Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and pressure specifications, ensuring the hose assembly handles the thermal and flow demands of diesel indirect-fired heating systems.
- Direct Drop-In Replacement — Matches the original hose routing, end fittings, and connection points on the HI 770 XHD, allowing a straightforward swap without custom adaptation.
- Broad HI 770 XHD Compatibility — Fits both the standard HI 770 XHD (1x16) and the Arctic Bear XHD (2x12) indirect air heater variants, covering the full XHD platform.
- Sustained Heat Output — A sound, leak-free hose assembly maintains consistent fuel or fluid delivery through the heating circuit; a cracked or failing hose can cause output loss or unplanned heater shutdowns on the worksite.
- Fuel System Integrity — On diesel indirect-fired heaters, hose condition is directly tied to safe, consistent burner operation — using a correct OEM replacement helps maintain proper system sealing and flow integrity.
In an indirect-fired diesel air heater like the HI 770 XHD, the hose complete forms a critical link in the fluid or fuel circuit, routing diesel or combustion-related fluid between system components under heat and pressure cycling. A properly functioning hose maintains uninterrupted flow and a sealed circuit, supporting consistent burner performance and heat output. When a hose cracks, softens, or develops a leak, it can disrupt fuel delivery or fluid circulation, leading to reduced heating efficiency or a complete heater shutdown — making timely replacement essential for continuous cold-weather operations.
