Prioritizing Energy Efficiency

We care about our planet and are conscious of our impact on it. This isn't just something we say. We are proud to be officially affiliated with both Energy Star and the United Nations Global Compact. With our addition of solar panels to our main manufacturing facility, we have been able to offset 80% of our annual energy consumption by capturing renewable solar energy.

Our energy-efficient practices address not only our operation and the production of environmental chambers and rooms, but also in the products themselves, including various components and the mechanisms used to cool the chambers, from lighting, fans, cooling technologies and more.
