ABOUT SR ENVIRO ENGINEERING

Equipment engineered for the plant floor, not the catalogue.

We are one of India's established names in the design, engineering and manufacturing of air pollution control systems, dust collection systems, flue gas desulphurisation, and material handling equipment for industrial plants.

Every system we build — from a single knife gate valve to a complete wet ESP installation — is engineered around the actual process conditions of the plant it serves: dust load, gas temperature, moisture, and duty cycle, not a standard datasheet.

What we bring to a project

01
Process-first design

Equipment sized against your actual dust load and gas chemistry, not a generic spec sheet.

02
Single-source scope

Design, fabrication, and field spares under one roof — one point of accountability.

03
Boiler-side expertise

Boilers and boiler spares handled alongside the pollution control equipment they feed.

04
Retrofit-ready

Systems built to slot into existing plant layouts and ducting, not just greenfield sites.

PRODUCT RANGE

Systems and components, engineered to work together.

Air pollution control equipment, gas cleaning systems, and the material handling components that support them — designed and manufactured to fit your process line.

Air Pollution ControlGas CleaningMaterial HandlingValves & DampersBoiler & Spares

Pulse Jet Bag Filter

High-efficiency fabric filtration for fine particulate capture across dusty process streams.

Wet ESP

Wet electrostatic precipitators for sub-micron particulate and mist removal at high efficiency.

Wet Scrubbers

Gas absorption and particulate scrubbing systems for acid gas and dust-laden exhaust streams.

Flue Gas Desulphurisation

FGD systems engineered to bring SO₂ emissions within regulatory limits for boiler and kiln plants.

Cyclone Separator

Centrifugal pre-separation for coarse particulate, reducing load on downstream filtration.

Biomass Dryer

Moisture-reduction systems sized for consistent throughput on variable biomass feedstock.

Screw Conveyor

Bulk material conveying for ash, dust, and process by-products with abrasion-resistant construction.

Rotary Air Lock Valve

Continuous material discharge under pressure differential, sealed against air ingress.

Ash Conditioner

Wets and conditions dry ash for safe, dust-free handling and disposal, in any capacity required.

Centrifugal Blower

Process air and gas movement engineered against your system resistance curve.

Industrial Fan

Axial and centrifugal fans for ventilation, draft, and process gas handling duties.

Knife Gate & Slide Gate Valve

Isolation and flow-control valves for slurry, ash, and bulk powder lines.

Butterfly Damper

Gas flow control and isolation for ducting across pollution control and process lines.

Boiler & Boiler Spares

Boiler units and a full range of spares, supplied and supported alongside your emissions systems.

Dust Collection Systems

Complete capture-to-discharge dust systems, engineered around your specific process layout.

HOW WE WORK

From site data to commissioned system.

A project moves through four stages, with our engineering team involved at each one — not handed off after the drawing is signed.

STAGE 1

Site & process study

We assess dust load, gas volume, temperature, and existing layout before any sizing begins.

STAGE 2

Design & sizing

Equipment is engineered and drawn against your specific operating conditions, not a stock model.

STAGE 3

Fabrication

Built in-house under our own quality checks, with material traceability at every stage.

STAGE 4

Erection & commissioning

Our team supports installation and start-up on site, and stays on for spares and service after.

WHO WE BUILD FOR
