Particulate filtration
A diesel particulate filter captures soot and fine particulate matter carried in the exhaust stream, helping reduce visible smoke and particle release.
Cleaner DG exhaust • CPCB-compliance support
Retrofit Emission Control Device for DG Sets
Reduce particulate matter, visible smoke and harmful exhaust emissions from an existing diesel generator with an engineered RECD solution supplied and supported by Gyarash India.

Upgrade the DG set you already operate
A Retrofit Emission Control Device is installed in the generator exhaust line to treat pollutants before exhaust gases are released into the surrounding air. It can help an organisation improve local air quality and respond to applicable pollution-control requirements without immediately replacing a serviceable generator.
Gyarash India supports the project from preliminary data collection and site assessment through product selection, fitment, commissioning and maintenance guidance. The objective is a correctly sized solution that works with the DG set’s exhaust conditions and operating profile.
- Suitable options for ACEGET RECD systems from 25 kVA to 1000 kVA
- Designed around the generator’s actual exhaust flow and available space
- Support for documentation, installation planning and handover
- Service guidance for long-term system performance
*Performance note: Emission-reduction results vary with DG-set health, load, operating temperature, diesel quality, maintenance and environmental conditions. A technical assessment is required before selection.
How the system works
Layered filtration and catalytic treatment
The RECD is engineered to manage the pollutants typically present in diesel exhaust while maintaining the airflow required for dependable generator operation.
Catalytic oxidation
A diesel oxidation catalyst supports the conversion of carbon monoxide and unburned hydrocarbons into less harmful compounds under suitable operating conditions.
System monitoring
Temperature and pressure data can help technicians assess operating conditions, back pressure and maintenance requirements during the product lifecycle.

Business value
Why organisations retrofit emission control
A well-selected RECD is more than an exhaust accessory—it supports cleaner operations, responsible facility management and a more practical compliance pathway.
Lower exhaust pollution
Control particulate matter, smoke, carbon monoxide and hydrocarbons at the DG-set exhaust source.
Support regulatory readiness
Use documented, approved technology as part of the organisation’s response to applicable emission-control directions.
Retain an existing DG set
Upgrade a suitable generator instead of immediately replacing the entire backup-power asset.
Improve the site environment
Reduced smoke and particulate release can help create a cleaner environment around generator installations.
Site-specific configuration
Sizing, duct routing, foundation, back pressure and access are evaluated for the actual installation.
Lifecycle assistance
Receive installation coordination, commissioning guidance and planned service support from one team.
Project workflow
From DG details to commissioned system
A structured technical process reduces fitment risk and helps align the selected RECD with the generator and site.
Share DG information
Provide generator make, model, kVA rating, engine details, installation photographs, load pattern and operating hours.
Technical assessment
The team reviews DG condition, exhaust routing, space, access, foundation, electrical supply and site constraints.
Supply and installation
The selected system is positioned, connected to the exhaust line and integrated with the required sensors and controls.
Commission and support
Operating checks, documentation, user guidance and the recommended inspection schedule are provided at handover.

Compliance-conscious approach
Use approved technology with proper project documentation
ACEGET presents its RECD range as tested and approved under CPCB system procedure PCLS/12/2021-22 and aligned with CAQM Direction No. 76. The appropriate compliance action for a particular DG set can depend on its manufacturing date, capacity, location, usage and the directions currently applicable to the facility.
Gyarash India helps collect the technical information required for product selection and project documentation. Facility owners should retain invoices, product documents, installation records, commissioning reports and maintenance records for their internal compliance file.

Frequently asked questions
RECD questions, answered clearly
Final suitability and compliance advice should always be based on your DG-set data and current directions applicable to the site.
What does an RECD do?
It treats diesel-generator exhaust using filtration and catalytic technology to reduce particulate matter, smoke and selected harmful gases before they are released into the air.
Can an RECD be installed on an existing DG set?
Yes, subject to a technical assessment. Generator health, kVA rating, exhaust arrangement, available space, operating profile and back-pressure requirements must be reviewed first.
Which DG capacities are available?
ACEGET lists CPCB-approved RECD solutions for DG sets from 25 kVA to 1000 kVA. Equipment above that range may require a different pollution-control-device category and separate assessment.
Will emission reduction always be the same?
No. Published reductions are conditional. Actual results depend on generator condition, load, exhaust temperature, fuel quality, maintenance and site conditions.
Does the system require maintenance?
Yes. Periodic inspection, sensor checks, back-pressure review and filter or system maintenance are important. The exact schedule should follow the supplied product and commissioning documentation.
How do I get the correct model and quotation?
Share the DG rating, make, model, engine plate, manufacturing date, runtime details and clear installation photographs. The technical team can then review the requirement and recommend the next step.
