the oxygen supply and to activate warning signals at low oxygen levels, significantly improving safety and efficiency during operations.

A gas cylinder bundle is an arrangement of multiple gas cylinders typically used to distribute gases through a piping system. These cylinders are divided into a primary and secondary group via a valve block to ensure efficient use and continuous gas flow. Initially, gas is drawn from the primary bundle, with even distribution ensured by their parallel arrangement at a common outlet.

Once the gas volume in the primary cylinders reaches a critical minimum, a pressure transmitter enables the switch to the secondary bundle. This system allows for the exchange of the primary bundle without interrupting the gas supply. Valve blocks are used to direct the gas from a central point to multiple withdrawal points. Particularly in medical facilities, such as hospitals, these gas distribution systems are utilized for the provision of various gases, including nitrous oxide, Entonox, and oxygen. These systems are essential for maintaining a reliable and safe gas supply for different applications, including the supply to emergency facilities and operating rooms.

The fire protection industry plays a crucial role across a wide spectrum of areas – from industrial facilities to commercial establishments, residential buildings, and building services. There are fundamentally two strategies for fire protection: One aims to reduce the oxygen content in the ambient air to a level that prevents independent fire propagation. The other method involves the use of chemical agents that react with the heat of a fire and initiate a chemical chain reaction that effectively interrupts combustion.

Gas extinguishing systems, including CO2, FM200, Novec, Inergen, and Argonite, play a pivotal role in protecting assets and human lives in various environments such as residential buildings, data centers, hospitals, hotels, parking garages, restaurants, universities, factories, and processing plants.

Manometers in these systems take on the important task of monitoring the pressure within the gas cylinders and triggering alarms when deviations from the set points occur. For use in stationary installations, certification according to VdS or LPCB is required. Mobile systems, on the other hand, are not subject to this certification requirement.

Effective monitoring and maintenance of these systems are crucial to ensure their performance and reliability. Modern fire protection systems often integrate advanced sensor technologies and automated monitoring solutions to ensure a quick response in the event of a fire and continuous efficiency in operation. This achieves optimal protection of buildings and critical infrastructures against fire and smoke, while simultaneously maximizing the safety of the people within.
