The Johnston PFTA Series is a skid-mounted packaged boiler complete with boiler, burner, and all required controls and safety equipment. This PFTA is a four-pass wet-back firetube boiler, constructed to ASME Section I code and utilizes 5 sq ft of surface area per boiler horsepower.
This boiler was purchased by Powerhouse from a customer who was replacing these boilers with new ones. This boiler has since been fully reconditioned and tested for a new customer. Our reconditioning process verifies that this boiler is 100% functional and ready for many more years of service which is why we offer a 1-yr warranty that matches or exceeds the original factory warranty.
