With the largest capacity of the THERMO-KING range of composters from Garantia, this unit can hold up to 900 litres of compost and due to its Thermolen® technology will give you fast composting results.

As a result of using Thermolen® technology within the plastic walls of the composter, your compost remains insulated throughout the year which increases the speed of the composting process; leaving you with high-quality compost in a fraction of the time compared to cheaper alternatives.

Your composter will arrive flat-packed and assembly could not be simpler with no tools required to erect it, allowing you to start using it straight away. Like other composters from Garantia's range, the unit is sustainably manufactured using only 100% recycled plastic for a tough and durable unit that will last for years to come, backed by the manufacturer's 3-year guarantee.
