Safety comes from the top at Mollenberg-Betz.

Mollenberg-Betz was founded in 1910 by Henry J. Mollenberg and Jacob Betz as a machine shop serving nearby shipping, steel mills, and other industries. Early on, the founders were asked to design and install a refrigeration system for a dairy, and for several decades the company designed and manufactured custom refrigeration systems for a variety of industrial and commercial customers. During the 1960s, the company branched out into heating, air conditioning, ventilating and process piping and began a service department. In 1985, Mollenberg-Betz discontinued its machine shop and created a fabrication facility for piping assemblies, which are shipped to the location where they are installed.
