Wacker Neuson 1000236661 Round Nozzle

The Wacker Neuson Round Nozzle is a genuine OEM component designed for the TH627 indirect-fired air heater. As a factory-sourced part, it is manufactured to the exact specifications required by the TH627, ensuring proper combustion airflow and heat output performance. If your heater is showing uneven flame pattern, reduced heat output, or signs of nozzle wear, the is the correct replacement to restore proper operation.

Key Features

• Genuine OEM Combustion Accuracy — manufactured to the precise orifice geometry required for correct fuel atomization and stable flame pattern in the TH627 burner assembly.
• Direct-Fit Replacement — engineered to drop into the existing burner head position of the TH627 without additional adjustment or adaptation.
• Confirmed TH627 Fitment — verified against the official Wacker Neuson spare parts list for the TH627 indirect air heater (418-02).
• Sustained Heat Output — a correctly functioning round nozzle maintains consistent fuel delivery, supporting rated BTU output and efficient indirect heating performance on the jobsite.
• Fuel System Safety — worn or damaged nozzles can cause incomplete combustion, fuel misting, or flame instability; replacing with the correct OEM nozzle restores safe and controlled burner operation.

The round nozzle is a critical component in the burner assembly of an indirect-fired air heater. It atomizes diesel fuel into a fine spray, which then mixes with combustion air to produce a stable, controlled flame inside the heat exchanger. When the nozzle wears or becomes clogged, fuel atomization deteriorates — leading to hard starts, sooty exhaust, inconsistent heat output, or burner lockout. Replacing it promptly keeps the heater running cleanly and efficiently.
