The Wacker Neuson External Cone is a genuine OEM component designed for the HDR 155 Direct Fired Radiant Heater and HDR 45. As a direct factory replacement, this part is produced to the same specifications as the original, ensuring correct fitment and function within the combustion assembly. It is compatible across both the HDR 155 and HDR 45 direct fired radiant heater models.
Key Features
- OEM-Matched Combustion Geometry — Manufactured to the same cone angle and material grade as the original, ensuring consistent flame shaping and combustion efficiency.
- Drop-In Replacement — Engineered to install directly into the burner assembly on HDR series heaters without alteration or adaptation to surrounding components.
- Confirmed Fitment — Verified compatible with the HDR 155 Direct Fired Radiant Heater and HDR 45 models.
- Sustained Heat Output — A correctly fitted external cone maintains proper airflow direction and flame projection, supporting consistent radiant heat delivery in demanding jobsite conditions.
- Fuel System Safety — As a component within the combustion path, using the correct OEM-spec cone helps maintain intended burner behavior and reduces the risk of irregular flame patterns.
The external cone sits at the outlet of the burner assembly on a direct fired radiant heater, shaping and directing the combustion flame to produce focused radiant heat. It works in conjunction with the burner nozzle and air tube to control flame spread and intensity — a correctly formed cone ensures the heater operates at its designed output level. When the cone is damaged, warped, or worn, combustion efficiency drops, flame distribution becomes uneven, and the heater may struggle to reach or hold its rated heat output.
