In 2015 I found CSR Edmonds in Australia while looking for whole house fan parts there. I met Allan Ramsay, Export Sales Manager, who was looking for a new distributor in America for their EcoPower series of hybrid rooftop ventilators. When he learned of my ventilation knowledge he assigned me to be his distributor. His EP900 was designed into the Molecular Engineering building at the University of Washington. That was a famous case study of the first large installation of a hybrid rooftop ventilator in America.
But the design had a performance deficiency. They motorized the turbine top. That limited the air flow performance in any usable static pressure. In 2016 I improved the design. It is now for sale here – http://inviscoindustrial.com/
