Brand: Servomex

Description

Overview

The Servomex SERVOPRO 4900 Multigas is a high-performance continuous emissions monitoring system (CEMS) analyzer designed for a wide range of multi-gas flue gas measurements. Delivering up to four simultaneous gas stream measurements from a compact, small-footprint chassis, the SERVOPRO 4900 Multigas combines Servomex’s leading-edge, non-depleting sensing technologies with a modern digital platform to give plant operators next-generation performance at a low cost of ownership.

Working closely with plant engineers in the region, Seven Star LLC proudly supplies the SERVOPRO 4900 Multigas to power generation, refining, and process facilities throughout the Sultanate of Oman and the wider GCC. Every analyzer is supplied with manufacturer documentation and the regional technical support that regulatory-grade emissions monitoring demands.

Measurement Principle

The Servomex SERVOPRO 4900 Multigas combines three sensitive, highly stable non-depleting technologies to deliver measurements plant operators can rely on for regulatory compliance: Paramagnetic oxygen sensing, Single Beam Dual Wavelength (SBDW) non-dispersive infrared (NDIR), and Gas Filter Correlation (GFx) NDIR. Because these sensing technologies do not deplete or consume reagents over their operating life, the analyzer maintains long calibration intervals and stable accuracy without the frequent sensor replacement that affects electrochemical or depleting-cell alternatives.

This combination of technologies allows the SERVOPRO 4900 Multigas to simultaneously measure criterion pollutants and greenhouse gases from a single sample stream, oxygen, carbon dioxide, and carbon monoxide at percent level, alongside sulfur dioxide, nitric oxide, methane, and nitrous oxide at ppm level, giving plant operators a comprehensive emissions picture from one integrated instrument rather than multiple single-gas analyzers.

Engineering Design of the Servomex SERVOPRO 4900 Multigas

The SERVOPRO 4900 Multigas measures 132.5 mm (5.2 in) high in its standard chassis, or 265.5 mm (10.5 in) with the extended chassis, by 481.6 mm (19 in) wide and 544.2 mm (21.4 in) deep, weighing approximately 14 kg (30.9 lb) for the base unit. This compact, rack-mountable footprint integrates effortlessly into existing CEMS cabinets and control shelters, reducing installation costs compared to bulkier multi-analyzer configurations. An external NOx converter can be added to analyze and speciate NOx into NO and NO2 for facilities requiring full nitrogen oxide reporting.

The analyzer communicates via analog and serial outputs alongside digital protocols including RS232/RS485 Modbus, PROFIBUS, and Ethernet (Modbus TCP/IP) for flexible integration into plant SCADA and emissions reporting systems. An icon-driven color touchscreen provides intuitive local configuration and diagnostics, while a USB serial port supports data logging and software upgrades. Auto-calibration functionality enables low-cost remote calibration, and exportable diagnostic values support preventative and predictive maintenance programs.

Industrial Applications

The Servomex SERVOPRO 4900 Multigas is specified across power generation, petrochemical, refining, waste incineration, iron and steel, pulp and paper, and cement manufacturing, wherever continuous emissions monitoring is a regulatory requirement. In Oman’s power generation and refining sector, the SERVOPRO 4900 Multigas’s MCERTS and QAL1 certification supports compliance reporting for criterion pollutants and greenhouse gas emissions from combustion and process sources.

With fast quotation turnaround and technical support, Seven Star LLC distributes the SERVOPRO 4900 Multigas to thermal power plants, petrochemical complexes, and industrial facilities across Muscat and the Sohar and Salalah economic zones. Its compact footprint and auto-calibration capability make it well suited for retrofit CEMS upgrades and new-build emissions monitoring systems throughout the GCC’s power and heavy industrial sectors.

Why Choose Seven Star LLC for Servomex Continuous Emissions Monitoring Systems

Specifying a CEMS analyzer correctly means confirming which certification standard (MCERTS, QAL1) your local regulator actually requires and designing a sample-conditioning system that matches your stack gas composition and moisture content — an analyzer that meets the letter of a datasheet but the wrong sampling design will fail commissioning audits. Seven Star LLC works with your environmental compliance team to confirm the correct SERVOPRO 4900 Multigas configuration and communication protocol for your plant’s reporting system before order confirmation, drawing on our trusted Servomex suppliership across Oman and the wider GCC. We also support power generation and refining facilities in Sohar and Salalah with sampling system design guidance and coordinate calibration gas procurement so CEMS installations stay audit-ready from commissioning onward.
