I am selling this natural gas-fired Ajax Boiler HRNG-25 low-pressure steam boiler, featuring an inclined water tube design with 2-inch O.D. straight tubes and removable head plates for maintenance. It has a maximum BTU/hour input of 1,050,000 and a minimum BTU/hour input of 866,250, with a maximum allowable working pressure of 15 PSIG. The boiler is constructed with an 18 gauge-galvanized steel casing and includes a combustion chamber with castable refractory and rockwool insulation. It operates on 120 VAC / 60 Hz power with CSD-1 compliant controls. This was recently removed from a brewery that shut down.
