Upgraded extended length combustion chamber creates sufficient combustion space. Under 6KW high power working condition, diesel burns more completely, effectively reducing carbon buildup and exhaust residue and prolonging service life.
Equipped with dual brushless motor and smart inverter module, the unit adjusts power output dynamically following coolant temperature. It achieves up to 33% fuel saving compared with old style liquid heaters.
Built in overheat and low voltage protection guarantee reliable performance in severe low temperature environment. Compact structure enables simple installation without massive vehicle reconstruction.
A: Longer combustion cavity supports full fuel combustion under high power load. It minimizes carbon deposit, lowers failure rate during long‑time continuous running, which is especially critical for 6kW high power heating requirements.
A: Yes. It circulates heated coolant through vehicle liquid circuit. It pre-heats engine meanwhile supplies heat to RV living compartment within one integrated heating system.
A: The 6kW variant targets large volume vehicles. Compact vans and small campers are better fitted with 5kW model. Choose 7kW for heavy trucks, large motorhomes and engineering machines with large heat loss.
A: It lowers internal mechanical friction. Co-working with inverter control, it avoids continuous full‑power operation, cutting fuel consumption and noise for overnight running.
