Overview

The Cleaver Brooks 4WG model is a skid-mounted packaged boiler complete with the boiler, burner, and all required controls and safety equipment. The 4WG is a four-pass wet-back firetube boiler, constructed to ASME Section I code and utilizing 5 sq ft of surface area per boiler horsepower. This particular unit is designed and built to operate with low emissions (30 ppm) while maintaining the high fuel to steam efficiency that Cleaver Brooks boilers are known for.

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.
