Each system is designed with reliability, energy efficiency, and ease of maintenance at its core, ensuring long-term performance in the most demanding industrial environments.
Air Pollution Control Systems (APCS)
We design and install pollution control systems that help industries meet environmental standards while improving workplace safety. Our APCS solutions remove dust, fumes, and secondary emissions from furnaces and other processes, protecting both equipment and people.
What We Do:
Design and supply Bag Filters, Venturi Scrubbers, and Cassette Filters.
Dust Collection Systems for furnaces, slag handling, and casting operations.
Stack monitoring systems with CPCB/USEPA-compliant measurement methods.
Screw conveyors for efficient dust handling and safe disposal.
Forced Draught Coolers for gas cooling from 1200°C to 250°C.
Water Treatment Plants (WTP)
Steel plants consume massive amounts of water for cooling, dust suppression, cleaning, temperature regulation, and waste transport. This generates large volumes of wastewater with suspended solids, dissolved chemicals, and impurities. Our advanced Filtration & Treatment Plants are designed to recycle and purify water in Continuous Rolling and Continuous Casting Mills, ensuring efficiency, compliance, and cost savings.
Advantages:
Reduced Turbidity & TSS – Cuts pump and pipeline maintenance by over 50%.
No Scaling or Fouling – Extends equipment and pipeline life significantly.
Longer Roller Pass Life – Increases by 20–25%, boosting profitability.
Less Frequent Draining – Annual draining instead of every 2–3 months saves costs.
Improved Cooling Tower Efficiency – Higher heat transfer rates, reduced power consumption, longer life.
Reduced Scale Formation – Prevents nozzle choking and corrosion in caster machines.
Industrial Air Conditioning Unit (I-AC)
Our Industrial Air Conditioners are engineered to cool panel rooms and maintain safe operating temperatures for PLC banks and control panels. Designed in-house, these units perform reliably even in highly dusty and demanding industrial environments, ensuring continuous protection of critical electrical systems.
