Danfoss Hago

Danfoss Hago is a brand of precision oil burner nozzles with more than 80 years of history, now manufactured by Danfoss, a Danish engineering and controls company headquartered in Nordborg, Denmark. The Hago brand originated in Mountainside, New Jersey; its NJ manufacturing facility closed in early 2018 with production transferred to a Danfoss facility in Europe. 100% of Danfoss Hago nozzles are factory-tested for spray capacity and pattern accuracy.

Product Lines

• Type A: Hollow cone; fuel concentrated at spray periphery; for hollow-air-pattern burners; up to 2.00 GPH
• Type B (Solid): Fuel concentrated toward center; for high static pressure flame retention burners that specify B pattern; 0.40-12.00 GPH
• Type H (Hollow): Hollow spray pattern; for low firing rates and hollow-air-pattern burners; 0.40-12.00 GPH
• Type S-S (Semi-Solid): Intermediate balanced pattern; general-purpose when burner air pattern is not precisely known
• Specialty types: AH, AS, AB, OD for OEM and commercial applications; full OD range 0.20-35.0 GPH
• Spray angles: 45°, 60°, 80°
• Materials: Stainless steel body; 30-40 micron sintered bronze inlet filter
• Fuel approval: Light and heavy fuel oil, kerosene, HVO biofuels

Why Heating Technicians Specify Danfoss Hago

• 100% factory testing for GPH accuracy and spray pattern per nozzle
• Sintered bronze inlet filter provides final filtration before the orifice
• Four spray pattern types match the nozzle to the burner head geometry specified by the OEM
• 80-plus year history as a primary oil nozzle brand in the US heating market
• Available at HVAC and oil heating supply houses through Danfoss's US distribution network

How to Choose a Danfoss Hago Nozzle

Read the existing nozzle or burner spec sheet for three parameters: GPH firing rate, spray angle (45/60/80°), and spray pattern (A/B/H/S-S). Select the Danfoss Hago nozzle matching all three. If pattern is unknown, use S-S (Semi-Solid). Do not substitute spray angle without confirming it is acceptable for the burner head. Replace at each annual service per the burner manufacturer's interval.
