Retrofit for DG Set

Retrofitted Emission Control Device (RECD) for Diesel Generator set

Retrofitted emission control equipments for a diesel generator set is the most efficient way to remove PM concentrations from the exhaust. Our engineers at Vasthi Instruments have designed and developed retrofit emission control devices (RECD) for DG sets, in compliance with CPCB 2 norms that can achieve a minimum emission control rate of 90%.

The Retrofitted emission control equipment for a DG set is the most effective way to filter out harmful components like diesel particulate matter (DPM), carbon monoxide (CO), hydrocarbons (HC), sulfur dioxide (SO₂), nitrogen oxides (NOx). Equipping retrofitted emission control equipment (RECD) for DG sets is an immediate and most efficient way to reduce the harmful emissions in the exhaust. A retrofitted emission control equipment for DG set by Vasthi Instruments is highly effective in removing diesel particulate matter (DPM).

While the CPCB mandates an emission reduction of 70%, our engineers at Vasthi have designed retrofit emission control devices for DG sets that can achieve an emission reduction rate of a minimum of 90%. Vasthi Instruments has developed and designed emission control systems for in-use diesel-operated generators with power capacities ranging from 5KVA to 2000KVA based on user requirements.

Ceramic filters to ensure maximum emission control of particulate matter from black smoke and effective reduction of inhalable coarse particles (PM2.5 to PM10)

Retrofit Emission Control Device (RECD) compliance with the parameters set by the National Green Tribunal (NGT), the Central Pollution Control Board (CPCB), and the Commission for Air Quality Management (CAQM).
