Custom Cold Rolled Steel Heat Pump Enclosure

Today more than ever, efficient use of energy is very important. The heat pump enclousre shown here was designed to pre-heat hot water by extracting heat from ambient air and thereby reducing the amount of energy required to bring it up to temperature typically required for residential use. Our customer had a basic design for this enclosure. In reviewing for fabrication the Bull Metal engineering and production team brought forward some design changes and tweaks to so some details that both improved the fit and function of the finished unit and made for a more cost efficient production of the enclosure. Fabricated from 18, 20, and 22 gage cold rolled steel, this three part enclosure measured 18.00” in length, 16.00” in width, and 15.00” in height. The steel components that make up the unit were initially cut on our shear, and then moved to one of our turret presses to be precision punched creating consistently accurate flat blanks. Integrity of the blanks was verified by both dimensional inspection and through visual comparison with approved template. Parts were then formed on our one of our brake presses.

Metal Fabrication of Cold Rolled Steel Heat Pump Enclosures for the Plumbing & Heating Industry

Threaded inserts (Pem studs, nuts, and stand-offs) were pressed into components parts, and then the formed components were welded together by spot welding or TIG welding. . The completed units were powder coated; the cover finished with our very attractive # 110 blue gloss powder and the chassis finished with our very durable # 19 black texture powder. This complex assembly exemplifies our ability to produce multi-component custom fabricated enclosures for the plumbing and heating industry.
