Self-Recuperative BurnerThe TJSR is a direct-fired, self-recuperative burner based on Eclipse’s ThermJet burner technology. The TJSR design provides excellent heat recovery and eliminates the need for the hot-air ductwork required by external recuperators. The rugged construction ensures dependability and reliability. The TJSR is available in three sizes, with maximum capacities ranging from 200,000-600,000 BTU/hr (60-175 kW). TJSR burners, which can be fired on natural gas, propane and butane, do not require a pilot and can be started reliably anywhere within the ignition range.
