Triangle Manufacturing Partners with Robur for High-Efficiency HVAC Solutions

Triangle is proud to partner with Robur to increase efficiency in the HVAC industry; helping both the environment and consumers.

Triangle Manufacturing is proud to partner with Robur, who offers one of the most advanced solutions in HVAC, using up to 40% of renewable energy. Robur, a German manufacturer of heat pump heating and cooling systems and Triangle, a Wisconsin-based manufacturer of motor mounting brackets have partnered together to create capable systems for Europe's stricter high-efficiency standards.

Environmentally friendly and highly efficient, Robur units are ideal for heating multi-family houses, industrial buildings and commercial facilities. Robur units permit a considerable promotion of the building's energy classification. Robur utilizes Triangle's motor mounting brackets in their heat-pump line. These mounts are designed with sturdiness and strength for heavy duty vibration suppression and are adaptable to efficient assembling. Robur uses Triangle's TS arms, which are custom designed for use in direct drive blowers and fans. Triangle's arms are available with three or four arms and are galvanized for corrosion-resistance.

Robur chose a fan with a large blade because of new European regulations that begin in 2013 to reduce the electric consumption of the motors (ErP 2013). Robur decided to modify their existing fan assembly in order to be compliant with this new European standard.

Due to the large pitch of the new fan, a new motor mount has to be designed to provide the necessary clearance for the fan while keeping the fan motor shaft as short as possible. Triangle responded with custom designed motor mounts with much larger curved arms than previous versions utilized. This deeper curve was a direct result of the extra-large fan blades and led to a complete re-design of the motor mounts.

Robur chose to keep the existing mounting system because they've had positive feedback throughout their more than twenty years of business with Triangle. The new slightly different blade was a great project for Triangle to modify and adjust the mounting system to fit with the new layout.
