In 1964, Howell Laboratories, Inc. (HLI) incorporated and began designing and manufacturing equipment for the US Navy and US Coast Guard. In 1980 HLI purchased Shively Labs (www.shively.com) and consolidated operations at our current location. Shively Labs is a wholly-owned subsidiary of HLI which designs and manufactures the world’s leading technology in FM broadcasting equipment.

HLI became an employee-owned company in 1995. We believe this employee ownership increases our competitiveness by increasing productivity through greater participation in the workplace, and that it maximizes human potential by enhancing the self-worth, dignity, and well-being of our team.

HLI developed and marketed many products over the years, beginning with compressed air system components such as desiccant dehydrators, air control panels, and high- and low-pressure frost point indicators. In the early 1970’s, HLI developed the first on-line gloss meter for the paper manufacturing industry. In the mid-1990’s HLI established a business relationship with BEKO Technologies and added membrane air dehydration technology to the product offerings for air systems. At the same time HLI began development of potable water treatment systems using Bromine. In the year 2000, HLI entered into a licensing arrangement with MIOX Corporation, and developed Electrolytic Disinfectant Generators to treat shipboard potable water systems. In addition, another agreement with Azienda Chimica Genovese (ACG) yielded development of seawater chlorine generators, also referred to as anti-fouling systems, used to treat seawater piping and heat exchangers to eliminate micro- and macro-fouling to keep them running efficiently.

HLI has a long history of designing custom systems suitable for the harsh marine environment. It is this ability to adapt current products or apply new technologies to solve customer’s problems that has driven our continued success for nearly five decades. HLI is proud to serve the US Navy and US Coast Guard; we now are taking these decades of experience to the commercial marine industry.
