Key Features

Engineered for the Most Demanding Loads

The Model XL delivers the highest payload capacity in the standard Pro Line Heavy range, 800 kg and 100 kWh, while maintaining the full structural integrity, certification credentials, and operational features the range is built on.

Thermal Runaway Containment

Fully sealed bell jar design prevents fire propagation. Outer surface temperature stays below 100°C even during severe thermal events, protecting personnel and adjacent cargo.

Patented HF Gas Filtration

The Fibercon Altilium CP Blanket (FACB) neutralises hydrofluoric acid (HF) gas the most dangerous toxin released during lithium battery fires before it can escape the container.

No Filler Materials Required

Unlike traditional UN-certified containers, BUNCKER® requires no sand, vermiculite, or liquid fills. Faster loading, cleaner operations, and lower total cost of ownership.

All Transport Modes

Certified for road (ADR), sea (IMDG) and rail (RID). One container, one certification no mode switching, no recertification.

Stackable Design

Engineered corner posts allow safe stacking up to 1,240 kg. Optimise storage density and reduce warehouse footprint while maintaining structural integrity.

Service & Inspection Programme

All BUNCKER® units come with a certified service programme including regular inspection intervals, replacement parts availability, and documented maintenance records.
