The Cleaver Brooks CB model is a skid-mounted packaged boiler complete with the boiler, integral burner, and all required controls and safety equipment. This CB is a four-pass dry-back firetube boiler, constructed to ASME Section I code and utilizing 5 sq ft of surface area per boiler horsepower.

This boiler was purchased new from Cleaver Brooks by Powerhouse and placed into a custom design portable boiler room for sale. After many years of reliable service the boilers were purchased back by Powerhouse. 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.
