Zilmet has updated how installers access technical support with the launch of Cal, an AI assistant integrated into its website.
The tool provides instant, 24/7 access to product information, datasheets and sizing guidance – a shift away from traditional methods such as printed sizing wheels and apps.
While installers can still contact Zilmet engineers directly for support, Cal is designed to improve speed and convenience by removing the need for searches or waiting times. It delivers immediate answers based on the company’s full technical knowledge base.
The system is continually improving, learning how installers phrase questions in different ways. Users are encouraged to interact with Cal in their own terms, helping refine its accuracy and usability over time.
Stuart Gizzi, MD of Zilmet, says: “The information has always been there – on the website, in the datasheets, on the end of the phone. Cal doesn’t change what we know, it changes how quickly and easily installers can get to it. We’d encourage installers to give it a proper workout.”
