RECD vs DPF: Understanding Differences, Similarities With Features

In today’s rapidly evolving world, the demand for energy is at a high level. Retrofit Emission Control Device (RECD) are the complete CPCB-approved systems installed on diesel generators to reduce pollution. On the other hand, the diesel particulate filter (DPF) is a core component for filtering out more than 90% of matter. There are the power sources available for RECD and DPF, which include industries, businesses and homes like diesel generators that run smoothly. In this blog, we discuss differences and similarities of RECD and DPF with its key features. However with the increased demand of diesel generators it comes with a significant environmental concern. The emissions produced by these generators release harmful effects on our environment, health and overall life.

In addition, Retrofit Emission Control Devices are the system which is controlled for older generators and DPF is a component based filter machine. These devices can reduce the particulate matter emissions by 70-90%. Moreover, we discuss its pros and cons of RECD and DPF, which regulate the emission impact on the environment or nature.

What are RECD and DPF?

What is RECD?

It is a pollution control technology installed on the exhaust system of diesel generator sets to reduce harmful emissions. These emissions are involved, which are particulate matter (PM), hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx). Moreover, they mainly act as filters or catalytic converters, which enable older engines to meet strict air quality standards.

Various Aspects of RECDs

There are various aspects of RECD available which are.

• Functionality: Its functionality is to capture and neutralize pollutants from exhaust gas before it is released.
• Efficiency: They can reduce the particulate matter by 70% to 90%.
• Applications: The primary use for the applications used on DG sets, which are 125kVA to 1000kVA and sometimes it is raised higher to comply with pollution control regulations.

What is DPF?

DPF are crucial in reducing emission from diesel vehicles by trapping soot and ash. They are made from a ceramic material and require periodically to burn off the accumulated soot. It is essential for maintaining the filter’s functionality. DPF has two types of regeneration: passive and active. However, passive occurs automatically during normal vehicle operation. While the active measures to increase exhaust temperature to burn off soot.

Various Aspects of DPF

These various aspects are functioning, blockage symptoms and maintenance which are.

• Blockage Symptoms: It can cause warning lights, reduced engine power and higher fuel consumption.
• Maintenance: Check the engine which is regularly driving at high speed and using the correct low-SAPS (Sulfated Ash, Phosphorus, and Sulfur).
• Functions: Its function captures the particulate matter more than 90% from diesel exhaust.

Key Differences Between RECD and DPF

The comparison between these two systems highlights the key features and we also discuss the similarities between RECD vs DPF.

Feature	RECD	DPF
Definition	It has complete regulatory-approved assembly.	A specific filtering component with a system provided.
Scope	It covers oxygens like PM, NOx and HC. But it happens when you are using SCR/DOC.	This DPF component mainly focuses on particulate matter.
Maintenance	RECD varies by technology which are passive and active.	Components are high and it needs regular regeneration for clogging.
Best Suitable for	It is best for overall regulatory compliance and emission control.	It is best suitable for reducing visible smoke and black carbon.
Regulatory Status	Its status mandated by CPCB for DG sets in India.	DPF which includes the component to meet the reductions targets.

Similarities Between RECD and DPF

There are various key similarities between the RECD and DPF.

• Both are High efficiency systems.
• They both comply with compliance and regulation.
• Always check for maintenance requirements.
• Both systems are required for construction.
• The main purpose is to reduce emissions.
• Both are used to manage diesel engines.

Which One Is Better, RECD or DPF?

We discuss the RECD and DPF, which one is better in various situations providing the features like emission reduction, fuel consumption and modification.

RECD Device

• The reduction of emission for RECD should be 99.21%.
• In RECD, engine modification is not required.
• No extra fuel consumption.
• Regeneration should be automatic.
• For CPCB approval it ranges from 15kw to 800kw.
• Maintenance cost is less.
• For installation, it takes 4-6 hours.

Standard DPF

• In standard DPF, the emission reduction should be 85-90%.
• Sometimes engine modification is required.
• In this the fuel consumption is approx 2-3% extra.
• The regeneration should be manually active.
• It has limited CPCB approval.
• Installation should take 8-12 hours of time.

Moreover, the RECDs are better for existing industrial diesel generators as compared to DPF.

Understanding Pros and Cons of RECD and DPF

Take a look at the advantages and disadvantages of RECD and DPF.

Advantages and Disadvantages of RECD

Conclusion

In conclusion, we hope you understand the difference between RECD and DPF with its key differences and similarities. In this blog, we discuss the various aspects of RECD and DPF with different comparisons of these generators. However, a DPF is a key component within many efficient RECD systems. In addition the RECD itself is the main component which completes the solution for upgrading existing or older diesel generators. This page also includes which is better for convenient use, there are two generator support systems. The Automoto RECD and Standard DPF in which RECD gives better performance and it is also good efficient for diesel generators.
