Product Advantages

 

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.

 

Q: What practical advantages does extended length combustion chamber bring?


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.

 

 

Q: Can this 6kW water heater warm engine and living cabin simultaneously?


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.

 

Q: Is 6kW over-powered for small campers?


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.

 

Q: What makes dual brushless motor better for liquid heater?


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.

We equip this 6kW liquid heater for our European truck fleet. The extended combustion chamber performs reliably in freezing winters. Engine cold‑start wear is greatly reduced. We plan periodic re‑orders for fleet renewal.


Frequently asked questions

Q: Is this parking air conditioner suitable for all types of trucks and vehicles?

A: Our parking air conditioning systems fit most heavy duty trucks, cargo vans, motorhomes, RVs and certain construction vehicles. Before purchase, please verify installation dimensions and confirm sufficient mounting space on your vehicle.

Q: Do I need to drill holes on my vehicle for installation?

A: Extra drilling is usually unnecessary if your vehicle has a factory built sunroof or pre reserved air conditioner opening. For vehicles without reserved positions, limited drilling work may be required. Complete installation guides and diagrams are supplied with every unit.

Q: How long can the parking air conditioner run purely on battery power?

A: Continuous runtime depends heavily on battery capacity, ambient temperature and actual cooling load. As a general reference, a 200Ah battery can support around 6-8 hours of operation under regular working conditions.

Q: Are your air conditioning units pre charged with refrigerant?

A: Yes. All our parking air conditioners come pre charged with eco friendly R134a refrigerant and are fully factory tested. No extra refrigerant charging is needed before first time use.

Q: What cooling performance can I expect from your parking air conditioners?

A: Cooling output varies among different series. Our parking AC units work well for standard size vehicle cabins. Under proper conditions, they can bring noticeable cabin temperature drop within a short period. Please refer to corresponding product specifications for exact BTU and wattage data.

Q: Can this air conditioner work with the vehicle engine turned off?

A: Yes. These are electric driven parking air conditioners made for engine off operation. They help cut fuel consumption and reduce engine wear during parking rest periods.

Q: What is your warranty policy, and are spare parts available?

A: We provide a 12 month warranty for main units. A full range of spare parts including compressors, fans and control boards can be supplied to support long term after sales maintenance.

Q: How loud will the air conditioner be during operation?

A: Noise level differs across product lines. Under normal operating conditions, most of our units run at ≤45dB, delivering quiet performance suitable for overnight rest inside the cabin.

Q: Can I complete the installation by myself?

A: Our parking air conditioners are engineered for user friendly installation. Basic hand tools are sufficient for assembly. We provide step by step installation videos and technical support. Many end users finish self installation within 2-3 hours.

Q: Can I start using the unit right after installation finishes?

A: Absolutely. Each unit is pre charged with refrigerant and strictly inspected before shipment. Once installation and power connection are completed, the system is ready for operation without additional setup.

Q: Do you offer OEM and custom order services?

A: OEM and ODM services are available. Options include custom branding, packaging, voltage adjustment, color and structural modifications, subject to minimum order quantity. Feel free to reach out to our sales team for further information.

Q: What is your typical production lead time?

A: Lead time varies based on order volume and stock status. For in stock items the shortest lead time can be 3 working days. The average production cycle is around 15 working days after order confirmation.

Q: Which shipping and trade terms do you support?

A: Applicable trade terms vary according to destination markets and order requirements. Please contact our sales team via email to discuss detailed shipping solutions for your project.
