History
1978 - Bruce Wiesemann founded Wiesemann Engineering as a manufacturer of precision sheet metal and close tolerance machined components. Repair of worn and failed wastewater treatment equipment led to the design of new screening equipment and resulted in a number of patents still used in the water and wastewater industry today.
1993 - After several years of rapid growth Wiesemann was sold. Patented improvements and new products were developed and launched with the re-emergence of the company in 1998.
2001 - With the retirement of Bruce Wiesemann, the company closed and Hydro-Dyne Engineering begins under the direction of Jay Conroy and several other former Wiesemann employees. Unique to the industry, manufacturing remains in-house with complete design and fabrication of all licensed equipment taking place at the original facility.
2003 - Hydro-Dyne discontinues licensing and acquires all original patents and trademarks. Entire screening product line is later acquired from Wheelabrator/US Filter/Siemens, providing the additional experience and records of hundreds of unique screening applications for the continued development of new equipment.
2007 - Operations are expanded with the purchase of the current office and manufacturing facility in Oldsmar, FL (Tampa Bay). The 20,000 sq. ft. facility is solely dedicated to the design, production, and testing of screening equipment.
Today - Hydro-Dyne Engineering continues to introduce exceptional quality screening equipment and service to municipal and industrial water and wastewater markets. Time proven equipment and newly patented designs are constantly being manufactured as we continue to add to our list of satisfied customers throughout the world.
Tomorrow - We will always be more than a screen supplier. We are inventors, engineers, and manufacturers of stainless steel screens, washing compactors, and conveyors. The highest quality equipment and service will be provided through our mission to retain complete control over our product line. All of our equipment will continue to be designed tested and manufactured at our facility by the highest caliber employees. We are your water and wastewater screening experts.
