Features
01
High-Efficiency Condenser Design
Features windward installation with large windward area. Inlet vents on both sides of the condenser top cover further reduce air resistance and enhance heat transfer efficiency. Fan layout optimized via CFD simulation leverages vehicle driving airflow to maximize operational energy efficiency.
02
Lightweight Structure
Adopts bottomless windward condenser design, with overall length within 2.5 meters. Compact layout ensures minimized weight and volume for space-efficient vehicle integration.
03
Eco-Friendly Bottom Shell Material
SZGZ (narrow-body) models use LFT (Long Fiber Reinforced Thermoplastics) + aluminum alloy for the bottom shell, offering higher specific stiffness/strength, superior impact resistance, improved creep resistance, and dimensional stability compared to composite materials. Total weight reduced by ~15%.
04
Tool-Free Installation & Maintenance
SZG wide-body series condensers feature hinged top cover design, eliminating the need for full cover removal during installation and saving 50% setup time. Condenser fans install from top-to-bottom, allowing maintenance without opening the cover. Evaporator fan access requires only partial side cover removal for simplified after-sales service.
05
Enhanced Safety Design
Eliminates secondary bonding on roof-mounted evaporator side beams. Innovate integrated bottom shell bending structure for air duct reduces overall weight while preventing water leakage during rain.
06
Versatile Application Range
SZG full series suitable for domestic buses (6-8.4m) and tourist vehicles (5-8.9m). SZGZ narrow-body models are 180mm narrower in total width and 120mm closer in air outlet spacing than wide-body versions, compatible with smaller vehicle platforms.
