Unbroken. From load to delivery.
Cold chain is the discipline everything else depends on — there is no “mostly cold”: the chain holds or it fails, and failure shows up as spoiled product, rejected loads and, in healthcare, real harm. Wyvern runs cold chain as a controlled, monitored, documented system from loading to delivery — not a refrigerated truck and a hope. Our Afrit reefer fleet runs +25°C down to -25°C. Select a sector to see what we move cold.
Vaccines, blood and blood products, ARVs, biologics, lab samples and controlled medicines — moved under validated, qualified cold chain.
Fresh flowers, vegetables, citrus, avocados and berries — held in band to clear the market and meet export grade.
Fresh and frozen meat, poultry, fish, dairy, processed and ready foods — across the chilled and frozen bands.
Chilled juices, dairy drinks and temperature-sensitive beverage lines — kept in band from plant to shelf.
Chocolate, confectionery and any product with a tight thermal window — held in controlled cool to avoid bloom, melt or freeze.
Load & set
- Pre-cool — reefer brought to set-point a minimum of 2 hours before loading; box temperature verified before product enters
- Load fast, load right — minimised door-open time; product stacked for airflow, never blocking the evaporator or floor channels
- Set & lock — temperature band set and locked to the consignment’s requirement; the driver cannot override
- Continuous logging — IoT logger records temperature throughout, time-stamped and downloadable as a complete record per load
Monitor & hand over
- Live monitoring — readings monitored remotely; alerts on any drift toward the threshold so we act before a breach, not after
- Excursion protocol — on a breach, an automatic excursion report is generated and the consignee notified; contingency (backup unit, re-icing, re-routing) actioned immediately
- Cold handover — at delivery, temperature verified and logged at the door; signed/digital POD with the temperature record attached
Compliance & accreditation
- WHO GDP — Good Distribution Practice for pharmaceuticals: validated, qualified cold chain with documented control end to end
- HACCP — food-safety discipline for all perishable food and produce
- MCAZ — controlled-substance handling for regulated medicines moving cold
- Documented record — every cold load delivers with a downloadable temperature log; nothing is “trust us”, everything is evidenced
- Altitude derating — output adjusted for high-altitude destinations (JHB, Lusaka, Lubumbashi)
Why it fails elsewhere — and how we prevent it
- No pre-cool → product into a warm box. We pre-cool 2 hours, verified.
- Long door-open at loading → temperature lost before departure. We load fast with disciplined door management.
- No monitoring → breach found only at delivery. We monitor live and alert on drift.
- No record → disputes and rejected loads. We deliver a downloadable log every time.
- Breakdown with no plan → the whole load spoils. We run backup units, contingency routing and a clear escalation protocol.
