The company sells both reclaimed and new refrigerants and also buys used refrigerants for reclamation and sale. In addition, Hudson Technologies offers on-site decontamination services, as well as services designed to improve the efficiency of customers' refrigeration systems. Customers include commercial and industrial enterprises and government entities, along with refrigerant contractors, distributors, and wholesalers and makers of refrigeration equipment.
