IQC HVAC Production Test Systems
Tailored to your requirements our automotive HVAC test system detects faults based on user-defined metrics — with statistically generated tolerance limits.
Based on more than 30 years of experience, the Signalysis HVAC Production Test System replaces 
subjective tests with advanced vibration, sound, motor current and actuator performance metrics. Combining traditional NVH laboratory modal analysis, sound quality, gear testing, and motor dynamics test methods this proven test system brings 100% inspection confidence to your manufacturing floor.
IQC AUTOMATION controls HVAC operation through a defined list of functional tests. This maximizes test cycle time and optimize test data integrity.
IQC MEASUREMENT SYSTEM acquires dynamic response data from a defined set of transducers, sampling rates, digital filters, and sample sizes.
IQC ANALYSIS ENGINE employs high-level post-processing in time and frequency domains to detect faults in drive motors, gear systems, and other mechanical or moving parts during HVAC operation.
