T-REX TECHNOLOGY SYSTEMS
The T-Rex digesters are highly efficient large capacity systems with high gas production designed for Farms, Children's homes, Universities & institutions, Schools, Hotels and anywhere with a high-energy demand.
The systems are also designed as waste management devices for market places, municipal waste management etc.
T-Rex systems are modular making the plant easily scalable to meet the client requirements. The system is of longitudinal "True Cross Flow" methodology, or you could say a continuous batch-flow.
This meaning anything fed in the inlet end will be forced to flow the full length of the system (minimum retention period of 25-40 days) whereby getting fully digested, and having given off all the biogas potential by the time it overflows the exit as a rich organic fertilizer and pest repellent.
The T-Rex biogas plants runs on any bio-degradable material as feedstock and therefore does not limit the user to use of only cow dung.
All our plants are designed with the operator in mind – simple to understand and operate. Feed one end, a turn or two of the agitation wheel, and the system does the rest. Gas is piped directly to the point of use, and "Ready To Use" bio-fertiliser automatically overflows from the opposite end into a collection tank.

Flexi Technology was born out of over 20 years of research and development and in consideration of all aspects and inefficiencies associated with conventional constructed biogas technologies.

please note:
In a boarding institution (or a facility where people are served 3 meals per day per person), 1m3 of biogas will cook for approximately 5 people.
In a day institution (or a facility where people are served 1 meal per day per person), 1m3 of biogas will cook approximately 10 people.
The systems are modular and scalable to meet the energy demand.
