Cleaner DG Set Operations: When to Consider RECD and Dual Fuel Solutions

An overview of two retrofit-oriented approaches that can help facilities think more clearly about diesel-generator emissions and fuel use.

This article is designed to help facilities frame the right questions early, before moving into detailed design, technology selection or implementation planning.

Understand the operating challenge first

Diesel generators support critical backup power in many facilities, but their operational impact can include exhaust emissions, fuel consumption and maintenance requirements. The first step is to understand the generator capacity, loading pattern, location and operating hours.

This context helps determine whether the primary challenge is emission reduction, diesel dependency, site exposure or a combination of factors.

RECD addresses exhaust-emission control

A Retrofit Emission Control Device is installed in the exhaust line to support reduction of particulate matter and other pollutants, depending on the selected technology and application. It can be considered where cleaner exhaust performance is an important operational objective.

Compatibility, exhaust layout, temperature conditions and access for maintenance are key parts of an effective retrofit review.

Dual fuel solutions focus on diesel displacement

A dual fuel kit is designed to allow an existing diesel generator to operate with diesel and a methane-rich gas source in a controlled combination. The application needs to consider gas availability, safety, generator compatibility and performance expectations.

The solution focus is different from exhaust treatment: it is primarily about fuel strategy and operating economics, alongside potential environmental benefits.

  • Generator rating, condition and loading profile
  • Site-specific emission and fuel-use objectives
  • Gas supply availability and operating safeguards
  • Installation, commissioning and maintenance planning

Use a structured retrofit assessment

A strong retrofit decision connects equipment selection with site conditions. This includes technical evaluation, integration planning, installation access and a clear support plan after commissioning.

The right solution is the one that the facility can operate safely, maintain consistently and align with its broader environmental objectives.

Key Takeaways

Make the next decision with clearer context.

01

Define whether the key objective is emission reduction, fuel strategy or both.

02

Review generator capacity, loading and site conditions before retrofitting.

03

Plan commissioning and maintenance as part of the solution—not as a separate step.
