Who We Are


E-Flux strives to solve environmental problems with unique and simple solutions. Our team works closely with clients to identify their needs and to develop innovative technology and services.

Customer Relationships

From its beginning, E-Flux was designed to be an industry-focused company that understands the unique needs of its applied research customers and provides them with cost-effective, solution-oriented services. As the founder of E-Flux, Dr. Julio Zimbron has consistently sought feedback from clients to continually improve product quality, ensure prompt and efficient ordering and delivering, and foster positive relationships with clients.

Company History

Since January 2013, E-Flux has been a client company of Colorado State University (CSU) Ventures, an organization dedicated to the transfer and commercialization of innovative technologies discovered at CSU. E-Flux's offices and labs are housed at CSU's Research and Innovation Center.

E-Flux Fossil Fuel traps were invented by a team of researchers at the Center for Contaminant Hydrology at CSU, including research scientist Dr. Julio Zimbron and Dr. Tom Sale, a professor in CSU's Department of Civil and Environmental Engineering.

Developed with funding from industry sponsors including Chevron and Suncor Energy, the E-Flux Fossil Fuel traps were conceived as a cost-effective solution to the complex problem of accurately measuring petroleum biodegredation rates in soil at petroleum spill sites.

To meet the needs of this growing customer base, the technology was migrated from CSU to E-Flux, a private company founded by Dr. Zimbron to lease the carbon traps to customers and provide them with customized analysis of the data collected in the traps. This proprietary technology has been implemented at petroleum-impacted field sites around the world, including active and closed refineries, rail yards, gasoline stations, and industrial facilities.

In March of 2017, E-Flux launched its second product offering, the Map Traps. Utilizing similar but less sensitive testing capabilities, these traps are used to delineate petroleum based contaminated areas by providing a binary (yes / no) indication of the presence of petroleum.

A third product, BioTherm, followed shortly thereafter in May of 2017 which is a web-based thermal modeling tool used to enhance the conceptual site model. The knowledge gained from this tool allows site teams to maximize the benefit and timing of their treatment and testing efforts.

E-Flux Fossil Fuel Traps are the ideal solution for:

  • Identification of zones where LNAPL natural attenuation is active
  • Long-term monitoring
  • Remote or limited access sites
  • Cost-controlled budgets
  • Minimizing environmental footprint of monitoring activities
  • Documenting natural source zone depletion (NSZD)
