● Eco Friendly Refrigerant R32  Compared to the refrigerants widely used today, such as R22 and R41 0A, R32 has a global warming potential that is two-third lower. R32 is also remarkable for its small environmen tal impact, which speeds up its popularity in the industry. ● Four-season Swimming With the full DC inverter technology and the larger heat exchanger, OSB INVERTER POOL HEAT PUMP is able to run stably in a wide ambient temperature range from -10~43°C. lt is a cost effective way to extend the pool heating period to four seasons. OSB INVERTER POOL HEAT PUMP can also connect with Photovoltaic (PV) system and directly use the electricity generated during operation. It can achieve 100% free running when solar energy is the strongest in summer. ● Full DC Inverter Technology Unlike a traditional heat pump with a single-speed compressor which by switching on and off periodically to adjust the performance of the heating & cooling, a full inverter heat pump uses a variable speed compressor which can automatically adjust the output needed at the lowest consumption of power and maintain the best temperature at different climatic conditions. When the heating demand is high, the inverter compressor and the fan motor will start running at a high speed, inversely, they will run at a low speed. Water temp. accuracy can be down to 0.1℃ ● Super Silence Thanks to patented silent-design, OSB Inverter Pool Heat Pump makes a quieter swimming environment and friendly neighborhood for you. The sound level is only 43dB. ● Smart Mobile WIFI APP Control On a business trip or a holiday tr avel? Set and check your pool temperature via the app in your smart phone. The pool temperature is just at your fingertips. The intelligent controller is used to realize the linkage control between the heat pump unit and the terminal application to improve the operation efficiency. Through the WIFI APP, users can operate their devices from their smartphones anytime and anywhere. ● Unique Protection Functions  There are multiple intelligent protections functions of OSB POOL HEAT PUMP: ground protection, temp differential protection, losting-phase protection, high/low voltage protection, water flow protection, frost protection, temp sensor fault protection. ● OEM & ODM & ONE-STOP solution OSB heat pump company has more than 23 years of OEM ODM experience, and has joined in many household and commercial customized projects. We accept OEM for logo, style, packaging and material. OSB can also provide ONE-STOP solution service for pool accessories (water pump /sand filter/ pool cover, etc.). ● Connection diagram ● Wide Occasion Application  OSB POOL HEAT PUMP is applicable to swimming pool, jacuzzi Spa, hot spring, or fish cultivation, etc,. Also can be OEM for different household & commercial projects. ● Less Installation Space Optional With the innovative vertical exhaust design. OSB VERTICAL POOL HEAT PUMP can be installed next to any pool even though in tight space. ● Less Installation Space Optional With the innovative vertical exhaust design.
