Four bands, each qualified and audited separately
A cold chain is only as good as the weakest handover in it. We qualify every zone independently — equipment, chamber, vehicle and packaging — and publish the tolerance we hold.
Frozen
Standard frozen grocery and food service. The volume zone: scheduled trunks, wave picking and mixed-pallet build.
Tolerance ±1.5 °CChilled
Fresh produce, dairy, protein and the pharmaceutical cold chain. Dual-probe logging and GDP handling on the medical lanes.
Tolerance ±0.8 °CControlled ambient
Room-temperature pharmaceuticals and heat-sensitive dry goods that still need a documented, bounded environment.
Tolerance ±2.0 °CService Lines
Twelve operating programmes, each with a published set point, control tolerance and audit trail. Pick the zone your cargo lives in.

Where cold chains actually break
Six handovers between the production line and the receiving bay. Select a stage to see the zone we hold, the realistic dwell time and the failure mode we design against.
Stage 01
Origin plant
Product handover
- Held at
- As produced
- Typical dwell
- 0.5 – 2 h
- Control
- Dock seal + acceptance probe
Failure modeWarm handover. Product frequently arrives above set point straight off the line, so we pre-chill the dock and refuse loads outside the acceptance window.
Programme covering this stage: Pre-Conditioning & Passive Shipper Build
Stage 02
Blast & cold store
Pull-down and buffer
- Held at
- −35 °C to −18 °C
- Typical dwell
- 6 – 72 h
- Control
- Core probing + airflow racking
Failure modePull-down rate. Core temperature lags surface temperature by hours, so racking is loaded for airflow rather than density and cores are probed before release.
Programme covering this stage: Blast Freezing & Tempering
Stage 03
Line-haul
Trunk movement
- Held at
- Set point ±1.5 °C
- Typical dwell
- 8 – 40 h
- Control
- Telemetry + N+1 swap unit
Failure modeMachinery failure and fuel. The longest unattended leg. Units run on telemetry with a fuel floor alarm and a swap tractor inside the corridor.
Programme covering this stage: Frozen Line-Haul Reefer
Stage 04
Cross-dock
Deconsolidation
- Held at
- Chamber matched
- Typical dwell
- 20 – 90 min
- Control
- Matched chamber + capped dwell
Failure modeDoor events. Every dock touch is a heat load, so transfers happen inside a temperature-matched chamber and the clock is capped by SOP.
Programme covering this stage: Cold Cross-Dock & Deconsolidation
Stage 05
Last mile
Route delivery
- Held at
- Passive or active
- Typical dwell
- 2 – 9 h
- Control
- Pre-conditioned shippers
Failure modeRepeated stops. Dozens of door openings per route. Loads travel in pre-conditioned passive shippers so the box, not the van, holds the temperature.
Programme covering this stage: Last-Mile Insulated Delivery
Stage 06
Receiving point
Proof of condition
- Held at
- Customer spec
- Typical dwell
- 5 – 20 min
- Control
- Logger read-out + signature
Failure modeUndocumented handover. Without a signed record the whole trace is worthless, so the logger is read out and countersigned at the point of delivery.
Programme covering this stage: Temperature Data & Compliance ReportingPassive hold simulator
How long does the load stay in spec once the machinery stops? Move the ambient temperature and the model recalculates effective hold time for each packaging grade we operate.

Operating footprint and lane times
Eight temperature-controlled nodes linked by scheduled reefer trunks. Select a node for its chamber mix and capacity. Locations shown are illustrative.
Compliance regimes we operate under
Cold chain is a documentation business as much as a refrigeration business. Every chamber, vehicle and shipper is qualified, and every deviation is investigated and closed out.
Good Distribution Practice for medicinal products, with qualified premises and validated routes.
Hazard analysis and critical control points across every food handling chamber.
Food safety management applied to warehousing, cross-dock and transport.
Quality management covering booking, execution and claims handling.
Third-party audited storage and distribution standard for retail supply.
Perishable cargo handling for airside and cross-border consignments.
