Innovative Environmental Test Solutions for a Sustainable Future

Who We Are

Hanse Environmental designs and builds environmental test chambers and vibration systems in Allegan, Michigan — made in the USA for more than 35 years. Our HALT/HASS systems, temperature and humidity chambers, and patented multi-axis vibration equipment help the automotive, aerospace, electronics, and military sectors expose design weaknesses early — before they become recalls or warranty claims. Every system is backed by a three-year parts warranty and lifetime customer support, and our customers range from small businesses to Fortune 500 enterprises.

Our Story

John K. Hanse (1950–2021) was a pioneer of the environmental stress screening industry. He built this company step by step:

1989 — Founds Allegan Environmental, building custom chambers and Environmental Stress Screening equipment. First customers: Whirlpool and Ford Motor Company.

1992 — Co-founds Qualmark, manufacturing HALT/HASS systems.

1993 — Establishes Hanse Environmental, focused on HALT/HASS systems and custom-built chambers.

1999 — Merges with M.V.E. to operate as MVE/Hanse.

2000 — After Chart Industries acquires MVE, John's release from his non-compete allows operations as Hanse Environmental to start again — fully independent, as it remains today.

2009 — Ownership passes to his sons: Peter K. Hanse (CEO) and John H. Hanse (Sales Engineer), continuing Hanse as a family-owned American manufacturer.
