High performance Tier 4 Final generators for ultra-low emissions
Minimize emissions while maximizing performance
Tier 4 Final: Low-Emission Generator Rental
Now you can minimize emissions while maximizing performance.
Setting the standard for low-emission temporary power generators
Aggreko is proud to manufacture and offer the largest fleet of Tier 4 Final-compliant generators in the U.S. and Canada. With models ranging from 25 kW to 1,200 kW in capacity, the Tier 4 Final fleet offers lower-emission power generation with the same high-spec design you can always expect from Aggreko.
Robust and fuel-efficient, our low-noise generators can deliver on your temporary power needs without sacrificing performance, setting a new standard in low-emission energy.
What is Tier 4 Final?
Tier 4 Final is the final phase regulating emissions from new and in-use non-road compression-ignition diesel engines. It aims to reduce emitted harmful substances and is an evolution of previous standards.
What emissions are regulated?
In the US, EPA emissions regulations govern the use of temporary power generators. Some of the key regulations for generators include:
- A 5-stage schedule for emissions reductions on all engines, each of which has driven the development of more complex low-emission engines.
- NOx (Nitrous Oxide) reduction. NOx emissions stay in the air for much longer than CO2 and cause acid rain.
- PM (Particulate Matter) reduction. These small carbon particles (also known as soot) are created by incomplete combustion of fossil fuels. They can reduce air quality and impact health.
How to reduce emissions with Aggreko low-emission generators
Installed and monitored by experts, our Tier 4 Final generators deliver low-emission power generation through improved technology with the following features across the range:
- Diesel Particulate Filter to reduce particulate matter (PM)
- Selective Catalytic Reduction system to reduce NOx emissions
- Diesel Oxidation Catalyst to reduce CO emissions through oxidization
- Low noise, with variable speed fans drastically reducing sound at lower loads and in lighter ambient conditions to allow for use in urban areas
- Arc Flash detection and physical safety barriers to provide safety to the operators
- Internal Diesel Exhaust Fluid (DEF)/ Adblue tank matched to internal fuel capacity to ensure that DEF only requires filling at the same frequency as the fuel tank refills
- External DEF/AdBlue tank options to extend on-site refill intervals, supply multiple generators and reduce the required site installation footprint
