What Corotec does

Corotec Corporation is a US-based manufacturer of corona, plasma, and ozone surface treatment equipment, founded in 1986 and headquartered in East Haven, Connecticut. The company designs and builds systems that modify the surface energy of materials — paper, plastics, metals, foams, and medical device components — to improve adhesion of inks, coatings, adhesives, and laminations. Its product portfolio spans narrow-web and wide-web corona treaters (up to 160 inches wide), blown film systems, sheet treating systems, Plasma-Jet 3D treatment systems (PJ-1 through PJ-4), LC Series ozone generators, NoZone catalytic ozone decomposers (100-7,500 CFM), and matched power supplies (LCT Series 1-10 kW, HFT-S Series 0.5-5 kW, S-Type smart power supplies), with proprietary technologies including the patented FlexiDyne electrode, Power Density Control System, and SmartStart microprocessor control.

The revenue model is hardware-centric with three streams: capital equipment sales (custom-quoted per application, typically multi-year capex purchases by industrial buyers), aftermarket parts (Dyne Pens, silicone sleeves, glass rolls), and a try-before-you-buy rental program that converts to purchase. Corotec sells primarily through direct enterprise field sales — regional sales managers in the US (Rick Dunaway) and Mexico (Odette De Botton) — supplemented by the Inductotherm Group's network of 40 companies for global distribution. Target verticals include converting and printing (primary), medical device manufacturing, automotive parts, foam products, and extrusion coating/lamination, with named enterprise customers including CCL Label, Atlantis Plastics, Optimum Plastics, and an undisclosed medical device manufacturer.

Corotec has been a wholly-owned subsidiary of Inductotherm Group since January 1, 2022, sharing an 80,000+ square foot facility with Thermatool Corporation in East Haven, CT. It is led by President & CEO Tom Ignatowski (30+ years of power-supply design experience, in role since 2018). The company holds registered trademarks for Plasma-Jet, Uni-Dyne, NoZone, Pulsed-Plasma, and SmartStart, a US patent on its FlexiDyne electrode design, and achieved CE certification for its Plasma-Jet system in November 2025 to enable European market entry.
