Founded in 1960 as a small infrared-heater manufacturer, Nanuet-based Casso-Solar Technologies now designs custom, turnkey infrared process-heating equipment for industrial manufacturers across North America. Its in-house laboratory helps engineers match wavelength and heat intensity to each customer’s process, with glass processing remaining a specialty developed over more than 50 years. The company supports its American-made systems from design and installation through lifetime maintenance, upgrades, and replacement heaters.
