  • Save Fuel,
    ​Lower Emissions

    We use proven technology to reduce fuel use and emissions in diesel generators.

Rentar Fuel Catalyst with fuel lines

The Technology

It is a small cartridge that screws into your fuel line and contains rare earth catalysts that change the molecular structure of some of the fuel constituents to give a cleaner and more efficient combustion. No magic or magnets, just chemistry and physics.

​The Results

Reduces Fuel Consumption 5% - 7%

Independent labs and customer-run tests have shown fuel savings from 3% to as high as 12%. We see an average of 3% to 12% for most genset applications. We have many test results we can share with you. Results may vary based on the application, type of engine, and the type of fuel used.

Calculate My Savings

Lowers Emissions Up to 50%

Results vary because it's super complex, but we've seen soot and PM lowered >50%, NOx, CO & CO2 lowered >40%, VOCs lowered >60%. We have many independent test results we can share with you. Go see the Emissions page. Results may vary based on the application, type of engine, and the type of fuel used.

Calculate My CO2 Reduction

Extends Engine Life

This is a major cost saver of producing less PM or soot in the combustion process. The soot acts as tiny charcoal briquettes that wear away your engine parts like piston rings, cylinder liners, etc. We don't promise a number but we've had customers go 50% longer between engine overhauls (top end and full).

Extends Oil Change Intervals

This is one of several hidden benefits of reducing Particulate Matter (soot or black smoke) and VOCs in the combustion of the fuel. If you're making less soot and VOCs to get into the oil, it will last longer between changes. Results will vary but we recommend changing oil by analysis, not by hours.

Extends DPF Regen Intervals

Less soot means longer time between required DPF regenerations. Regenerations cost fuel, and the fewer you do, the less fuel you waste doing it.

Lower emissions AND save fuel?

We have the only technology we know of that reduces emissions while saving fuel. Most methods of lowering emissions increase fuel usage but if you alter the fuel before you burn it, it burns more efficiently - meaning less fuel wasted and lower emissions from the combustion. It's a very different way to tackle the problem and get the double benefits.

Some of Our Customers

Why Zelkam?

We have become a leader in applying this technology to the diesel equipment industry. Brian Livingston, our president, is an experienced Chemical Engineer that spent almost 20 years in Caterpillar's Diesel Engine Division. He combines his decades of experience with Rentar's 20-year history to provide expert advice and guidance on this unique technology. We have saved customers millions of liters of diesel and many thousands of tons of CO2. Reach out and have an honest conversation with him about it and what it could mean for your operations.

What Is This Technology and How Does It Work?

As fuel passes over the rare-earth metals in the device, it catalyzes some reactions in the fuel that increase its ability to burn more efficiently. The catalysts mainly do two things to improve the fuel for better combustion: 

  1. "Crack" longer chain hydrocarbons into shorter chains that burn easier and cleaner
  2. Take straight-chain hydrocarbons and turn them into ring compounds that generate free hydrogen, allowing the mixture to burn more efficiently.

Both of these allow for a faster and cleaner burn in the combustion chamber, increasing the efficiency. It's not magic or magnets, just chemistry and physics. We have a section on "How It Works" where we go as deep into the science of it as you want to go! Understanding the chemistry and physics of this technology really helped us become believers in it. If you slept through chemistry class, that's OK, we've got you covered!

30-Minute Installation

It mounts in the fuel line, just before the injection pump. Detailed instructions are on the Installation page.

It also works with high-pressure common rail fuel systems. See the installation page.

Testing This Technology On Your Fleet

Many customers are skeptical at first. We can relate. We offer great testing & validation support.

We have helped many, many customers in all types of equipment fleets test these catalysts. It's done with almost NO disruption to your operations in as little as 250 hours of normal operation. We help you design the test to get statistically valid data to base your investment decision on. Contact us and let's talk about that.

Gensets usually see a 3%-12% fuel savings. We've seen as high as 31%. Results will vary with fuel, conditions, engine, etc.
What About Emission Reduction?

Let's talk emissions

If emissions are your biggest concern, this technology can reduce emissions at a lower cost than any other technology we know of - and it will quickly pay for itself in fuel savings.

Oh, yah - plenty of those. 

Got Questions?

Sure. Several options: 

The low-touch approach.

The medium-touch approach.

The high-touch approach. We're old-fashioned and like this one the best. We like talking to people!

Hesitant?

We get it. Let's consider 4 points:


Lower fuel consumption, Lower greenhous gasses
