The Danfoss oil nozzles

Monday, May 17, 2021

Heating oil as a closed liquid cannot burn until the liquid has evaporated or breaks down into small particles close to evaporation. In order to achieve this, a special device is required, the pressure atomizer nozzle, or in short the oil burner nozzle.


The "birth" of the oil burner nozzle dates back many decades. The function and the physical conditions have not changed but the required throughputs of the nozzles are continually decreasing as our energy awareness’ for lower consumption and energy-conscious heating has continued to increase. Further steps can also be expected in the future, as the requirements for energy savings and efficiency will continue to increase.

The pressure atomizer nozzle has been known on the market for decades as a reliable product, and since today smaller nozzle performances can only be achieved through smaller slots and holes inside the nozzle, there is a risk that this level of reliability will be destroyed by dirt sensitivity in these small cross-sections.


The wide range of Danfoss oil nozzles (steel or brass) includes stationary, private and industrial burners. The nozzles are designed for conventional heating oil/kerosene and are available in all spray patterns and angles. An anti-drip valve (LE) is also optional. Throughput ranges from 0.2 to 35 USgal/h.

The following features make Danfoss nozzles unique:

• Excellent spray pattern and absolute reliability
• Tightest tolerances in throughput, spray pattern and symmetry
• Each nozzle is 100% tested on all functional parameters
• Danfoss oil nozzles are freed from the test oil

Good to know: In a series of tests carried out by TÜV Rheinland (Report No. S 221 2014 S4 ) 34% of the most common oil burner nozzles failed.
