Fans for cooling and ventilation have been optimised again and again in terms of their power, flexibility and above all their energy consumption: With improved aerodynamics and intelligent drive systems, efficient fans save 43,000,000 kWh across Europe every single year. More advanced designs such as radial fans will in future make it possible to achieve efficiency levels of up to 80%.
Modern pump systems allow industry to achieve high energy-saving effects: highly efficient motors, frequency converters with a variable rotational speed, hydraulic equalisation of the hot water network and temperature-dependent regulation help to deliver a 50% lower level of consumption.
Many lift components can have a positive impact on how much energy a lift system consumes: intelligently controlled lift car lighting, display elements and door actuator reduce energy consumption when the lift is at a standstill. Drives with a higher level of efficiency have a positive influence on energy consumption during travel and a smoke extraction opening in line with requirements minimises heat losses from the building through the lift shaft. The result: a reduction in energy consumption of up to 45%.
