Providing high quality solutions is one of our main goals: cabinets and/or cabinets can be made of a wide range of materials, including galvanized steel, stainless steel, glass reinforced plastic, concrete, designed according to NFPA 496, IEC 61285, GOST, ECAS or any other international standard and are always complete with the relevant ATEX and DNV certificates.

Safety and reliability are considerations of the utmost importance in the field of process analysis, in fact, our cabinets guarantee a safe environment from external factors such as atmospheric agents, dust and other contaminants, guaranteeing the correct functioning of the instrumentation inside.

We supply all our systems fully equipped with gas/liquid analyzers and samplers, complete with auxiliary equipment such as sample conditioning systems, power and ventilation systems, components such as pre-installed piping and wiring to connect the application to the process.

HVAC | Heating, Ventilation and Air Conditioning

HVAC (Heating, Ventilation, and Air Conditioning) or HAC (Heating and Cooling) play a fundamental role in analysis cabins, contributing significantly to the precision and reliability of the results obtained. These systems guarantee a controlled and optimal environment inside the cabin, maintaining constant temperature, humidity and ventilation conditions necessary for analysis operations.

Our HVAC/HAC are designed taking into account project requirements and system specifications, guaranteeing stable environmental conditions to ensure the reproducibility and reliability of continuous analysis. Thanks to accurate control of temperature and humidity, our systems help preserve the integrity of the samples and minimize variations that could influence the analysis results.

Furthermore, proper ventilation provided by the HVAC or HAC ensures adequate air circulation within the cabin, minimizing the presence of contaminants and ensuring a safe and comfortable working environment for testing personnel.

SME | Continuous Emission Monitoring Systems

Continuous Emission Monitoring Systems (EMS) play a crucial role in monitoring and managing the environmental impact of industrial activities.

Our offering includes SMEs designed for use in both hazardous and safe areas. Our added value consists in identifying appropriate instruments and analyzers for the specific application, equipped with analytical measurement technologies compliant with the reference standards, such as EN 14181, among others.

Value Proposition

Accuracy and Reliability: Our EMS provide accurate and reliable measurements of gaseous and particular emissions from industrial plants, allowing companies to accurately assess their environmental impact and identify potential areas for improvement.

Regulatory Compliance: Our systems are designed to meet rigorous environmental regulatory standards and allow companies to continuously monitor their emissions to ensure compliance with local, national and international regulations.

Process Optimization: Using the data collected by our systems, companies can analyze the performance of their plants and optimize production processes to maximize energy efficiency, reduce operating costs and minimize overall environmental impact.

SWAS | Steam and Water Analysis Systems

Our SWAS systems are designed to provide accurate, real-time analysis of the chemical/physical characteristics of water, allowing operators to closely monitor water quality and intervene promptly in case of any variations or anomalies. Our solutions are complete with everything necessary for sample collection, conditioning and analysis, and are made according to the international reference standards ASME PTC 19.11, VGB/DGRL and ASTM D5540.

Sampling systems are mainly used in combination with water analysis equipment for chemical parameters such as conductivity, pH, dissolved oxygen, silica, sodium etc.

Our solutions can be customized to different specifications (low or high pressure, low or high temperature, low or high sample flow) and are made of high-quality materials to ensure safe operation and representative samples at the desired conditions. The water and steam analysis systems are characterized by a modular and flexible design, which allows for rapid and customized installation to adapt to the specific needs of each industrial plant.

Sampling Systems

With extensive industry experience spanning over 30 years, we can provide comprehensive system design and manufacturing services for sampling (SP), pre-treatment (PSTC) and sample processing (STC). Our goal is to ensure that each solution is perfectly tailored to the specific needs of the process, ensuring that analyzers receive representative samples to obtain accurate and reliable measurements.

Our solutions are designed for use in outdoor industrial environments, compliant with Safe Zone and ATEX safety standards.

The sample processing system is an indispensable part of the analysis loop and must be designed with high quality standards to ensure the correct representativeness of the sample before it reaches the analyzer.

Each system can have different configurations dictated by the sample conditions at the sampling point. Based on these conditions, the system can be simple, for example limited to a pressure reduction, or become more complex if filtering is required for particularly contaminated samples, removal of aggressive substances or condensation harmful to the analyzers. It is important to underline that incorrect design of the sample processing system represents one of the main causes of analyzer failures and high maintenance costs.

The set of equipment necessary for this purpose is called the analysis system and is composed of:

Removable and fixed Sample Collection Probe (SPC):

Sample Pre-Treatment System (SPTC):

Auxiliary pump;
Pressure regulator;
Vaporization pressure regulator;
Cooling or heating system;
Pressure indicator;
Temperature indicator.

Sample Treatment System (STC):

Reduction or increase in blood pressure;
Filtration from particles and/or condensation;
Heating or Cooling the temperature;
Fast-loop flow regulation (kept to a minimum to avoid long sample delay);
Automatic selection of process streams and calibration;
Flow regulation to the analyzer;
Safety Valve (spring return and/or safety valves);
Sample taken for laboratory and/or integrated sampling system with canister.

Fire & Gas Systems

Our complete solutions for fire & gas detection systems are designed for both on-shore and off-shore applications, using advanced technologies of specific control panels or PLCs.

The detection of gas leaks, smoke and fires today represents an active protection measure against serious accidental events that could cause partial or total damage to industrial plants or sites. This type of detection is also fundamental for the health and safety of people and the protection of the environment. In fact, a carefully designed fire & gas detection system becomes an important ally in the management of industrial risks.

Our fire & gas systems are designed to include one or more control panels connected to field detectors, signaling devices and actuators.
The intervention function is related to other higher systems such as ESD (Emergency Shutdown System) or DCS (Distributed Control System) and is used to transfer confirmation that certain dangerous conditions have been detected. The ESD or DCS normally acquires this intervention and processes the shutdown of the process equipment involved in the hazard, the shutdown of ventilation, the deactivation of rotating equipment or generators, etc.
