• Eco-friendly Green Refrigerant R32 • Equipped with Inverter Technology Our inverter is an energy saving technology that efficiently controls the motor speed and reduces energy consumption by up to 30%. Rather than expending energy by starting and stopping, the inverter adjusts the speed of the motor so that it runs continuously and more efficiently in the long run. • Smart Wi-Fi Control 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.  • Low Noise Running A fully enclosed cabinet is specially designed for the compressor so that the running noise can be kept inside and the noise of the whole unit can maintain very low. • Stable temp - Consistency regardless of the time or temp outside All weather operation is stable without being influenced by weather. Deliver heating, cooling and hot water in all climates. • Wide & Flexible Application Use for heating, cooling, and domestic hot water. There are also a variety of combination modes. • Module Combination Design This design is suitable for commercial, industrial, agricultural places with large hot water demands. One central controller is able to control 16 modular units. • GSHP External Connection Methods • Module Combination Design This design is suitable for commercial, industrial, agricultural places with large hot water demands. One central controller is able to control 16 modular units. • Quality-guranteed Components Use international famous brand components equipping Model BGB1I-135 Rated cooling capacity KW 8.4~16.5 Cooling power input KW 1.16~3.75 Running current(cooling) A 5.4~17.1 Maximum operating current A 33.5 Power supply V/PH/HZ 220/1/50 COP 4.4~7.4 Using side water flow rate 　m³/h 2.83 Ground source side water flow rate m³/h 4.82 Water proof class IPX4 Water pressure drop Inch 1” Water flow volume dB(A) 62 Net weight kg 136 FAQ 1.Is the use and operation of air source heat pump unit easy? It is very easy. The whole unit adopts automatic intelligent control system. The user only needs to turn on the power supply for the first time, and fully realize the automatic operation in the later use process. When the water temperature reaches the user's specified temperature, the system automatically starts up and runs when the water temperature is lower than the user's specified water temperature, so that hot water can be available 24 hours a day without waiting. 2.How deep is the pipes of ground source heat pump buried? Laying buried pipes generally require a depth of 2 meters, and vertical buried pipes require 100 meters deep or more. As for the tiled area, you need to consult your installation engineer for advice, because the geology of each area is different, and the parameters are different. 3. What’s your after- sales policy?
