Engineered protection for critical equipment in high-risk industrial zones
SomNandi Industries manufactures blast resistant enclosures built to keep control panels, instrumentation, and switchgear operational when a shockwave hits. Each unit is engineered around the equipment it houses and the exact overpressure it needs to withstand — not a generic rating pulled off a shelf.

Overview
Standard equipment housings are built for dust, weather, and daily wear — not for blast loading. In an oil & gas refinery, a chemical plant, or any facility running volatile processes near sensitive instrumentation, that gap becomes a real operational risk. A blast resistant enclosure from SomNandi Industries closes it, absorbing and redirecting blast pressure so the equipment inside stays functional and your process doesn't go dark when it matters most.

Blast Response Categories
Low Response Minimal deformation under high threat levels. Suited to extreme equipment sensitivity or high occupancy risk nearby.
Medium Response Balances protection and cost for moderate-risk zones. The most common configuration across process industries.
High Response Allowable deformation under lower threat levels. Fits less critical installations where budget efficiency matters more.
Acoustic Baffles Ceiling — Custom Configurations
For projects requiring non-standard layouts, mixed orientations, or baffles integrated into an architectural ceiling design, SomNandi Industries offers fully custom acoustic baffles ceiling configurations. Panel dimensions, suspension depths, orientations, and finish combinations can all be specified to meet both acoustic and design requirements within the same installation.
Applications Include:
- Architect-specified ceiling treatments
- Mixed horizontal and vertical baffle layouts
- Feature ceiling installations in public and commercial buildings
- Acoustic treatment integrated with lighting or HVAC design

FAQs - Blast Resistant Enclosures | SomNandi Industries
An enclosure protects specific equipment — panels, instruments, control systems. A building is a full occupiable structure for people and multiple equipment sets. Enclosures are smaller, faster to deploy, and priced for equipment-level protection.
Yes. Sizing runs from compact single-instrument housings up to multi-panel equipment rooms, depending on what needs protecting.
Through a hazard assessment covering overpressure, impulse duration, and distance from the likely blast source. The rating is set from that data, not a fixed catalog spec.
Yes. Class I Division 1 and Division 2 configurations are available based on your site's classification.
Routine inspection of seals, hinges, and access panels, plus periodic checks on positive pressure and gas detection systems if fitted. Full documentation ships with every unit.
Generally yes. Enclosures are designed around the equipment's footprint and connection requirements, so most existing panels and instruments can be housed without modification.
Timeline depends on configuration and blast rating. In-house manufacturing means no third-party fabrication delays.
Yes. Corrosion-resistant coating options are available for coastal sites or chemically aggressive atmospheres.
It comes down to acceptable deformation under blast loading. Low response allows the least deformation and suits the highest threat levels. High response allows more deformation and fits lower-risk, budget-conscious installations. Medium response covers most process industry cases in between.
