"The folks at Pacific Environmental Technologies were instrumental in the design and construction of 3 clean rooms at our facility. (Approximately 25,000 Sq. Ft.) They also designed and installed a humidity control system that allowed the injection of controlled humidity during lower-than-normal Southern California dry spells. The PETI team provided excellent service during the design and building of these various project phases. Their continued maintenance support, documentation and contributory recommendations have been conducive to the uninterrupted manufacturing operations at our site. It was a pleasure to work with Jon and his team and I highly recommend and consider them as a primary source for design/build of all controlled environment projects."
