Unicon Engineers

What Unicon Engineers does

Unicon Engineers is an Indian industrial manufacturer and exporter headquartered in Coimbatore, Tamil Nadu, founded in 2008 as a partnership firm. The company designs, engineers, fabricates, supplies, erects, and commissions air pollution control equipment — primarily Electrostatic Precipitators (ESPs), bag filters, gas conditioning systems, and material handling equipment — for thermal power plants, steel plants, cement plants, sugar factories, pulp and paper mills, and chemical facilities. Core technology centers on particulate matter removal with claimed efficiency up to 99.99% and outlet emissions below 10 mg/Nm3, supported by Computational Fluid Dynamics (CFD)-based gas distribution analysis and a licensed patented Ammonia Flue Gas Conditioning (AFGC) technology from the Heavy Water Board (Department of Atomic Energy) that reduces SPM from 600-700 mg/Nm3 to 20-70 mg/Nm3 in coal-fired boiler ESPs.

The company operates a vertically integrated hardware-plus-services business model, selling complete ESP systems (Rs 10-50 lakh per piece), component spares (Rs 149-Rs 15,000 per piece), and aftermarket services including shutdown maintenance, retrofitting, and upgradation contracts (Rs 5-25 lakh each). Go-to-market is enterprise field sales supported by an IndiaMART B2B marketplace presence and a direct inquiry website funnel, with an installed base of 250+ ESP units for boiler applications and named customers including Steel Authority of India Limited (SAIL), JSW Steel, Sunflag Iron and Steel, Bhushan Steel, and Jayaswal Neco. Revenue mix includes up to 20% exports across 25+ countries including Malaysia and South Africa, with no disclosed external funding or institutional shareholders. Strategic partnerships with INERCO (Low NOx Burners up to 800 MW) and Centre for Engineering & Technology (consulting) extend the offering into gaseous emission control and turnkey project execution.

The company employs 101-500 people, reports annual turnover of 100-500 Crores INR, and has no app, no public API, and no disclosed AI/ML capabilities. Its primary competitive advantages are the HWB-licensed AFGC technology, 30+ years of collective engineering experience, and the ability to re-engineer spares for all makes of ESPs — positioning Unicon as a mid-sized, technically specialized Indian industrial OEM rather than a technology platform company.

Scale indicators10 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• FLSmidth: Global cement and mining equipment major whose air pollution control portfolio (ESP, bag filters, scrubbers) directly addresses Unicon's cement and metals verticals, though its offering is much broader and anchored in capital equipment for larger industrial customers.
• GE Vernova: Power generation and grid technology major with ESP and emissions-control offerings integrated into full boiler island packages; competes with Unicon at the high-end of utility-scale ESP turnkey projects globally.
• ANDRITZ: Diversified industrial and environmental technology group with air pollution control and fabric-filter solutions for power and process industries; overlaps with Unicon's bag-filter and ESP portfolio at the larger-project tier.
• Babcock & Wilcox: Global power-generation technology company supplying ESPs, scrubbers, and emissions-control retrofits to coal-fired utilities; competes in the same thermal-power retrofit and new-build ESP market Unicon serves across India and exports.
• BHEL: India's largest power equipment OEM, supplying ESPs, scrubbers and complete emission-control packages for thermal power plants; competes with Unicon for the largest Indian utility and SAIL-class turnkey contracts.

Direct peers

• Thermax Limited: Indian-listed EPC and OEM with a dedicated air pollution control business supplying ESPs, bag filters, scrubbers and FGD systems to power, steel and cement customers — directly overlapping Unicon's core product lines, verticals, and project execution model.
• Hamon Group: Global air pollution control and heat exchange specialist with deep ESP, scrubber and cooling tower offerings; competes head-to-head with Unicon on utility-scale ESP retrofits and new builds across Asia, the Middle East and Africa.
• Ducon Technologies: US-headquartered APC specialist with significant India operations manufacturing electrostatic precipitators, baghouses, scrubbers and flue gas desulfurization systems — a direct competitor in ESP and particulate-control projects for power and industrial customers.
• Wheelabrator Air Pollution Control: US-based dry and wet APC equipment manufacturer offering ESPs, scrubbers and fabric filters for industrial and utility applications; comparable product portfolio and engineering-led go-to-market model to Unicon's ESP and bag-filter business.

Others

• INERCO: European combustion and emissions technology firm and Unicon's strategic partner for Low NOx Burners; relevant as a technology and channel partner rather than a direct bidder, but adjacent in APC consulting and combustion optimization.
