EXTRCOOL Inverter Cold Room, Three Layers of Design for Quiet Operation
AI Inverter, Sandwich Cotton and Inner Rotor Fan: Three Layers That Bring Operating Noise Down to 38-66 dB(A)
EXTRCOOL Inverter Cold Room delivers quiet operation through three layers: the AI inverter drive keeps the compressor running at set temperature instead of stopping it, removing the start-stop roar at its source; a double-sided felt sandwich sound-absorbing cotton gives more than five times the sound absorption of ordinary material; and an inner rotor fan with spiral airflow produces less wind noise than an outer rotor design. Overall operating noise stays between 38 and 66 dB(A). The core figures, 50% energy saving, ±0.5°C temperature control and 2 minute 30 second hot-gas defrost, come from the parent company's CNAS-accredited laboratory. EXTRCOOL provides variable-frequency cold storage solutions.
