  • A quantum leap in energy efficiency for house heating
    For decades it has been common practice to use circulation pumps in household central heating systems. The advantages are simple: a low noise level, an efficient wet runner motor and a maintenance-free design. Dr. Holger Krasmann, General Manager of the WILO Pump Group in Germany, explains the development of the technology and predicts its dramatic effects on energy consumption.
  • Pump technology can reduce energy consumption of HVAC systems
    WILO USA’s new energy efficient pump technology can reduce energy consumption of HVAC systems, using up to 80% less electricity than single-speed circulators.
  • Energy savings in pump systems
    In this third in a series of articles on energy savings in pumps, Hans Vogelesang of PumpSupport considers the factors that should be borne in mind when designing piping systems. Many issues should be examined to ensure that a system will operate in an energy-efficient manner, both at design capacity and at partial load.
  • Control crucial to copper rod quality
    Dieter Klefoth and Stefan Seemer look at a demand-based speed-controlled pump system. This, with new submersible pumps together with state-of-the-art control systems, has been instrumental in lowering the power consumption and raising the reliability and quality of a copper wire manufacturing process in Germany.
  • Climate change, the water cycle and AC drives
    Climate change, increasing demands on water due to global urbanization and the legal obligations under the EUs Water Framework Directive are making the water sector an attractive place for technologies that can help reduce costs and contribute to reducing the effects of climate change. Here Heikki J. Kervinen of ABB discusses the influential role AC drives can play in meeting these challenges.

Wilo HVAC pump requires less power

26 May 2010

Wilo has introduced the Wilo-Star-Z NOVA, a circulation pump designed for consumer HVAC systems.

The Wilo-Star-Z NOVA circulation pump has an energy-efficient synchronous motor and compared to older circulation pumps, the Wilo-Star-Z NOVA requires up to 80% less power, i.e. only 2 to 4.5 Watt. This also reduces the operating temperature of the motor and thus of the entire pump. The motor is also compatible with all commercially available pump types, so that an existing circulation pump can quickly and easily be replaced.
 

The Wilo-Star-Z NOVA can be applied at water hardnesses of up to 20° Grad deutscher Wasserhärte (a German measurement of water hardness).
