Anaerobic Digester
Unique features
This patented system combines de-gritting with the well established low energy technique of Sequential Unconfined Gas Mixing.
Foam Alleviation
Our anaerobic digesters are designed to reduce the potential for foaming problems.

Long life insulated fibreglass roof
Fibreglass roofs provide a high degree of thermal insulation and have stood the test of time. These have been in use on digesters for in excess of 20 years. Fre Energy have not found a material roof that approaches this lifetime, or provides the same level of thermal insulation. The gas above a digester is wet, and if that moisture condenses on a cold roof heat will be lost .
