• Eco-friendly Green Refrigerant To reduce carbon emission to the environment and curb global warming, O.S.B.develops R290 air to water heat pump. With many advantages such as low carbon emission and high efficiency, R290 refrigerant is recognized as a refrigerant with the most development potential in the industry, which contributes to the reduction of carbon emission and help achieve the global goal of carbon neutrality. Otherwise, there are other green refrigerants available options, such as R32, R410A, R134A • 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. • 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. • 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.  • 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. • Wide & Flexible Application Use for heating, cooling, and domestic hot water. There are also a variety of combination modes. • Unique Functions and Protections There are multiple intelligent functions: memory function/ timer/ temperature control/ malfunction detect and 4-way protections: water lack protection/ system pressure protection/ abnornmal alert/ brust protection on heat exchanger  • Quality-guranteed Components Use international famous brand components equipping • GSHP External Connection Methods Model BWRS35-80 Refrigerant R410a Rated heating capacity KW 41 BTU 139800 Rated cooling capacity KW 40 BTU 136400 COP /EER 4.4/6.4  Heating power input KW 9.4 Cooling power input KW 6.3 Power supply V/Ph/Hz 380/3/50~60 Max outlet water temp ° C 50 Applicable ambient temp ° C 8~43 Water flow volume M3/H 7 Water connections inch 1.5'' water pressure drop Kpa 50 Compressor qty Pc 2 Container loading qty 20/40/40HQ 20/46/46
