Converting biogas into valuable green energy has been a cornerstone of GTI's business for over 30 years.

GTI's gas collection covers  reliably capture biogas produced by anaerobic treatment of waste so that it can be used as a renewable energy source. To complete the system, GTI offers biogas control systems  to take the biogas from the cover to energy recovery equipment.

We also offer innovative gasholders  to safely store and regulate biogas from anaerobic digestion.

Excessive algae growth can throw even the best water treatment processes out of balance. Algae can clog intake screens, fluctuate pH levels, increase chlorine demand, and negatively affect the taste and smell of water. Temperature is better controlled and maintenance associated with algae cleaning is simplified. The results? Better water treatment and lower operating costs.

Several cover styles can be used, depending on the application.

The trained staff can entirely customize your solution based on heat retention requirements. We perform heat loss calculations to determine the optimum insulation thickness of all our cover solutions.
Thermal protection is usually a complement to other cover functions such as biogas collection.
