2. Is this unit a liquid-nitrogen system or a mechanical refrigeration system?
The product name references liquid nitrogen, but the provided specifications list refrigerant R-404A, which indicates a mechanical refrigeration configuration. Please confirm with the supplier which configuration (LN2 or R-404A mechanical) you are purchasing, since installation, operation and safety requirements differ.
3. What temperature range can this blast freezer achieve?
The unit supports temperature control in the ranges -80°C to 0°C and -40°C to 0°C, allowing very low-temperature freezing for different product needs.
4. What are the electrical and power requirements?
The specification lists 220V voltage and a power rating of 1.7 kW. Verify local electrical compatibility and whether a dedicated circuit or special wiring is required for installation.
5. What are the unit dimensions and weight?
External dimensions are 880 × 740 × 1320 mm (L × W × H) and the unit weight is approximately 200 kg. Plan for sufficient floor loading capacity and space for service access.
6. What kinds of products is this blast freezer best suited for?
It is suitable for freezing fish and seafood, various cuts of meat, prepared foods, fruits and vegetables. As a plate freezer, it works especially well for flat or packaged items that can be pressed between freezing plates.
7. How quickly will it freeze my product?
Freezing time depends on product type, thickness, initial temperature, packaging and load size. Thin, single-layer products freeze much faster than large or dense blocks. For specific throughput and cycle-time estimates, provide sample product details to the supplier.
8. How easy is the unit to operate?
The machine is described as easy to operate and uses a PLC (programmable logic controller) for temperature control and automation. Basic operator training is recommended to ensure safe and efficient use.
9. How do I clean and maintain the blast freezer?
The interior is stainless steel 304 for hygienic cleaning.

Any refrigerant or compressor service should be performed by qualified technicians.
10. What safety precautions should I follow?
Follow general cold-guard and food-safety practices: wear appropriate PPE to prevent cold burns, ensure adequate ventilation (especially if using LN2 to avoid oxygen depletion), avoid confined-space exposure to cryogens, and train staff on emergency procedures. Confirm the unit type (LN2 vs mechanical) to apply correct safety measures.
11. What is the construction material and why does it matter?
The unit is made from stainless steel 304, which is corrosion-resistant, easy to clean and suitable for food-industry hygiene standards.
