For climates with heating and cooling needs, heat pumps offer an energy-efficient alternative to furnaces and air conditioners.
Because heat pumps move heat rather than generate heat, heat pumps can provide up to 4 times the amount of energy they consume.
In most common types of heat pumps, a compressor is used to compress the refrigerant. The very silent and efficient Rotrex compressor is perfect for compressing the refrigerant, due to its high inherent efficiency.
Where excess heat or sunlight is available, a new possibility for using the highly efficient Rotrex traction drive opens up: If the heat is used to evaporate a media, a turbine or expander can be directly connected to the impeller, allowing the excess heat to power the compressor. The patented traction drive technology makes the necessary very high speeds of the turbine shaft possible.
