The Fröling T4 is the newest boiler to our lineup. The T4 is a commercial or institutional ASME-rated boiler that will burn both wood pellets or dry wood chips.
The Proctor Elementary School is approximately a 60,000 sq. ft. building that originally had a coal-fired steam system. It was converted to an oil-fired hot water system 30-40 years ago. The old oil-fired boiler was replaced with a modern new boiler and the new primary boiler is our Fröling T4 150. It is connected to an internal 20-ton pellet storeroom with easy fill access in the front of the building. The system was installed by Froling Energy 603-924-1001.
