In Our Industry, Experience Matters

Our systems are designed to protect the environment and end-users, safeguarding them from leaks, fire and contamination. To prevent future complications, our experts are well-versed in the various regulations, statutes, and environmental codes that must be followed. As part of PEI’s 90 plus year history, quality installation and service have been the foundation of our success. In our line of business, there is no room for failure; excellence is all we have to offer. At PEI, we do our job so you can do yours.


Petroleum Equipment Inc. and our field staff specialize in the installation, maintenance and removal of aboveground and underground petro-chemical storage and dispensing systems. We work in a highly specialized field and take great pride in prioritizing the safety of both end-users and the environment. To that end, please see the following credentials related to our work. We are:

  • A Wisconsin Certified Tank Specialty Firm (cert. # 402149) with the following certifications:

Historically, it is difficult to find and hire employees who are knowledgeable about our specialized field and who also carry the numerous credentials outlined above. This is still true today, because there are no educational tracks available for those who want to learn about petro-chemical systems, our staff is trained in the field, in a hands-on manner. This training takes several years and is not replicable in a classroom or other educational environment. Our work showcases the value in this approach.
