What is it?
Control Rooms
Control rooms are the nerve centres of critical industrial infrastructure — a failure of the control room environment means a failure of the process it monitors. Temperatures that exceed equipment operating limits, vibration from adjacent machinery, electromagnetic interference from HV switchgear, or a blast event from adjacent process plant can all compromise control room integrity. Poojary Prefab's prefab control rooms are engineered specifically to prevent these failure modes — each designed around the equipment it houses, the process environment it faces, and the regulatory standard it must meet.
Our control rooms are factory-built, precision-engineered structures that arrive on site as complete, tested units. Structural steel framing, insulated sandwich panel cladding, internal partition systems, raised access flooring, precision HVAC, cable entry management systems, and anti-static finishes are all factory-installed and commissioned before dispatch. This factory-assembly approach eliminates the quality variability that plagues field-built control rooms and guarantees environmental performance from day one of operation.
We serve the full spectrum of critical infrastructure operators: power generation plants (thermal, hydro, solar, nuclear-adjacent), high voltage substations, oil and gas upstream and downstream facilities, LNG terminals, refinery process units, petrochemical plants, and water treatment facilities. Our control rooms are designed in compliance with IS 50244, IEC 61340 (electrostatic discharge), IEC 60529 (IP rating), and blast loading standards where specified. Documentation is provided for CEIG, PESO, OISD, and international regulatory submissions.
Configurations
Which Type Do You Need?
Every site has different requirements. Here's how our range breaks down.
Substation Control Room
Insulated, climate-controlled buildings for HV/EHV substation SCADA and relay rooms. CEIG-compliant construction, anti-static flooring, segregated cable entry, and EMC shielding. Designed for IS 50244 and IEC 61439 compliance.
DCS / SCADA Operations Room
Positive-pressure climate-controlled rooms for DCS consoles, SCADA workstations, and operator interfaces. Precision air conditioning, raised access flooring, uninterrupted power provisions, and ergonomic operator console layout provisions.
Blast-Resistant Control Room
Structural panels designed to specified blast overpressure — typically 0.5–3.0 psi for process plant applications. Mass-plate clad construction, blast-rated door and window assemblies, and full compliance with ASCE 7 blast design provisions. For refineries, LNG terminals, and explosive risk zones.
Remote / Unmanned Substation Building
Compact, secure buildings for unmanned remote substations and telecom facilities — vandal-resistant cladding, access control provisions, environmental monitoring, and communication infrastructure mounting provisions. Designed for minimal maintenance in remote locations.
Key Benefits
Stronger by Design. Smarter by Choice.
Blast-Resistant to International Standards
Our blast-resistant control rooms are designed to ASCE 7 blast loading provisions and ISO 17776 (offshore risk) guidelines. Mass-plate construction, blast-rated door and window assemblies, and pressure-venting provisions ensure personnel safety and equipment continuity in the event of an adjacent process blast event.
Precision HVAC for Equipment Reliability
DCS and SCADA equipment operates reliably only within defined temperature and humidity bands — typically 20–25°C, 40–60% RH. Our N+1 precision HVAC maintains these conditions under all external conditions, with positive pressure preventing dust ingress and HEPA filtration options for chemically corrosive atmospheres.
Factory-Tested Before Dispatch
Every control room undergoes factory acceptance testing before dispatch — HVAC performance, cable entry integrity, raised floor load tests, and electrical continuity. On-site commissioning is reduced to service connections and final instrument hook-up. No remediation of site-built quality failures.
Full Regulatory Documentation Package
IS 50244, IEC 61340, IEC 60529 compliance certificates, blast calculation reports, structural design certificates, and HVAC performance documentation. Ready for CEIG, PESO, OISD, and international regulatory authority submissions.
