Temperature Zones

Calibrated environments for diverse SKUs — from blast-freezing tunnels to CA rooms for long-term fruit storage.

-18°C to -25°C

Frozen Storage

Deep-freeze chambers for meat, seafood, and long-term storage where temperature stability and door discipline are critical.

  • High-density insulation and vapor barrier
  • Rapid doors and anti-frost strategies
  • Floor heating loops to prevent subfloor frost
0°C to +4°C

Chilled Storage

Fresh produce, dairy, and beverages benefit from tight temperature uniformity with gentle airflow and humidity control.

  • EC fans for uniform airflow
  • Smart dehumidification balance
  • Product-safe coil temperatures
0°C to +2°C

CA/MA Storage

Controlled/Modified Atmosphere rooms modulate O2/CO2 for apples, pears, and exotics to extend shelf life significantly.

  • Gas-tight envelope with scrubbers
  • Door interlocks and slow ramping
  • Continuous gas monitoring & logs
-30°C to -40°C

Blast Freezer

High-capacity blast tunnels to rapidly remove field heat and pass through the danger zone for quality retention.

  • High static evaporators and ducting
  • Staged defrost strategies
  • Throughput-optimized cart flow
+2°C to +8°C

Pre-Cooling

Hydrovac/forced-air pre-cool before storage reduces respiration rates and post-harvest losses.

  • Forced-air plenums and shrouds
  • Product-specific cooling curves
  • Data-logged core temperature

Infrastructure & Build

Food-grade envelope, engineered floors, rapid doors, and modern plant rooms — tuned for hygiene, durability, and safety.

Insulated Panels

  • PUF/PIR panels with camlocks, 60–200 mm thickness
  • Food-grade laminates, cleanable finishes
  • Detailed vapor barrier and joint sealing

Doors & Docking

  • Rapid roll-up and swing doors with heaters
  • Dock levelers, shelters, and bumpers
  • Air curtains for infiltration control

Flooring & Racking

  • Heated slab or glycol loops for frozen areas
  • Antiskid coatings with drainage slopes
  • Mobile/drive-in racking for high density

Refrigeration Plant

  • Ammonia/Freon with VFD compressors
  • Hot gas defrost, heat recovery
  • PLC/SCADA with remote access

Cold Chain Process

From dock to dispatch — staged controls and visibility reduce losses and protect product integrity end-to-end.

Step 1

Inbound & Pre-Check

Dock intake, visual checks, probe sampling, and ASN reconciliation to validate conditions and paperwork.

Step 2

Pre-Cool / Blast

Remove field heat or rapidly freeze to pass the danger zone quickly while tracking core temperatures.

Step 3

Putaway

Location assignment by temperature zone, rotation rules (FEFO/FIFO), and SKU compatibility.

Step 4

Monitoring

Continuous sensing of temp/humidity/door and real-time alerts with audit-friendly logs and graphs.

Step 5

Picking & Dispatch

Order consolidation with minimal door time; validation, labeling, and cold-chain handoff.
