HVAC Radiator Pressure Pulse Test Bench | Heat Exchanger Impulse Fatigue Testing System

The Heat Exchanger Pressure Impulse Tester from HONGCE is a purpose-built durability testing system designed for air conditioning radiators, condensers, evaporators, and other refrigeration heat exchange components. By applying precisely controlled pressure pulses and temperature cycling to test samples, this equipment simulates the long-term mechanical stress that components experience in actual HVAC and refrigeration systems, enabling quantitative evaluation of fatigue life, seal reliability, and structural strength.

Our air conditioner radiator pressure pulsation test machine supports a peak pressure span from 100 kPa to 1000 kPa, with valley pressure adjustable from 0 kPa up to 90% of full scale. The ±0.5% FS pressure control accuracy delivers consistent, repeatable test conditions across every sample — the foundation of reliable fatigue life data.

Unlike competing units limited to 2–3 basic waveforms, our system supports sine wave, trapezoidal wave, triangular wave, sawtooth wave, step wave, linear wave, and fully user-defined waveforms. This flexibility lets you match test profiles to exact real-world operating cycles, whether simulating steady-state runtime or extreme transient pressure spikes.

Recreate the full spectrum of operating environments with medium temperature control from -40°C to 135°C and ambient temperature control from -40°C to 150°C. This wide thermal window covers both frigid cold climate conditions and high-heat equipment room scenarios, ensuring your components perform reliably in every target market.

Choose from 3–30 L/min or 6–80 L/min medium flow ranges, configurable to match the specific flow rates of your radiator and heat exchanger designs. The closed-loop circulation system maintains stable medium conditions throughout extended pulse test runs.

Equipped with a PLC control system and touchscreen HMI, the tester enables straightforward parameter setup, real-time test monitoring, and automatic data logging. Test cycles can be set freely per international standards or custom protocols, and the system automatically generates exportable test reports for quality documentation and certification submissions.

The system features layered safety mechanisms including over-pressure protection, over-temperature protection, leakage alarm, and emergency stop, ensuring operator safety and preventing equipment damage during long unattended test runs.

At the core of our pulse test bench is a high-precision closed-loop pressure control system, paired with advanced waveform generation algorithms and a precision thermal regulation unit. Key technical capabilities include:

• Closed-loop pressure feedback: Real-time pressure adjustment maintains pulse accuracy and stability across millions of cycles
• Dual-stage temperature control: Integrated refrigeration and heating systems sustain precise medium and ambient temperatures
• Automatic data acquisition: Continuous sampling of pressure, temperature, flow, and cycle count with no manual recording required
• Failure detection: The system identifies sample leakage or rupture and automatically stops testing, recording the exact cycle count at failure
