Inverter technology makes swimming pool heat pump achieve an extremely high COP. With variable running speed basing on actual heating or cooling requirements, when pool temperature is getting close to setpoint, it heats up the pools at lower speed which offers higher COP and quieter operation. Laswim DC inverter heat pump helps to save big running cost and provides a conformable swimming environment. Features: 1. COP up to 11 No matter its cold or warm, it will adjust the heating capacity according to the pool water. When running at 20%-25% speed, it reaches the highest COP 11. 2. Super energy saving With low-speed running, DC inverter heat pump is double energy saving than traditional on/off heat pump. 3. Silent operation Thanks to the stable DC inverter control system, DC inverter compressor and variable speed ventilator, Laswim DC inverter heat pump runs very silently and provides you a comfortable swimming environment. 4. Smart WIFI App control (Optional) With smart APP control, you can check and control your heat pump anytime and anywhere, all information is at your fingertips. 5. EEV technology 10 times flexibility to adjust the gas flow and increase COP by up to 20%. 6. Wide voltage Self-adjustment to fit in unstable power supply, therefore voltage range can be 180~260V. 7. Hot gas defrosting With Saginomiya 4-way valve for quick & efficient defrosting. 8. Twisted titanium heat exchanger 40% higher efficiency than normal titanium heat exchanger. 9. Soft starter Start from 0 Amps to rated Amps steadily. No rush to house electricity system. 10. 0~43 application temperature.
