In 1989, the UltimateAir parent company, Stirling Technology, developed the patented rotary core heat exchanger based on development of today's Stirling engine pumps and generators. The goal was to develop a whole-house ventilation system requiring little energy to operate. It was here in Athens, Ohio where the UltimateAir RecoupAerator® was born. UltimateAir is now the exclusive manufacturer for this patented technology in North America and Europe.

UltimateAir’s parent company, began as a renewable energy research company based on years of expertise with Stirling engines. Stirling engines run on any external heat source like solar or bio mass. Invented in the late 1800s by a Scottish minister named Robert Stirling. Stirling Technology systems are capable of powering homes in the US & small villages in underdeveloped countries. Today, Stirling Tech continues to develop patented systems and license its technology throughout the world.
