​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 will be attending and showcasing at this year's Ontario Centres of Excellence, Discovery conference being held at the metro Toronto Convention Centre, May, 9-10th.  Click below to visit the web page or contact us directly for more information and to set up a meeting.  Look forward to seeing you there. 

​QSBRI returns from successful AHR 2016 

QSBRI attended another successful AHR show in Orlando, FL in January.  Meeting with licensing partners and distributors QSBRI made significant inroads for the sale of PBF technology.  With the launch of the second generation PBF valve had our partners and interested parties keen to meet and see what new innovative technological advancements we have come up with.  
Contact us for more details.  Looking forward to seeing everyone again next year in Las Vegas. 

QSBRI showcased in Perspective Kingston Nov, 25, 2015

QSBRI is being showcased in this year's Perspective Kingston which is due out November 25th 2015.  This article will help promote QSBRI to the larger Canadian market and share some of the recent success.  Perspective Kingston will be available in the Globe and Mail November 3rd as well as at KEDCO offices, Kingston City Hall and Kingston Tourism offices.  Article available below, we are on page 6 

UPDATE: ISC valve exceeds 35,000 cycles  

Test on the ISC valve has exceeded 35,000 cycles with no alterations or modifications made to the valve.  The valve test rig timed out after more than 35,000 cycles due to the heating source failing.  The valve was removed and examined for stress points and wear damage.  Few signs of either were discovered and new bias springs and a new SMA spring were installed to test the valves ability to use smaller bias springs and a lower temperature SMA spring.
