Description
Range and configurations
- The range covers semi-underground and above-ground bells with a consistent design language, useful for mixed islands or extending the service without new excavation.
- Internal containment follows the fraction and operator: bag, polyethylene tub or steel liner for source-separated, residual and dedicated streams, including organic collection.
- Where semi-underground installation is not practical, above-ground bag units remain available, aligned with the recessed campana design.
Capacity, footprint and emptying
- Volumes run from 800 L to 5,000 L with a compact external footprint (up to about 1,700 mm on the 5 m³ model), an advantage on space-limited islands.
- Emptying is available for single hook, twin hook and Kinshofer lift systems, in line with vehicles and procedures already in use.
Service control and urban integration
- On request we integrate access control and fill-level monitoring to plan rounds and manage island access.
- For urban integration the Traflux line (made in Belgium) adds a safety barrier ≥ 800 mm during emptying, an ergonomic internal lid and finishes in aluminium, composite or coloured covers, with configurable volumes above 3,000 L and Bunder Waste support on accessories and local service integration.
