Napco Inc. is a manufacturer of wholesale appliance heating elements and related accessory parts for the HVAC parts market. I have been working with Napco for almost a decade and this is the third incarnation of their website. An online catalog of parts that they can update themselves using a browser-based interface.
The new website has an eye toward B2B design and functionality. Both a resource and a sales tool, it incorporates a mobile/tablet-friendly, responsive design as well.
