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.

  • 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.

  • 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 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 (Ammonia)

  • 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

  • Refrigeration Assembly

  • Natural refrigerant — GWP = 1

  • Compact pipe sizes, smaller charge

  • High heat transfer at low temperatures

  • Cascade with NH₃ for maximum efficiency

  • PU Panel Foaming

  • 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

    From spiral to fluidized bed, from poultry to seafood. Understand which freezing technology fits your product, capacity, and facility. Backed by 5,000+ installations across 80 countries.

    • Design–build
    • 200-person crew
    • Single warranty
    • Complete handover
