Custom-Engineered Industrial EnclosuresBuilt for the Harshest Operating Environments
Hazardous area classification · Acoustic isolation · High-temperature design · Weather-rated cladding · ATEX-compatible options
What is it?
Industrial Enclosures
Industrial plants, power generation facilities, oil and gas installations, and chemical processing sites routinely require dedicated enclosures that go far beyond weather protection. Equipment must be isolated from vibration, protected from explosive atmospheres, shielded from corrosive environments, or contained within acoustic boundaries — all while remaining accessible for maintenance and fully compliant with statutory safety requirements. Poojary Prefab engineers these enclosures as purpose-designed structures, not modified general-purpose cabins.
Every industrial enclosure we fabricate is designed from scratch around the equipment it houses, the environment it operates in, and the regulatory classification it must meet. Generator set enclosures are designed to CPCB II emission norms and acoustic standards; electrical room enclosures are designed to IP54 minimum protection with fire-rated construction; pump house enclosures for oil and gas are designed to PESO hazardous area Zone 1 or Zone 2 classifications as required. We engineer the entire envelope — structure, cladding, HVAC provisions, cable and pipe entry management, ventilation, and fire suppression provisions.
We serve clients across the power sector (thermal, solar, hydro, wind), oil and gas upstream and downstream, petrochemical, water treatment, pharmaceutical manufacturing, and heavy engineering industries. Our enclosures are fabricated at our Wagholi, Pune facility and dispatched as complete factory-assembled units, minimising on-site work and ensuring quality consistency across multi-site deployments. Delivery in 21–45 days from design sign-off.
Configurations
Which Type Do You Need?
Every site has different requirements. Here's how our range breaks down.
Generator Room Enclosure
Acoustic and weather-rated enclosures for diesel generator sets from 10 kVA to 3,000 kVA. CPCB II compliant acoustic attenuation, louvred ventilation, radiator exhaust provisions, fuel tank provisions, and cable entry management. Attenuation to 75 dB(A) at 1 metre as standard.
Electrical Room & Switchgear Housing
Fire-rated, climate-controlled enclosures for HV/LV switchgear, transformers, MCC panels, and battery rooms. FRL 60 or 120 min as specified, HVAC provisions, cable underfloor provisions, anti-static flooring, and forced ventilation with fire dampers.
Acoustic Enclosure
High-performance acoustic enclosures for compressors, turbines, blowers, and rotating equipment. Rockwool / mass-loaded vinyl lining, floating-floor provisions, anti-vibration mounts, and acoustic door sets. Custom attenuation targets up to 50 dB(A).
Pump House / Hazardous Area Enclosure
PESO Zone 1 and Zone 2 classified enclosures for pump houses, metering stations, and chemical dosing rooms. Explosion-vent panels, flameproof electrical fittings, ventilation designed to 12 air changes per hour, and corrosion-resistant cladding for aggressive chemical environments.
Key Benefits
Stronger by Design. Smarter by Choice.
Hazardous Area Classification Ready
PESO Zone 1 and Zone 2 classified enclosures with explosion-vent panels, intrinsically safe wiring provisions, and ATEX-compatible fitting specifications. Documentation ready for PESO, CCOE, and OISD regulatory submissions.
Acoustic Performance to Specification
Generator and compressor enclosures designed to client-specified noise targets — typically 75 dB(A) at 1m for CPCB compliance or custom attenuation for residential boundary requirements. Test reports and insertion loss calculations provided.
Factory Assembly — Minimal Site Work
Enclosures arrive factory-assembled and tested. On-site work is limited to levelling, anchor bolt installation, and service connections. This eliminates quality variability, reduces commissioning time, and allows identical replication across multi-site plants.
Full Compliance Documentation
Complete documentation package: structural calculations, acoustic test reports, fire resistance certificates, IP rating test certificates, and PESO/ATEX compliance declarations. Ready for statutory approvals, insurance underwriting, and third-party inspection.
