Nu-Calgon

What Nu-Calgon does

Nu-Calgon is a St. Louis, Missouri-based specialty chemicals distributor founded in 1991 that supplies the heating, ventilation, air conditioning, and refrigeration (HVAC-R) industry with chemical products and consumables. Its portfolio spans coil cleaners and sprayers, refrigerants (EcoPure), glycols, water filtration (Everpure), water treatment chemicals, gas leak detectors, ice machine maintenance products, insulation products, and indoor air quality systems including the iWave and NuShield bipolar ionization lines and the Scorpion UVC-LED air quality system. The company also markets leak sealants (EasySeal), refrigeration flush products (Rx11-flush), and startup/commissioning chemicals (NuStart). The products are largely physical and chemical formulations applied at the contractor or service-technician level for system maintenance, repair, and installation in commercial and residential HVAC-R settings.

The company operates a wholesale and contractor go-to-market model, selling through a network of HVAC-R wholesalers and contractors across North America, with international distribution handled through named regional partners covering Australia, New Zealand, the Caribbean, Central and South America, Mexico, Puerto Rico, Spain, Turkey, the United Kingdom, Israel, and additional markets. Revenue is generated through one-time product sales of branded chemicals and equipment rather than subscription or licensing. Nu-Calgon runs a free virtual training and certification program, Nu-Calgon University, targeted at wholesalers and contractors, and supports the channel with cross-reference tools, calculators, and a product registration infrastructure.

In 2025–2026 the company extended its scope into advanced-materials HVAC coatings through an exclusive North American distribution agreement with Graphene Manufacturing Group Ltd (GMG). Following EPA authorization in December 2025 for THERMAL-XR ENHANCE and a June 2026 EPA approval and first bulk shipment, Nu-Calgon began reselling the graphene-based coating under its CoolWorx sub-brand, adding an equipment-protection product category that did not previously exist in its US commercial offering.
