Ebm-papst says it has developed a new EC fan line that ensures efficient, economical, and quiet operation. The size 500 axial fans from ebm-papst were specially engineered for use in outdoor heat pumps and have now been optimized for energy efficiency and noise reduction.
Regal Beloit says its new DEC Star system combines patented technologies of Genteq® HEB blowers and axial flux Genteq motors to improve efficiency for HVAC appliances, and reduce input wattage by 15 to 35% over standard blowers with traditional ECM motors.
Continental Fan says its FADP Fiberglass Panel Fans provide aerodynamically superior performance in a direct drive design. The FADP fan is ideal for corrosive environments or contaminated air stream applications.
Rosenberg has released four new axial fans, complete with shrouds and finger guards for HVAC condenser applications. The fans are designed with profiled aluminum blades with winglet tips that aim to reduce noise and improve fan performance.
Continental Fan has introduced the new DXG & DXP AC Motorized Axials. The coupling of the motor and impeller minimizes space requirements and provides for vibration free operation. Both motor and impeller are located directly in the air stream, providing excellent heat dissipation and efficient motor cooling, according to the company.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
