Founded in 1989 by Bob Cree and Rick von Kraus, Addex designs and supplies blown-film cooling equipment from its base in upstate New York. The company is known for patented innovations such as its Intensive Cooling technology, External Gauge Control air rings and Digital Internal Bubble Cooling systems, which can be integrated into existing OEM lines or retrofits. Addex continues to operate independently under its own name following its 2025 acquisition by Windmoeller & Hoelscher.
