High-performance gas conditioning for combustion gas analysers

Founded in 1994, Mega System Srl designs and manufactures systems for environmental control and pollution monitoring. Thanks to its many years of experience and its team of qualified professionals, Mega System offers ‘Made in Italy’ tools of high quality and precision.  All stages of the production process take place within the company, from hardware design to after-sales assistance, allowing the company to meet every customer need, offering optimal all-round assistance.

Since July 2017 Mega System is a calibration laboratory LAT accredited by ACCREDIA in conformity with ISO 17025 for the execution of calibrations for volume, mass flow, pressure and temperature.

Building on their expertise and commitment to innovation, the company are proud to introduce ARTIK AIR, a gas conditioning system designed for emission sampling and optimised for use with combustion gas analysers.

The system offers two key strengths. First, it features an innovative two-stage design that combines pre-condensation using compressor cooling with further cooling via Peltier cells, ensuring efficient temperature control. Second, it incorporates a borosilicate heat exchanger structure that minimises the contact time between the sample gas and the condensate. This design significantly reduces the solubilisation of volatile components, such as SO₂, which would otherwise be lost in the liquid phase.

Artik Air includes a membrane pump resistant to corrosive gas attack, with high pressure and flow rates exceeding what is normally required by gas analysers. The pump is internally regulated by a temperature sensor that activates the suction once the user-set point is reached and turns it off in case of exceeding a safety temperature.

The gas outlet temperature from the system can be easily checked with an external thermocouple and complies with the UNI EN 15058 standard (< 4°C), without requiring the use of thermocouples installed inside the system, which cannot be properly verified by a calibrated thermometric chain.

The peristaltic pump installed in the system allows for the automatic and continuous removal of condensate, which can be collected, if necessary, for subsequent laboratory analysis via a pneumatic connection.

An external display shows the gas outlet temperature, which is monitored by the electronics and kept constant.

The ergonomic design, optimized for reduced dimensions and weight, facilitates easy handling of the system, despite the high cooling capacity that allows its use even under conditions of high temperature and humidity in the incoming gas.
