Our History

We can help you operate your pollution abatement equipment in ways that will save you money while improving your operational efficiency. RHZ was founded in 2006 by Russ Friend, who previously spent seven years working as a site supervisor and field engineer for a well-known firm in the industry, and Holly Oyster, an experienced HazMat material handling project manager and logistics expert. We specialize in assisting industry in the intelligent control and optimization of widely-used pollution abatement systems. Russ and Holly have built a company with a well-founded reputation for an extraordinary ability to coax higher efficiencies and shorter down-times out of well-used equipment. Personally, Russ is an experienced programmer of VFDs, burners, and analog controls and has a tremendous record of providing enhanced solutions to customers, utilizing standard equipment.
