Freeze Time
Product thickness, water content, initial temperature, and target core temperature determine required dwell time. Thicker products need longer belt paths or slower belt speeds. Typical range: 8–120 minutes depending on product geometry.
Which Freezing Technology Fits Your Product?
Spiral or tunnel, poultry or seafood — selection guidance, capacity planning, and refrigerant trade-offs, drawn from 5,000+ installations in 80+ countries.
Capacity Planning
How Freezing Capacity Is Determined
Three factors interact to determine the right freezer size and configuration. Misjudging any one leads to under-performance or over-investment.
Throughput
Target kg/hr × freeze time = belt loading requirement. A 5,000 kg/hr line with 30-minute freeze time needs 2,500 kg of product on the belt at any moment. Belt width and tier count scale accordingly.
Heat Load
Product heat load (kW) = mass flow × specific heat × temperature drop. This determines evaporator surface area, fan power, and compressor capacity. Under-sizing the refrigeration system is the most common specification error.
Refrigerant Selection
NH₃, CO₂, or HFC (Freon) — The Trade-Offs
Refrigerant choice affects capital cost, operating cost, regulatory compliance, and site safety requirements. No single refrigerant is best for every application.
NH₃ (Amonyak)
Highest efficiency (COP) at industrial scale
Lowest operating cost per kW of cooling
Zero GWP — no F-gas regulation exposure
Self-alarming — detectable at 5 ppm
Soğutma Montajı
Natural refrigerant — GWP = 1
Compact pipe sizes, smaller charge
High heat transfer at low temperatures
Cascade with NH₃ for maximum efficiency
PU panel köpük
Simpler system architecture
Lower initial capital cost
Widely available service & components
Suitable for smaller installations
Integration Paths
Standalone Freezer or Complete Line?
Three integration models — from freezer-only supply to fully integrated turnkey production lines. Choose based on your in-house engineering capability and project complexity.
Freezer Only
We supply the freezer. Your team handles installation, refrigeration tie-in, and controls integration. Best for experienced operators with in-house engineering.
- Equipment supply
- FAT testing
- Your installation
Freezer + Refrigeration
Complete freezing system: freezer, refrigeration package, controls, and on-site commissioning by our engineers. You handle civil works and utilities.
- Equipment + refrigeration
- Our commissioning
- Your civil works
Turnkey Line
The complete line under one contract — freezing, refrigeration, conveying, and controls, designed and built by Square. Our 200-person crew handles civil, mechanical, and electrical installation through commissioning. One warranty. One handover.
- Design–build
- 200-person crew
- Single warranty
- Complete handover
