Retrofit Emission Control Device (RECD)

We are leading a new generation of emission control with our CarbonFree™ RECD—India’s only truly filter-less Retrofit Emission Control Device—designed to significantly cut harmful pollutants from diesel generators. Backed by ARAI certification, CarbonFree™ RECD offers an ideal solution for industries aiming to meet strict environmental standards while enhancing operational efficiency.


Unrivalled Power

Reduce dangerous emissions (NOx, CO, and particulates) by up to 90% for safer, cleaner operations.

No hassles, No filters, 

A filter-less design reduces unscheduled downtime and does away with consumables.

Economical

Reduce maintenance and increase the lifespan of DG set—strong ROI right away..

Eco‑Friendly

Reduces your carbon footprint significantly, which aids in achieving sustainability goals.

Future Compliance 

Use scalable technology to stay ahead of the increasingly strict emission regulations.


Accredited Performance

You can audit independently tested and ARAI-approved for dependability.


CARBONFREE-RECD

Through the development of "Carbonfree", offers a Filter-Less solution as a RECD (Retrofit Emission Control Device) that reduces harmful Carbon emissions and captures more than 92% of particulate matter from the diesel generator set without alteration in the existing systems. We ensure our customers that complies to the recent CPCB norm seemlessly as ARAI has approved us for CPCB I and CPCB II Diesel Generators irrespective of the manufacturer.


Let's Evolve together in a sustainable way. 


--Lifespan of 20 Years
--Filter-less EPSD-based
--No Choking
--Cost-Effective
--Long life for the diesel generator
--No Maintenance & Manual Cleaning

How Carbon Free RECD Works
​Unmatched clean air through a smooth, filter-free multi-stage procedure.

1.Gas Inlet

Exhaust gas enters directly from the generator.

2. Particle Charging

A corona discharge charges fine particles for efficient removal.

3. Electrostatic
Collection

Charged particles adhere to collection plates, trapping pollution.

4.Clean Gas Exit

Purified air is released back into the atmosphere.

5.Clean Gas Exit

Purified air is released back into the atmosphere.
