Retrofitting of Emission Control Devices

We are providing solutions for emission control, in line with the recommendations of NGT and State Pollution Control Boards. We are providing type approved retrofits for Diesel Generators as per the notification of the CPCB and respective pollution control boards.

A revolutionary innovation which is rated as one of the best technologies globally to reduce air pollution.

A solution that supports the environment enabling particulate matter (pm) reduction on diesel powered generators captures PM with more than 70% efficiency SPL in agreement with Pi-Green, introduces a pioneering filter less technology for PM reduction for Diesel Genset(s). The Pi-Green Retrofit Emission Control Device (RECD) is based on filter-less technology and is highly efficient in improving air quality. These RECDs are compliant with the NGT order dated 6th August 2019 in O.A 681/2018 as declared by the manufacturer*. It uses Electrostatic Precipitation (ESP) to enable sub-micron particulates to get collected at opposite- charged surfaces and form into larger clusters through the process of agglomeration. The collected soot is removed at optimal intervals using a patented scraping mechanism.

Technology comparisons and advantages: ∙ RECD is installed after the diesel genset muffler without disturbing the existing setup ∙ Exhaust gases enter RECD and are confronted with electrical discharge created through high voltage DC field ∙ Passing through the field, particulate matter acquires electrical charge and is attracted to the oppositely charged electrode ∙ PM gets agglomerated on the collector electrode and forms substantially higher particle-size clusters ∙ Agglomerated PM is periodically scrapped and collected using a patented mechanism for environmentally safe disposal∙ Robust component build with stringent quality requirements ∙ Genset-like bedframe-based installation, protection from environmental factors such as heat-resistant paint on internal units, galvanized and powder-coated sheets and structural members for enclosure, thermal management for power and control unit, well-designed seals and interfaces Installation aspects: ∙ Installation checklist as well as pre-order site survey for feasibility (for larger independent installations)

Long-term performance durability with no wear-out components ∙ No chemicals therefore minimal ageing, carefully designed routings, forced cooling wherever required, redundancy in cooling arrangement, adequate service protocols to maintain efficiency ∙ Optional installation of sacrificial electrodes for very corrosive environmental applications (Coastal applications)
