Pegasus model is also a BMP test to evaluate the potential biogas volume. This model counts with 3 reactors with a bigger volume than the Nautilus model (5l).
This equipment is also easy sample handling and counts with robust stainless steel mixers. The material of the digester or tank reactor is 316 Stainless steel, but also with this model it is possible to store the digestate in a second tank attached to the reactors. The high reactor volume (3 litre) allows larger sample and inoculum volumes to be processed.
Pegasus model also allows the access to reactors via air-tight port during the tests for pH monitoring, nutrient supplementation, or sampling. It can have extra ports to flush the reactors with biogas/nitrogen at the start of the test.
Also, its stainless steel paddles guarantee thorough mixing even for high solid substrates.
