Calorex IPAC Heat pumps

Calorex IPAC Inverter Heat Pumps

Inverter technology allows the speed of the heat pump to reduce whenever the pool needs less than the full output, matching heat output to exactly the heat required. This not only gives you lower running costs, but reduces sound levels to a whisper and eliminates the massive inrush currents associated with on/off heat pumps.
