Does a 750 kVA DG set need an RECD?
Under CPCB guidance, older diesel generator sets that do not meet the latest CPCB IV+ norms are expected to cut particulate emissions by at least 70% with an approved retrofit device. Several states and the Delhi-NCR region apply this to DG sets from 125 kVA upwards, and some extend it to smaller sets.
Your state pollution control board's latest circular decides the exact obligation and deadline for your site.
Which Novorbis device fits
- CarbonFree ESP: filterless electrostatic capture, no filter replacements and very low back-pressure.
- CarbonFree Advanced Catalyst+: catalyst plus particulate control for PM, CO and hydrocarbons.
- The final choice depends on engine model, duty cycle, exhaust layout and available space, confirmed at the site survey.
How the retrofit works
- Site survey: engine details, exhaust route, space and load profile.
- Device selection matched to the approved capacity range.
- Installation, usually completed without long DG downtime.
- Testing and the documentation your inspector will ask for.
- AMC and remote monitoring for ongoing compliance.
Frequently asked questions
Is the Novorbis RECD approved for 750 kVA DG sets?
Novorbis Itus is on the CPCB RECD vendor list (as of 30-06-2026) with ARAI certification covering several capacity ranges. Ask us for the certificate that matches your 750 kVA set.
Will an RECD affect my generator's performance?
Novorbis devices are designed for low exhaust back-pressure so the generator keeps running normally. The site survey confirms the fit for your engine.
How long does installation take?
Manufacturing to installation is typically completed within about a month, depending on equipment and site conditions.
