Get Ready for The Biofuel Transformation with Danfoss Bio Products

DCS Get Ready for the Biofuel Transition with Danfoss Bio Produts 1a 400x275f

August 17, 2022


Danfoss expands its line of reliable high-quality burner components with new Bio30 pumps and HVO nozzles designed to help customers decarbonize and lower heating emissions.

Transitioning to liquid low-carbon fuels is an important part of of the CO2 decarbonization journey. Many of these fuels, which are created from different types of raw materials, are already available and will contribute significantly to climate protection together with modern oil-fired condensing boilers. Until now, the challenge has been getting biofuels to the boiler. Danfoss has taken up this challenge, by making its pumps and nozzles biofuel ready.

Solving the corrosion challenge

Traditional pumps often contain copper or copper-containing metals, for example brass. Independent research has shown that contact between parts made of brass and biofuels should be avoided. When biofuel contacts this type of non-ferrous metal, it oxidizes and polymerizes. The fuel’s acid content increases and it becomes more corrosive. The fuel will then react with these metal parts in the pump, which can adversely impact pump performance, cause leakage or lead to the safety function (e.g., solenoid valve) failing. 

Additionally, the combination of copper-containing parts and higher temperatures harms the biofuels, because of the internal circulation process. The fluid passes these parts several times, thereby reducing the biofuel’s stability and causing the fuel to degrade. To prevent this from happening, manufacturers would have to replace the parts yearly or every second year.

Ina Corneliussen, Product Manager, Burner Components, explains how the new biofuel ready pumps address this challenge.

 “We have been working with biofuels for over 15 years, and we have always prioritized safety. That’s one of the reasons we’ve changed the brass components in our Bio30 pumps to make sure all product components are biofuel compatible. And our well-known mechanical shaft sealing secures the highest quality and helps eliminate the risk of oil leakage and product malfunction.”

TUV-certified to work with biofuels

Danfoss has conducted extensive in-house and field testing to develop our product portfolio, working closely with customers and independent competence centers to ensure the components’ compatibility with biofuels. After successful product testing, we acquired a TUV certification in 2021. 

“Some of the largest OEMs are already using our new pumps and have approved them for their applications, and we can see that more of our existing customers are interested in switching to Bio30 pumps. For example, effective July 1, 2022, France has changed its regulations to only install Bio30 ready products in their boilers,” comments Stefan Spornberger, Senior Quality and Application Manager, Burner Components. “We’re pleased to support our customers decarbonization efforts by providing them with best-in-class solutions for transitioning to carbon-neutral energy sources.”

Nozzles ready for the HVO market

The expanded portfolio of bio products also includes HVO nozzles, which have been adjusted and are now fully compatible for biofuel use. These nozzles are designed for domestic oil burners in the UK and enable them to use hydrotreated vegetable oil (HVO) derived from used cooking oil or non-food vegetable oils. 

Removing barriers to the net zero transition

By developing biofuel ready components, Danfoss aims to support the transition to low-carbon liquid fuels. “Over the past 75 years, Danfoss has built a reputation within the industry for designing and manufacturing high-quality, reliable products. And our customers can expect that same standard from our new line of bio products,” says Ina Corneliussen. And we will continue to develop our Bio portfolio to design products that can enable boilers to run on higher contents of biofuel.”

Conserving Power and CO2 Emissions with Premium Efficiency Motors

The process of converting electrical energy to mechanical energy is never perfect. As much as we would like to have a 100% efficient motor, it is impossible to build a machine that will take 746 watts of electricity (the equivalent of 1 Hp) and convert it to 1 Hp of mechanical output. It always takes somewhat more than 746 watts to yield 1 Hp’s worth of output.

Motors are continuously being pushed to be more efficient and reduce these losses. Over the years the guiding regulations of motor manufacturing have pushed us to improve efficiencies to new levels to reduce the considerable global power consumption of motors, as they are everywhere. From our factories, utilities and homes and most anywhere you can think of.

How much power consumption aka money are you spending that you do not have to? Take a minute while having your coffee to see if you can save money.
