How do you design an analyzer shelter for process analyzer installations?

Analyzer shelter design considerations: environmental control (HVAC for temperature 15-35 degrees C, humidity <85%, pressurization for hazardous area classification reduction), utilities (instrument air, power - UPS for critical analyzers, sample conditioning utilities), sample transport (heated lines, proper routing, minimum dead volume), safety (H2S/LEL detection, ventilation, emergency stops), layout (accessibility for maintenance, logical arrangement), and classification (Division 2/Zone 2 typical with purge). Structural: wind/seismic loads, corrosion resistance. Documentation: P&IDs, location plans, classification drawings. Consider modular/prefabricated shelters for standardization and faster installation. Size for current needs plus expansion.
