Let's Talk Emissions...

Reduce your carbon footprint

If you use 5% less fuel, you're reducing that part of your carbon footprint by 5%.  (And you save 5% fuel costs at the same time).

Reduce harmful emissions

Combusting fuel more efficiently inherently produces fewer emissions. This technology can reduce emissions in any engine.

Utilize your older equipment

Do you have to leave some equipment at home for some projects? Are emission restrictions hampering your operations? We can help.

This proven technology lowers your GHG emissions by increasing the efficiency of the combustion. Trucks see a 3% - 5% improvement and larger equipment see a 5% - 7% improvement*.

This technology is available today and can make a difference NOW.

And it pays for itself. Quickly.

 *Results may vary based on the application, type of engine, and the type of fuel used.

Calculate My CO2 Reduction

Test Results Speak

These were all done by independent labs, or by customers, and give you an idea of what has been achieved under those conditions. All conditions are different and will produce a different result. That's why we encourage testing under "real world" conditions - your "real world".

OK - How can we help you check this out?

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 few 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.

City busses benefit greatly from lowering emissions using the Rentar fuel catalyst

Public Transportation

Many city busses around the world have chosen this catalyst device as a way to achieve air quality goals at a fraction of the price of new buses, new engines, or emission retrofits.

School busses benefit greatly from lowering emissions using the Rentar fuel catalyst

School Busses

Many school districts have also opted to reduce their emissions by adding this fuel catalyst device instead of far more costly options.

"We recommend this fuel catalyst for other owners for fuel saving and to reduce greenhouse gas emissions."
