1. Reasonable Power Matching, Low Overall Power Consumption
The built-in motor runs at 105W to guarantee stable component operation, while the total power consumption of the whole machine is maintained at 15–33W. Even during long hours of continuous operation or overnight parking heating, it will not cause excessive load on vehicle batteries. This design effectively avoids power loss and ensures normal use of other on-board electrical devices, fully adapting to long-distance travel and unattended working scenarios.
2. High-Efficiency Heat Exchange & Large-Capacity Supporting Tanks
Fitted with an 80-piece heat exchanger, the unit realizes rapid and efficient heat conversion, ensuring steady and sufficient heat output for both warm air and hot water. It is equipped with a 50L water tank to supply ample hot water for daily cleaning, bathing and on-site use. The 38L fuel tank with visible fuel level indicator allows users to check fuel stock at a glance, reducing the trouble of frequent refueling. The complete set of standard spare parts is included in delivery, enabling one-step installation and immediate use without extra accessory purchase.
3. Intelligent Control & Convenient Remote Operation
A smart digital switch is equipped for intuitive display of working status, temperature and running parameters. Users can adjust settings easily on site. The optional 100-meter remote control supports remote start, shutdown and function adjustment, which brings great convenience when the vehicle is parked outdoors or in cold weather. The built-in automatic frequency conversion system intelligently adjusts operating frequency according to ambient temperature and actual load, optimizing working efficiency and extending service life during daily use.
4. Flexible Customization for Diverse Demands
To satisfy differentiated market and application needs, we provide customization services for higher heating power and special structural configurations. Whether for standard vehicle refitting, large engineering supporting projects or special customized equipment, we can make targeted adjustments on specifications and accessories. It is highly adaptable for bulk procurement, project cooperation and personalized modification demands from global clients.
1. Super High Heating Power for Large Spaces
With heating power ranging from 10kW to 12kW, this high-power model is designed for large cabins, spacious RV living areas and mobile work sites. It can quickly raise the ambient temperature and deliver large-volume hot water, solving the problem of slow heating and insufficient hot water supply of ordinary heaters. It works well for group travel, team field operations and long-term on-site residence.
2. Ultra-Wide Temperature Adaptability for All-Climate Use
It operates reliably within the temperature range of -40°C to 80°C. The core components are optimized to resist low-temperature freezing and high-temperature aging. It maintains stable performance in severely cold northern regions, dry hot areas and humid coastal zones, supporting all-season normal operation for global users.
3. Controlled Fuel Consumption, Cost-Effective for Long-Term Use
Running on diesel fuel, the fuel consumption is kept at 0.8–1.1L per hour. Despite its high heating output, it maintains economical fuel cost. For fleets running long routes and field teams working around the clock, it effectively cuts daily operating expenses and delivers excellent comprehensive economic benefits.
4. All-in-One Integrated Design, Space-Saving & Neat
Combining warm air and hot water supply into a single device, it replaces two separate heating appliances. The compact integrated structure saves valuable interior space of vehicles and mobile facilities, and tidies up pipeline layout. It avoids the messy wiring and installation troubles brought by split equipment, creating a cleaner and more orderly environment for vehicles and work areas.
5. Stable & Durable Performance for Heavy-Duty Use
Built to withstand harsh working conditions, the unit resists vibration, bumping and temperature changes during long-distance travel and outdoor operations. Its solid construction delivers consistent performance during prolonged continuous operation, with low failure rates and little routine maintenance required. It is fully capable of serving high-frequency use for commercial fleets and long-term field work.
6. User-Friendly Operation for All Users
The whole system adopts humanized design with simple logic. The digital control panel is easy to learn and operate, requiring no professional skills for daily use. Remote control further simplifies operation in cold or inconvenient environments. From individual users to professional maintenance teams, everyone can get started quickly, greatly improving overall usage experience.
7. Universal Adaptability for Global Markets
The overall design complies with mainstream standards of overseas vehicle refitting and mobile equipment. It is compatible with various types of large vehicles and mobile facilities across different regions. Whether used in cold northern areas, temperate zones or high-altitude field sites, it can adapt to local usage habits and environmental features, enjoying wide recognition in global aftermarket markets.
8. Comprehensive Safety Protection & Reliable Use
Multiple protective mechanisms are embedded to handle unexpected working conditions. The fully sealed structure prevents fuel and water leakage, while intelligent protection functions cut off operation in case of faults. It works safely even when left unattended, eliminating safety worries for overnight parking and remote outdoor use.
