Houston Service Industries, Inc.

Houston Service Industries, Inc. ("HSI") was founded in 1974 to provide rotating equipment balancing and vibration analysis services to industrial and municipal customers in the Houston, Texas area. In the early 1980's the company became active in providing preventive maintenance programs to municipal wastewater plants. This activity soon evolved to include repairs of multistage centrifugal blowers. HSI has a line of ten models of multistage centrifugal blowers and is adding one to two new models per year. These machines' parts are interchangeable with popular Hoffman^® and Lamson^® models. HSI also provides aftermarket services for the existing Hoffman^® and Lamson^® centrifugal blowers.
