A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The standard operating temperature range is -40°C to -35°C. However, note that operating below -40°C may cause excessive energy consumption. Always verify the specific range for your model with the manufacturer.
The inner lining is stainless steel grade 304 (ASTM A240), the insulation is polyurethane foam or PIR (polyisocyanurate) with a thickness of 150–200 mm, and the outer casing is also stainless steel grade 304. These materials provide food-grade hygiene and thermal efficiency.
The tunnel requires a three-phase electrical supply of 380–480 V AC, 50/60 Hz, per IEC 60038. Power consumption, including fans, controls, and defrost, ranges from 15 to 45 kW. Confirm the exact requirements with the manufacturer.
The tunnel is designed to maintain a temperature uniformity of ±3°C, ensuring consistent freezing quality. This is achieved through the insulation design and the controlled flow of cryogenic gases. For specific performance, consult the manufacturer.
