If your boiler is not equipped with an economizer, you’re losing energy through your stack. Superior’s economizer was developed to recover wasted energy and is easy to install and maintain. We provide an automated program to allow you to see the savings your application will realize. Superior offers models to cover commercial to industrial watertube boilers. Our software also calculates the heat recovery for condensing applications.

Repairs are fast, easy, and require no welding. Replacement tube elements are kept in stock to minimize downtime. You can even operate your unit with one tube out of service to maintain your energy savings while waiting for the best time to shut down to repair. Cleaning is easy too with full maintenance instructions in your operating manual.
