1. What is Reefer Container Shipping?
Refrigerated containers (Reefers) are specialized FCL units equipped with integral electric cooling units designed to maintain an exact setpoint temperature throughout deep-sea ocean voyages. ZT-AGENCY CHINA secures guaranteed reefer plug allocations aboard tier-1 shipping lines (Maersk, CMA CGM, MSC, Evergreen) connecting Chinese ports to Latin America, the Caribbean, Australia, and Africa.
Reefer Container Technical Specifications
| Container Type | Internal Dimensions (L x W x H) | Temp Operating Range | Usable Volume | Max Payload |

2. Quality Assurance: PTI & Cold Chain Protocols
A cold chain breach can ruin an entire multi-million dollar shipment. ZT-AGENCY CHINA enforces mandatory pre-loading quality gates:
- Pre-Trip Inspection (PTI): Carrier-certified mechanical, electrical, and refrigerant check prior to releasing empty reefer equipment to the shipper.
- Pre-Cooling Verification: Pre-cooling container interior to designated cargo temperature before loading begins.
- GenSet (Generator Set) Drayage: Providing clip-on or underslung diesel generators to keep the refrigeration unit powered during road trucking between factory and seaport.
- Cold Treatment (CT) Protocols: Continuous core pulp temperature monitoring required by Australian and Latin American biosecurity authorities.
