The Wacker Neuson 4.5GPH 60 Degree B Nozzle is a genuine OEM component designed for the HI750, HI260, and HP252 indirect fired air heater series. As a factory-sourced part, the is manufactured to the exact flow rate and spray angle specifications required by Wacker Neuson heater systems — ensuring the burner receives the correct fuel delivery every time. This nozzle is confirmed to fit a wide range of HI750 configurations including diesel, gas, and surge-protected models, as well as HI260 oil-fired and HP252 heater units. When it's time to restore peak combustion performance, replacing the nozzle with a genuine OEM part is the straightforward, no-compromise solution.
Key Features
- Correct Flow Rate and Spray Angle: — Rated at 4.5GPH with a 60-degree B spray pattern, matching the original burner calibration for consistent fuel atomization.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, this nozzle meets the same material and dimensional standards as the nozzle installed at the factory.
- Broad HI-Series Compatibility: — Fits HI750 diesel, gas, surge-protected, and skid-mounted variants, plus HI260 oil-fired heaters and the HP252 heater — covering multiple configurations with one part number.
- Restores Clean, Efficient Combustion: — A worn or clogged nozzle causes uneven fuel spray, sooting, incomplete combustion, and loss of heat output; replacing it with a correctly rated nozzle brings burner performance back to spec.
- Fuel System Safety: — Correct nozzle sizing is critical in oil-fired and diesel heater systems; an improperly rated nozzle can cause over-fueling, flameout, or hazardous operation, making the use of the specified OEM part essential.
- Direct Drop-In Replacement: — Designed to thread into the same burner assembly position as the original, using the existing fuel line connection with no adaptation needed.
A burner nozzle in an indirect fired air heater is responsible for atomizing fuel into a fine mist that can be ignited cleanly and efficiently inside the combustion chamber. The flow rate — measured in gallons per hour — and the spray angle together determine how much heat the heater can produce and how evenly the flame burns. When a nozzle becomes clogged, worn, or incorrectly rated, it disrupts fuel atomization, which leads to sooting of the heat exchanger, erratic ignition, reduced heat output, and in some cases a complete burner lockout — leaving a jobsite without heat when it's needed most.
