V3 - The most exciting innovation in gas fired unit heaters for many years. Reznor’s extensive research and development has resulted in a technically advanced range of unit heaters that deliver the highest possible standards of energy efficiency and performance.
Incorporating a radical new heat exchanger and burner V3 is compact, lightweight and provides end users, consulting engineers and installation contractors with the ultimate unit heater solution.
 
Energy Saving
4-pass heat exchanger achieves over 92% thermal efficiency.
Reduced carbon dioxide and NOx emissions.
Eligible for 100% enhanced capital allowances.
Improved airflow and new louvre design give longer air throws and significantly reduces stratification within the building.
Aerodynamic heat exchanger profile enables up to 20% increase in airflow with a 30% reduction in electrical consumption.
   
Easy Installation and Maintenance
Up to 37% lighter than comparative models.
Balanced flue wall terminal provides both flue outlet and combustion air inlet thereby reducing installation time.
Balanced flue units eliminate the need for combustion air grilles in the wall.
Application Versatility
Both horizontal and vertical down flow
(combined heating/ destratification) units are available.
The smallest unit is only 310mm high - Making it ideal for mounting in confined areas e.g. underneath mezzanine floors.
 
     
   
V3 is suitable for a wide range of applications - industrial and commercial premises; retail; sports and leisure; warehouses, logistics and distribution centres.
Vertical downflow models are ideal for warehouse heating.
 
Enhanced Safety
Room sealed units draw combustion air from outside the building thereby preventing contaminants from entering the combustion zone.
 
Extended Operational Life
The titanium stabilised aluminised steel heat exchanger is particularly strong and durable providing additional temperature resistance. Its weld free construction ensures long life.
