Compliance Is
Opportunity
Environmental compliance is not a burden — it is a business opportunity. Cleaner plants run more efficiently, attract better clients, qualify for green financing, and avoid the operational and reputational risk of regulatory action. JS Engineers builds environment solutions that go beyond minimum compliance — recovering energy, reusing water, and permanently reducing your plant’s footprint.
Air Pollution Control
Pulse Jet Bag Filter Systems
Industry standard for high-efficiency particulate capture from boiler flue gas, dryer exhaust, and process streams. Modular design, online cleaning, low compressed air consumption. Outlet emission consistently below 50 mg/Nm³ — CPCB Schedule I compliant.
- Application
- Boiler flue gas, dryer exhaust, crusher dust, process streams
- Efficiency
- >99.5% particulate removal efficiency
- Outlet Emission
- <50 mg/Nm³ — CPCB Schedule I compliant
- Temperature Range
- Up to 200°C with appropriate fabric selection
- Cleaning Mechanism
- Online pulse jet — no production interruption
- Fabric Options
- Polyester, Aramid, PTFE, PPS — per gas temperature and chemistry
- Controls
- PLC-based pulse controller with differential pressure monitoring
- →Engineering design and sizing — gas volume, temperature, dust load
- →Hopper design — walk-in or standard with level indicators and rotary valves
- →Site installation, structural support, and ductwork
- →Commissioning and performance testing
- →Fabric bag replacement service — supply and installation
Reverse Air Bag Filter Systems
For large-volume, low-pressure applications — kiln exit gas, recovery boilers, high-temperature processes. Lower fabric mechanical stress and superior performance above 220°C where pulse jet systems are unsuitable.
- →High-temperature duty — woven glass fibre and P84 fabric capability
- →Compartment isolation — progressive regeneration without interruption
- →Large gas volume — cement, lime, paper, chemical industries
- →Performance guarantee — outlet emission tested and certified at commissioning
WATER & WASTEWATER
Effluent Treatment Plant (ETP)
JS Engineers designs and builds complete ETP systems for industrial effluents — textile, chemical, food processing, pharmaceutical, and general manufacturing. Consent-compliant treated effluent, minimising environmental liability and enabling water reuse.
Primary Treatment
Screening, equalisation, oil & grease removal, primary settling
Secondary Treatment
ASP, SBR, MBBR, or MBR biological treatment
Tertiary Treatment
Filtration, activated carbon, UV disinfection, advanced polishing
Zero Liquid Discharge
Evaporation and crystallisation — full water recovery
Sludge Management
Thickening, dewatering (filter press/centrifuge), disposal planning
- →Inlet characterisation and treatability study before design
- →State PCB consent compliance — inlet and outlet parameter guarantee
- →Skid-mounted modular ETPs for smaller flow rates
- →Commissioned with performance test and compliance report
Fresh & Waste Water Treatment
From raw water intake to process-ready quality — and from process effluent back to reusable water — JS Engineers covers the complete water management chain.
Heat Pumps
Electrical Heat Pump
Simultaneous process cooling and useful heat recovery — replacing standalone chillers and electric boilers. COP of 3.5–5.0 means 3.5 to 5 units of useful energy per unit of electricity.
- →Cooling capacity 50 kW to multi-MW — scalable modular design
- →Heat recovery for hot water, process heating, space heating
- →R134a, R410A, or natural refrigerant options
- →Energy audit and ROI — typical payback 2–4 years
Hybrid Heat Pump
Combines electrical heat pump with gas-fired backup — maximum efficiency at partial load and reliability during peak demand or utility failure. Ideal for year-round baseload in Indian climatic conditions.
- →Combined gas-electric — best COP across varying load
- →Automatic switchover between electric and gas modes
- →Hot water output up to 80°C for process heating
- →SCADA integration and remote monitoring
Cooling & Heat Recovery Solutions
Closed Loop Cooling Tower
Closed circuit fluid coolers — no process fluid contact with atmosphere. Preferred for sensitive processes.
- →No contamination or fouling risk
- →Lower blowdown vs open towers
- →Glycol circuit for freeze protection
- →Automatic conductivity and pH control
Adiabatic Cooling Tower
Pre-cooling inlet air reduces peak power — ideal for water-scarce regions of India.
- →Media pad or spray nozzle pre-cooler
- →Humidity-controlled activation
- →Integration with air-cooled condensers
- →Annual water savings and ROI analysis
Evaporative Condenser
Combined condenser and cooling tower in one unit — up to 30% smaller refrigerant charge vs air-cooled.
- →6–8°C lower condensing temperature vs air-cooled
- →Legionella risk management plan
- →Winter operation and anti-freeze provisions
Heat Condensation & Recovery System
Every unit of energy lost in flue gas, blowdown, or condenser heat rejection represents money leaving your plant. JS Engineers captures and redirects this energy — reducing boiler fuel consumption, cutting utility costs, and improving overall plant efficiency.
