Harv opened HPI in 1962 after a successful career with a major oil and gas company. In New Mexico, he realized the market lacked top-notch and dependable natural gas compression equipment. HPI had operated other manufacturers’ compressors for years, which meant it knew what makes a solid compressor package (and lousy packages as well). The company used its market knowledge and willingness to step out of the box to fabricate well-built and dependable compressors. Its designs quickly gained popularity and HPI soon became the go-to firm in many states for compressors that today continue to withstand the test of time.
