• Eco-friendly Green Refrigerant Commercial water source heat pump BWRS35-90 adopts eco-environmentally friendly refrigerants 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. • 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. • 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 • 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 Model BWRS35-90 Refrigerant R134a Heating capacity KW 45 BTU.h 153500 Heating power input KW 11.3 Heating Running current A 26.5 Power source V/Ph/Hz 380-415/3/50 Compressor scroll Compressor qty 2 Heating COP W/W 4 Noise Db(A) 47 Net unit dimension 1000*830*728 Packing dimension 1070*860*890 Condenser（Plate heat exchanger） flow rate M3/h 7.7 Pressure drop kPa 50 Cold water inlet mm DN50 Circulation water outlet  mm DN50 Evaporator（Plate heat exchanger） Flow rate M3/h 5.8 Pressure drop kPa 50 Cold water inlet mm DN50 Circulation water outlet mm DN50 FAQ 1.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. 2.Is there any difference between the vertical buried pipe and the laid buried pipe of the ground source side pipeline of the ground source heat pump? The temperature of the ground source side of the vertical buried pipe is more stable, and the unit efficiency is higher, but the buried pipe cost will be relatively high. The temperature of the ground source side of the laying buried pipe is easily affected, which leads to a decrease in the efficiency of the unit, and occupies a large area of open space, but the cost of the buried pipe is low.
