Vertical All-in-One Unit

Qingdao Donjelion International Trade Co., Ltd. is one of the most credible manufacturers and suppliers of vertical all-in-one unit in China. If you're going to buy customized vertical all-in-one unit, welcome to get more information from our factory. Good service and quality products are available.

The Donjelion Vertical All-in-One Unit represents a thoughtful evolution in diesel air heater design. Unlike traditional heating systems that require separate fuel tanks, pumps, and control modules scattered across your vehicle, this unit consolidates everything into a single vertical enclosure measuring just 500×207×407mm.

At the heart of the system are dual brushless motors-a configuration that delivers two critical advantages. Brushless motors eliminate the friction and wear associated with brushed counterparts, significantly extending operational life while reducing electrical noise that can interfere with sensitive vehicle electronics. The dual-motor setup provides redundancy: if one motor experiences an issue, the second maintains heating output, keeping your cabin warm when you need it most.

The integrated 6L fuel tank is engineered from corrosion-resistant materials and positioned within the unit's footprint to maximize space efficiency. This built-in design eliminates the need for external fuel lines running through your vehicle-a common failure point in traditional installations. With fuel consumption ranging from 0.12 to 0.36 L/h, a full tank delivers 17 to 50 hours of continuous heating depending on the output setting.

The side exhaust configuration is another intentional design choice. By directing exhaust gases laterally rather than downward, the unit can be mounted flush against walls or bulkheads without clearance issues-a practical advantage for installations with limited floor space.

Operating across 12V, 24V, and 220V systems, this unit adapts to virtually any vehicle electrical architecture. Whether you're equipping a 12V truck fleet, a 24V commercial vehicle, or a workshop with 220V mains power, the same unit works across all three.

1.Space-Saving Vertical Design with Hidden Storage

The vertical orientation of this all-in-one diesel heater is not an aesthetic choice-it is a functional decision driven by real-world installation constraints. At 500×207×407mm, the unit's footprint is significantly smaller than horizontal alternatives, allowing installation in tight spaces behind seats, in storage compartments, or against bulkheads. The inclusion of hidden storage space within the enclosure provides practical utility for stowing cables, remote controls, or small tools-a detail that reflects an understanding of how end users actually organize their vehicles.

2.Dual Brushless Motor Reliability

The dual brushless motor configuration delivers a measurable reliability advantage. Brushless motors typically achieve lifespans of 10,000 to 20,000 operating hours compared to 1,000 to 3,000 hours for brushed motors-a 5x to 10x improvement in durability. This translates to fewer service interruptions and lower total cost of ownership over the unit's lifecycle.

3.Ultra-Low Fuel Consumption

With a fuel consumption range of 0.12 to 0.36 L/h, the Vertical All-in-One Unit is among the most fuel-efficient diesel heaters in its class. At the lowest setting, a full 6L tank provides approximately 50 hours of continuous operation-enough for two full days of heating without refueling. Even at maximum output, you get nearly 17 hours of runtime. For fleet operators, this efficiency translates directly into reduced fuel costs over thousands of operating hours.

4.Extreme Temperature Performance

The unit operates reliably from -40°C to 70°C. This wide operating range is achieved through several engineering choices: cold-start fuel preheating ensures reliable ignition in subzero conditions; component selection prioritizes materials that maintain structural integrity across extreme temperature differentials; and the combustion chamber design maintains stable flame characteristics regardless of ambient conditions.

5.Multi-Voltage Compatibility

The ability to operate on 12V, 24V, and 220V systems eliminates the need for voltage converters or separate inventory for different vehicle types. This single-unit flexibility simplifies procurement, reduces spare parts inventory, and ensures that the same heater can be deployed across mixed fleets without modification.

6.Side Exhaust for Flexible Installation

The side-exit exhaust configuration enables flush mounting against walls, bulkheads, or other vertical surfaces. This is particularly valuable in cargo vans, truck cabs, and RV installations where floor space is at a premium and downward exhaust would create clearance or heat-damage issues.

The Vertical All-in-One Unit is purpose-built for mobile and off-grid heating applications where space, reliability, and fuel efficiency are non-negotiable.

• Truck Cabs and Sleeper Berths: Long-haul truck drivers require consistent, quiet heating during rest periods. The unit's ≤70 dB noise level ensures comfortable sleep without the constant drone of engine-idle heating. The compact vertical form fits behind seats or in sleeper compartments.
• Cargo Vans and Work Vehicles: Delivery drivers, mobile service technicians, and tradespeople working in cold climates need their vehicles to remain habitable during loading, unloading, and between jobs. The side exhaust and vertical mounting options allow installation without sacrificing cargo space.
• Recreational Vehicles and Camper Vans: RV owners value systems that are self-contained and easy to operate. The integrated fuel tank eliminates the complexity of external fuel connections, and the multi-voltage operation means the unit works with both 12V house battery systems and 220V shore power.
• Off-Grid Cabins and Workshops: The unit's wide operating temperature range and fuel efficiency make it suitable for stationary applications where diesel is the primary fuel source and grid power is unreliable or unavailable.
• Marine Applications: While not waterproof, the unit's corrosion-resistant construction and compact footprint make it suitable for enclosed cabins on workboats and recreational vessels where space is limited.
