Global Thermoelectric is best known for its experience with thermoelectric generators or TEGs. In fact, this technology set the foundation for our business over 30 years ago. Global has TEGs in over 50 countries around the world. Global is the world's largest manufacturer of TEGs. Its systems are incredibly tough, due in part to the fact they have no moving parts. This makes them ideal for long-term unattended operation in remote locations that may be exposed to harsh conditions or where site visits are difficult. Features of Global TEGs: Operate on natural gas, propane or butane Hermetically sealed power unit with 20-year design life Burner system constructed from high-temperature alloys Stainless steel cabinets Automatic spark ignition Automatic safety shutoff
