Every SongXin HVAC product undergoes exhaustive testing to confirm it meets or exceeds industry standards. Our full-range protocols cover main equipment and terminal units, ensuring comprehensive validation.
Cooling/heating capacity and efficiency verified to AHRI, EN, and GB/T standards, with airflow testing to verify balanced ventilation.
100% refrigerant and water circuits pressurized to 1.6 MPa+ — leak-free guaranteed.
Conducted in precision acoustic chambers and vibration simulation platforms, maintaining levels as low as 35–45 dB(A) for quiet operation.
Grounding, voltage stability, and protective functions are tested to IEC and CE standards.
Continuous run simulations under real-world loads validate up to 35,000 operating hours for motors and bearings.
24/7 reliable operation with minimal maintenance needs.
To prepare our products for the harshest environments, we conduct specialized ambient tests in dedicated labs, simulating global climates and industrial challenges.
Our units are validated across an operational range from -40°C to +55°C and in high-humidity settings, ensuring consistent performance wherever they are deployed — from Arctic logistics hubs to tropical industrial plants.
Marine-grade protection validated for coastal and chemical environments. Components withstand prolonged salt fog exposure, ensuring structural integrity in the most aggressive atmospheres.
Life-cycle tests verify resilience against dust, odors, vibration, and corrosion — simulating years of real-world operation in compressed test cycles.
ATEX/IECEx certified units are engineered and validated for hazardous environments — including oil & gas platforms, chemical processing plants, and mining operations — where ignition risk demands the highest safety standards.
Systems stay dependable in oil & gas, nuclear, transport hubs, and extreme climate zones — no matter what the environment demands.
