Pfannenberg Inc., Lancaster, N.Y., is expanding its North American headquarters. Once completed this month, the expansion will add new engineering and office space, a laboratory and meeting rooms. Production space also will be redesigned to improve workflow between manufacturing, shipping and receiving, with added ramps and fork truck paths that will allow for better material handling.

The laboratory will include a new environmental test chamber to allow company engineers to increase product sizes and test them under extended temperature ranges. The new chamber will support UL certification.
