Who we are

ESPEC North America (ENA) is partner in environmental and accelerated reliability test chambers and solutions with a long history and deep expertise in making the world a better place through better quality, higher reliability products.


We continually aim to grow and evolve by building mutually responsive, innovative partnerships with our customers, vendors, and strategic allies, and creating opportunities for our team members.

Our cornerstone is to be the most reliable and accessible supplier of testing solutions.

How we got here

ESPEC North America was a true child of the eighties when we were established in 1983 as the North American, fully independent subsidiary of our parent company, ESPEC Corp, based in Kobe, Japan. ENA is headquartered in Hudsonville, Michigan where we design, manufacture, sell and support both our American-made models and some of our parent company’s Japanese environmental chambers in a 136,000 square foot plant whose Quality Management System is certified as being in conformity with ISO 9001:2015 by Intertek.

Almost 40 years of experience building test chambers in America goes into everything we create, from smaller standard equipment, to large custom chambers. Quality is designed into our processes, built into our equipment, and the lifeblood of our growth strategy. ENA’s merger with Qualmark in 2018 further corroborates this and expanded our product line, as well as our manufacturing, engineering, and support infrastructure. With a significant investment in a brand new, state of the art, LEEDTM certified building in Colorado, we are capable of even more dynamic and responsive service to our customers, especially along the West Coast. Our new Colorado facility boasts about 28,000 square feet with the potential to expand as we continue to grow; not to mention, a dedicated HALT/HASS lab with room for environmental testing services.

We have established a network of highly trained and qualified Independent Sales Representatives that are ready to help you navigate the chamber selection process, streamline purchasing, and engage our industry expert partners. Beyond Sales, ENA works hard to make expert Service techs ready and available to address start ups and customer needs when they arise. Our leading industry partners like Airgas, Air Liquide, Acme/Midwest Cryogenics, and others come together to further support and benefit our customers so you receive the best experience and offering in the marketplace.
