Reach your sustainability goals with our Tier 4 Final environmentally friendly generators

As the Canadian Environmental Protection Act (CEPA) and the United States Environmental Protection Agency (EPA) embed strict new standards for diesel generators and engines, compliance with Tier 4F emission standards is an obligation, not an option.

Developed for emission reduction, our range of Tier 4 Final generators is built to support your path to a more sustainable, less harmful future. Across our environmentally friendly generators, we’ve taken a considered approach to design, addressing key pollutants and Tier 4 Final emissions identified by the EPA. These include NOx, particulate matter, CO, and CO2–all regulated emissions that we significantly reduce.

Choose an Aggreko clean power generator for:

  • 98% less particulate matter than other generators
  • A 96% reduction in NOx emissions
  • Generators optimized for Tier 4F emission standards

Aggreko is setting the rental industry-wide standard in low-emission, clean power generators

With models ranging from 100 kW to 500 kW, we offer the biggest Tier 4 Final generator fleet in Canada. Whatever your applications, on any scale, we can help.

At the same time, we provide the complete care and support it takes to keep your project and site up and running. It’s not just a quiet, efficient generator but the combination of industry-leading equipment, constant monitoring, and help every step of the way from implementation to ongoing maintenance.

FAQs about Aggreko's Tier 4 Final generators

What is Tier 4 Final?

Tier 4 Final is a set of emissions standards around non-road diesel engines like those used in generators. With diesel being a common source of pollutants like nitrous oxide and particulate matter, setting regulated standards for emissions is an important way to make power generation less harmful to the environment.

TIER 4F Engines Produce 96% Less NOx AND 98% PM Emissions than Tier 1 Engines

How do Stage 5 vs Tier 4 Final differ?

Stage 5 or Stage V is a set of European emission standards for diesel engines, focusing on similar emissions and pollutants to Tier 4 Final. It’s not a case of Stage 5 vs Tier 4 Final, but two closely related sets of expectations, applying to different regions around the world.

What emissions are regulated?

The overarching goal of the EPA is to reduce emissions across all engines, partly through innovation and encouraging the market to design new solutions. Previous implementations of the standards have focused on a reduction of carbon monoxide (CO) and particulate matter emissions. However, Tier 4F also emphasizes stringent demands on reducing NOx (causing acid rain).

How do we reduce emissions with Aggreko low-emission generators?

Installed and monitored by our experts, our Tier 4 Final generators deliver low-emission power generation through improved technology.

Across our range, you’ll find features including:

  • Diesel particulate filter to reduce particulate matter
  • Selective catalytic reduction system to reduce NOx emissions
  • Diesel oxidation catalyst to reduce CO emissions through oxidization
  • Low noise with variable-speed fans to reduce sound at lower loads – ideal for urban areas
  • Arc flash detection and physical safety barriers to protect operators
  • Internal Diesel Exhaust Fluid (DEF)/AdBlue tank matches to internal fuel capacity – so the DEF only needs to be filled when the fuel tank does
  • External DEF/AdBlue tank options to extend on-site refill intervals, supply multiple generators, and reduce site installation footprint

The whole fleet across an entire project must be monitored. Our remote monitoring lets you optimize, control, and manage your on-hire fleet with ease.

Talk to Aggreko today to see how we can help you with:

  • Lower emissions to reach Tier 4 Final emissions standards
  • Reduced controlled emissions bringing NOx, CO2, and VOCs to near-zero levels
  • Reduction in harmful particulates
  • Reduced fuel usage and costs – saving money on your bottom line
  • Low noise for environments like urban centers and residential spaces
  • Fast installation and commissioning – just plug and play with the entire Aggreko ecosystem
  • Faster, more secure setup with extended fuel and DEF fill intervals
  • Actionable insights with Aggreko Remote Monitoring (ARM) to optimize your fleet, backed by our Remote Operations Center (ROC)
