1. Reinforced Iron Shell Evaporator & Customizable Working System
Centered on a professional heavy-duty evaporator system, this unit adopts a robust iron shell outer structure, uniquely optimized for the harsh working conditions of engineering and heavy machinery. Unlike ordinary plastic and thin-shell evaporators prone to deformation and clogging, the thickened iron shell effectively resists construction dust, gravel debris, external collision and long-term vibration, completely solving common industry pain points including vent blockage, declining cooling efficiency and abnormal noise amplification during continuous equipment operation. Matched with a scientific 4-air-outlet working mode, the evaporator stably delivers cool air through four independent ventilation ducts penetrating into the cab. Users can freely arrange the indoor vents according to the cab layout, with conventional installation at four roof corners to achieve 360° uniform overall cooling, no dead angle in temperature reduction. Beyond structural advantages, the evaporator supports full personalized material customization: users can select high thermal conductivity aluminum evaporators for cost-effective and fast heat dissipation, or corrosion-resistant, durable copper evaporators for long-term service in humid, dusty and high-temperature harsh environments. The matched ventilation ducts also support multiple material custom options, perfectly adapting to different regional climates and working intensities.

2. Full Customizable Core Components
To match different vehicle models and working intensity, the product supports flexible core configuration selection. Customers can choose between scroll compressors for high-load stable operation and rotor compressors for cost-effective daily use, with optional brushed and brushless motors to balance service life and operational efficiency. Both evaporator and condenser support copper and aluminum material customization, adapting to diverse climate conditions and user maintenance needs worldwide.

3.Multi-Voltage Universal Compatibility
Covering 12V, 24V, and 48-72V wide voltage range, the air conditioner fits most heavy-duty machinery, engineering vehicles and special equipment with different power systems. The universal voltage design greatly improves product adaptability, meeting the matching needs of various global engineering vehicle equipment.

4. Flexible 4-Point Air Duct Cooling System
The evaporator is equipped with four air outlets, connected to four independent ventilation ducts to deliver cool air into the cab. Indoor vents can be freely arranged according to cab structure and actual needs, and are generally installed at the four corners of the roof to achieve full-coverage uniform cooling. Meanwhile, the supporting ventilation ducts are available in multiple material options, realizing personalized installation and improving overall equipment durability.

5. Compact Installation with Minimal Vehicle Damage
Designed for roof mounting with an integrated compact split structure, the unit occupies no redundant cab interior space. The optimized installation process avoids destructive modification to the original vehicle body, protecting the vehicle structure and appearance, and is suitable for long-term assembled use of heavy machinery equipment.

1.Compact Size with Super Customizable Cooling Performance
The mini-sized body achieves outstanding cooling output with matched low power consumption, supporting conventional and customized high cooling capacity. The 12V model features 300-800W rated power and 1600-2000W standard cooling capacity, with a maximum customizable cooling capacity of 3000W. The 24V version runs at 500-800W rated power with 2000-2600W standard cooling capacity, upgradable to 4000W maximum. The 48-72V unit delivers 300-800W rated power and 2000-3000W standard cooling capacity, with a customized peak cooling capacity of 4000W, fully meeting high-intensity cooling demands in high-temperature environments.

2.Ultra-Low Noise Comfortable Operation
Optimized internal structure and professional damping design effectively reduce operating noise. The running noise is far lower than that of traditional parking air conditioners on the market, eliminating noise disturbance during equipment operation and parking rest, and creating a quiet and comfortable working and resting environment for operators.

3. Strong Environmental Adaptability & Stable Operation
Thanks to the reinforced iron shell structure and customizable high-quality heat exchange components, the unit has excellent dust resistance, impact resistance and high-temperature resistance. It can operate continuously and stably in complex and harsh working scenarios such as construction sites, mining operations and field work, with no obvious cooling attenuation.

4.Diversified Scenario Universal Application
Benefiting from multi-voltage adaptation, flexible configuration matching and stable high-power cooling capability, this heavy-duty split parking air conditioner is compatible with all kinds of heavy machinery and engineering vehicles. It can adapt to multiple complex operating environments and working modes, realizing efficient cooling in different working and parking scenarios.
