The SwimDrive with built-in vector control allows total control over the pump and therefore the water flow. In spas, hot tubs and whirlpool baths the efficient single All-In-One-Pump™ replaces the 24/7 cycle pump, the filtration pump and the jet pump with simplified pipe work. The 2.5 inch (63.5mm) diameter of the SwimDrive heat exchanger does not restrict the passage of water through it and can be connected to any pipe diameter between 1 inch (25.4mm) and 2.5 inch (63.5mm) using suitable union fittings.

The water that flows through the SwimDrive inverter cools the inverter even when the flowing water temperature is 40°C and the recovered heat energy is collected by the flowing water. This heat energy recovery helps to reduce the water heating cost.

Technology


The global increase in energy demand and the debate about climate change have placed power engineering technology in the spot-light and at the forefront of discussions. New technologies in this sector are being researched in order to effectively and efficiently use the available resources. In water circulation and pumping applications in spas, hot tubs and whirlpool baths, where there is a large dynamic water head (frictional losses due to water flow in pipe work), significant energy savings can be made by using the vector controlled variable speed drive employed in SwimDrive. In all these applications the power consumption is proportional to the cube of the motor speed, commonly referred to as a ‘Cube Law’. According to this, even at a modest reduction in pump speed with SwimDrive, the energy savings become significant.
