Safety at the Heart of the Global Process Industry
Solutions for Hazardous Areas (ATEX and IECEx)
ATEX and IECEx solutions are used wherever potentially explosive atmospheres may occur due to the presence of gases, vapours, or combustible dusts.
(Petro)chemical Industry and Power Plants
In chemical and petrochemical plants in particular, individual sample conditioning components or even complete analyser systems are often operated in hazardous areas. Most of these applications are related to process control, process optimization and process safety.
The use of explosion-proof solutions is also becoming increasingly common in power plants located in industrial parks, as well as in facilities for the incineration of industrial residues and waste. Due to the corrosive and potentially explosive substances encountered in the chemical and petrochemical industries, ATEX and IECEx components and systems are often required to meet particularly demanding operating conditions
PSG Process Probe for Hazardous Areas up to 180°C
One of the key advantages of the PSG Process Probe is that, thanks to its self-limiting heating cartridges (90°C, 150°C and 180°C), no additional controller or temperature limiting unit is required. In addition, the dissipative GRP protective enclosure provides a high degree of protection of up to IP65.
Even in applications with extremely demanding requirements for a stable extraction temperature of 180°C due to acid dew points, the self-limiting heating system ensures the required temperature is maintained, even at ambient temperatures as low as -40°C. The probe is certified for use in hazardous areas according to Zone II 2G Ex d IIC T3.
Special Filter Design for Low Maintenance
The specially designed filter surface ensures exceptionally long service life, both in applications with high dust loads and in those with very low dust concentrations – conditions commonly encountered in the process industry.
This feature enables operators of hazardous-area installations to minimize maintenance requirements and significantly reduce service times in their ATEX systems.
Cut-to-Length and Fully Certified: PSG Process ATEX
Even heated sample lines, which may appear to be simple components, must meet a wide range of requirements for use in hazardous areas. These include requirements relating to installation, routing, power supply and the electrostatic properties of the lines.
With the cut-to-length PSG Process ATEX heated sample lines, operating temperatures of up to 180°C can be achieved. Thanks to the convenient cut-to-length technology, the lines can be easily adapted to the exact length required for each installation.
Conductive Outer Jacket Material
This feature reduces installation effort, optimizes the use of resources and also saves energy. Thanks to highly efficient insulation technology and a maximum power output of 60 W/m, the heating tape enables energy savings of more than 50% compared with conventional solutions.
The patented fully dissipative (antistatic) outer jacket ensures that not only the heating tape itself, but the entire assembly is fully certified for use in hazardous areas.
PSG Process Cooler for ATEX Zones 1 and 2
Sample gas coolers in analyser systems are often installed in non-hazardous areas. However, for critical measurements, inerting applications or the analysis of flammable gases, process coolers designed for use in ATEX Zones 1 and 2 are increasingly required.
Integrated SIL Temperature Measurement
The new MAK Process combines all the key requirements of the process industry in a single device. High flow rates for reduced T90 response times, integrated SIL temperature measurement, welded gas paths and a stainless-steel heat exchanger ensure maximum safety and reliable operation of the sample gas cooler.
ATEX Compressor Cooler
For applications in hazardous areas, PSG Process Coolers are approved for use up to ATEX Zone 1 and provide efficient cooling for one to four sample gas paths.
Cooling is provided by a compressor-based system, ensuring stable and low outlet dew points even at high ambient temperatures.
