Trans-Critical CO2 Heat Pumps

CO2 Heat Pump Testing

QSBRI is pleased to announce that it has completed accelerated fouling comparison testing of a brazed plate gas cooler installed with Passive Back Flow technology and a spiral gas cooler.  Results indicate that the plate gas cooler with PBF maintains its flow throughout the testing while the spiral gas cooler flow decreased and ultimately stopped, resulting in the failure of the system. Complete results will be posted shortly. Please check back regularly and contact us for more details.
