​QSBRI Inc. specializes in commercializing technology in the energy sector with a strong focus on heating and solar heating applications.  
Passive Back Flow technology prevents fouling and scale build up in heat exchangers.  Allowing for the use of compact plate heat exchangers in applications and regions previously inaccessible due to hard water. 
Working with Dr. Stephen Harrison, director of the Solar Calorimetric Laboratory at Queen’s University, QSBRI works to develop new Intellectual Property and seeks licensing partners worldwide.

Featured Technologies

QSBRI is currently commercializing two innovative technologies: Passive Back Flow (PBF) and Integral Stagnation Control (ISC).  These two technologies are the result of years of research and development by Dr. Stephen Harrison and have a decade of tested, recorded experience.  Both have numerous applications in the global solar and HVAC industries and QSBRI is currently working with partners to develop these technologies into commercial successes .

News in Brief

​QSBRI is heading back to Chicago for AHR this January 21-24 to check out the latest and greatest in HVAC technology. We will be showcasing our new PBF valve design and video as well as meeting with manufacturers of desiccant AC units. We look forward to seeing you there.

QSBRI is pleased to announce a 2 year collaboration project With KACST

November 20th 2017, QSBRI is very pleased to announce the start of a two year collaboration project with KACST (King Abdulaziz City for Science and Technology). The project focus is the development, construction and testing of a solar driven solid desiccant air conditioning system. For more information please contact QSBRI. 

QSBRI meets with Guangdong FiveStar Solar Energy Company

In July of 2017 representatives from QSBRI traveled to Guangdong, China to meet with FiveStar Solar to discuss how QSBRI technologies can help FiveStar improve efficiency, lower costs and grow their market share. Testing of the PBF technology is underway in heat pump applications with promising results to come. A follow up trip is planned for the first quarter of 2018.
