Ultra-Quiet Performance That Changes the Pool Experience
Nobody wants a noisy heat pump dominating the backyard. The Aqua X20 runs at an incredibly low noise level, with the compressor and fan operating at very low speeds while maintaining water temperature. At around 36.6dB(A) during low-speed operation and 41.9dB(A) under standard operation, it’s dramatically quieter than traditional pool heat pumps. You can swim, entertain, or relax outside without constant background noise.

Massive Energy Savings With COP20 Efficiency
The Aqua X20 is designed for customers who want premium performance without excessive running costs. Its intelligent Full-inverter system continuously adjusts compressor speed and gas flow depending on pool demand, delivering a Coefficient of Performance (COP) of up to 20 — around 30% higher than standard heat pumps. That means lower electricity usage while still keeping your pool comfortable year-round.

Built for Harsh Australian Conditions
Summer heat can push standard pool equipment to its limits. The Aqua X20 is engineered to keep cooling and heating efficiently even in extreme temperatures up to 43°C. Whether you're dealing with scorching summer days or cooler months, this system is designed to keep pool temperatures stable across changing conditions.

Advanced Lightning Heat Exchange Technology
Fairland’s next-generation Lightning Heat Exchange Technology completely reworks traditional titanium heat exchanger design. The upgraded system expands heat exchange surface area by 30%, helping the unit transfer heat faster and more efficiently. Combined with the high-efficiency 3D heat exchange system, you get stronger performance, faster pool temperature recovery, and improved overall efficiency.
Smart Full-Inverter Technology
Unlike fixed-speed heat pumps that constantly turn on and off, the TurboSilence Full-inverter system intelligently adjusts compressor and fan speed depending on your pool’s needs. This reduces power consumption, improves temperature stability, extends equipment life, and dramatically lowers operational noise. The proprietary Fairland control system continuously balances performance and efficiency automatically in the background.
Construction & Design
The Aqua X20 combines a high-efficiency inverter compressor with Fairland’s proprietary Full-inverter control platform and advanced 3D heat exchange system. Its Lightning titanium heat exchanger improves heat transfer performance while offering strong resistance to pool water conditions. The stainless steel finish gives the unit a clean, modern appearance while maintaining durability for outdoor installation.
