When you choose Horizontal Rentals Inc, you tap a wellspring of expertise and innovation. HRI products represent the culmination of two generations of work in the drilling business by Glennwood Warncke and his son, Roger. We are proud to say that theory and supposition have played no part in the invention of such highly efficient products, our oil skimming systems, our drilling fluids cleaning system or our mud/gas separators, but hard work and personal experience have.
