40kW 380V 3 Phase Dual-System Geothermal Heat Pump for Commercial Buildings
40kW commercial geothermal heat pump
,380V 3 phase ground source heat pump
,dual-system geothermal heat pump for buildings
Powered by twin commercial-grade Gree rotary compressors operating on 380V/3Ph power, the RFJ-WW-40X delivers 40 kW of continuous thermal output. The dual independent refrigerant circuits allow staged capacity modulation for optimal part-load energy efficiency while providing critical operational redundancy for large commercial heating facilities.
By extracting natural heat stored in subsoil or ground water (maintained at a stable 4°C to 12°C year-round), this geothermal heat pump provides clean space heating while reducing energy costs by up to 60% compared to traditional boilers. It transfers renewable energy directly into indoor radiant loops, drastically lowering building carbon emissions.
Equipped with high-efficiency brazed plate heat exchangers on both ground-source and indoor load sides for rapid thermal exchange. An integrated water flow switch actively protects system hydraulics against low-flow freezing conditions, while the pump-free casing allows engineering contractors to select external pumps tailored to exact system head loss.
- Standard Included Components: Dual Gree rotary compressors, dual brazed plate heat exchangers, built-in water flow switch, and simplified digital controller.
- System Design Notes:
- Heating-Only Configuration: Dedicated single-function thermal generator optimized for hydronic heating applications.
- External Pump Requirement: Built without an internal water pump; external circulating pumps must be integrated into the system loops.
Ideal for large commercial centers, hotels, office complexes, and residential developments using underfloor heating grids, hydronic radiators, or fan coil units.
Connects to four main geothermal ground loop sources: vertical rock boreholes (90-200m depth), shallow ground water wells, submerged lake heat collectors, or horizontal surface soil piping (80-100cm depth).
Replaces fossil-fuel boilers or direct electric heaters in green housing projects, greenhouses, and industrial plants to lower seasonal operating costs.

Ruifujie is an established supplier and global B2B exporter in the HVAC and commercial refrigeration industry, bringing over two decades of technical expertise to clients worldwide. Our catalog encompasses scroll, reciprocating, rotary, semi-hermetic, and screw compressors, alongside geothermal heat pumps, blast freezing equipment, and cold storage units. Backed by full OEM/ODM custom development and strict quality testing protocols, Ruifujie serves engineering contractors and equipment distributors across the United States, Russia, the United Kingdom, the United Arab Emirates, Saudi Arabia, and over 60 countries worldwide.
A: Instead of generating heat via electric resistance, it absorbs free, renewable energy stored in subsoil or ground water (4°C-12°C year-round) via an anti-freeze collector loop and transfers it indoors, cutting utility costs by up to 60%.
A: The dual-system architecture utilizes two independent Gree rotary compressor circuits. This allows the unit to run on a single circuit during partial thermal loads to save electricity, while providing continuous system backup protection.
A: It is fully compatible with four geothermal loop systems: deep rock boreholes, open/closed ground water wells, submerged lake collectors, or shallow horizontal ground soil loops.
A: Sample units are charged upfront, and the sample fee is fully refunded once your subsequent bulk production order meets the required volume threshold.
A: All heat pump products across our entire catalog are covered by a standard 1-year factory warranty.
