Gas Analyser Panels
Process gas analysers chromatographs, moisture analysers, H2S monitors, dew point analysers are essential for safety and process control in Oil & Gas and Petrochemical plants. Deploying them in classified hazardous areas requires a purpose-built, Ex p certified analyser shelter or enclosure that integrates the sample conditioning system, analyser power supply, purge and pressurisation control, calibration gas connections, and environmental conditioning into a single, field-ready assembly. Team Switchgear and Control LLC designs and builds custom gas analyser panel enclosures and shelters in Dubai for UAE and GCC Oil & Gas projects.

Analyser Enclosure Options
• Single-analyser Ex p enclosure compact format for individual field-mounted analysers
• Multi-analyser shelter climate-controlled, GRP or steel, housing 2–8 analysers with shared sample conditioning
• Analyser house (walk-in) full-size technical shelter with HVAC, lighting, and utilities for large analyser systems
• Fast loop sample handling systems integrated into the enclosure with heated sample lines, fast loop pumps, and vent panels
• Calibration gas manifold systems automatic and manual calibration gas injection, switchable multi-point
What We Integrate
• Sample inlet/outlet manifolds with certified Ex d valves and pressure regulators
• Heated sample lines with Ex i temperature controllers
• Sample pump (Ex d or Ex p rated) for fast loop circulation
• BARTEC Ex p purge controller Type X, Y, or Z purge per application
• Analyser power supplies with Ex i barriers for 4-20mA and digital signal isolation
• HVAC or thermostatically controlled ventilation maintaining analyser operating temperature in ambient to 60°C UAE climate
• Internal lighting (Ex e or Ex p rated) and maintenance socket
• Calibration gas ports with certified check valves and pressure gauges
Can you supply LCS with both local and remote control capability?
Yes. We regularly supply LCS units with an integral HOA (Hand/Off/Auto) selector switch that enables the operator to select between local manual control at the station and remote control from a DCS, PLC, or MCR. The HOA switch in the ‘Auto’ position passes control to the remote system; in ‘Hand’ position, the local pushbuttons are active. Feedback signals (running, tripped, valve position) can be provided via Ex i (intrinsic safety) 4-20mA loops or digital I/O.
What is your lead time for custom explosion proof LCS?
Standard 2–3 element LCS units (start/stop, E-stop) in GRP or aluminium Ex d enclosures are typically available within 3–6 weeks from approved drawings. More complex multi-function stations with custom operators, indicators, and instrument interfaces require 6–10 weeks. Rush delivery can be discussed depending on component availability.
