Product Description
Detailed Specifications & Features
50kW 380V Dual-System Geothermal Heat Pump With Gree Rotary Compressor
Product Advantages
Dual-System Gree Rotary Compressors
Equipped with high-performance dual Gree rotary compressors operating on a 380V/3Ph supply, this 50 kW unit utilizes two completely independent refrigerant circuits. This dual-system design enables dynamic stage-loading under variable heating demands, maximizing seasonal energy efficiency while providing built-in operational redundancy for commercial projects.
Four Geothermal Energy Sources & High-Efficiency Sustainability
By tapping into constant underground thermal energy maintained between 4°C and 12°C year-round, the system extracts renewable solar heat stored in rock layers, ground water, lakes, or surface soil. It reduces heating energy consumption by up to 60% and significantly cuts CO2 emissions compared to traditional gas or electric boilers.
Dual Plate Exchangers & Built-in Flow Safety Protection
Featuring high-efficiency brazed plate heat exchangers on both ground-loop and load sides, the unit ensures rapid, low-loss thermal exchange. An integrated water flow switch actively monitors system fluid velocity to protect against low-flow freezing conditions, while the pump-free casing design allows customized external pump sizing.
Standard Included Components:
Dual Gree rotary compressors, dual brazed plate heat exchangers, built-in water flow safety switch, and simplified digital controller.
- System Design Notes:
- Heating-Only Configuration: Dedicated single-function thermal generator optimized for large-scale hydronic space heating.
- External Pump Requirement: Built without an internal water pump; external circulating pumps must be integrated into the system loops.
Applications
Commercial & Large Industrial Hydronic Heating
Ideal for commercial centers, hotels, office buildings, cleanrooms, and large agricultural facilities utilizing underfloor heating grids, hydronic radiators, or fan coil units.
Multi-Source Geothermal Energy Loops
Compatible with four geothermal source loops: deep rock boreholes (90-200m depth), shallow ground water wells, submerged lake heat collectors, or horizontal surface soil piping (80-100cm depth).
Green Building Decarbonization
Engineered to replace fossil-fuel boilers and direct electric heaters, slashing operating expenses and greenhouse gas emissions.

Frequently Asked Questions
Q1: How does a water-to-water geothermal heat pump transfer underground solar energy into a building?
A: It circulates anti-freeze fluid through buried collector loops to absorb solar heat naturally stored in subsoil or ground water (4°C-12°C). The refrigerant cycle compresses this low-temperature heat into high-temperature thermal energy, which is delivered via plate heat exchangers into indoor underfloor loops, radiators, or hot water tanks.
Q2: What operational benefits does the 50 kW dual-system architecture offer for commercial facilities?
A: The dual Gree compressor structure provides two independent refrigerant loops. During milder weather or partial loads, the unit runs on a single compressor circuit to minimize power draw, while engaging both circuits during peak winter conditions.
Q3: Which geothermal collector option is best suited for properties with limited land area?
A: Deep rock borehole collectors (drilled 90-200 meters deep) require a minimal footprint, making them ideal for urban commercial buildings or compact plots where horizontal soil loops are impractical.
Q4: What standard international trade terms and settlement currencies do you accept?
A: We support FOB Shenzhen and EXW trade terms, with all commercial transactions settled in USD.
Q5: What payment methods are accepted for commercial heat pump orders?
A: We support T/T (Telegraphic Transfer) and Western Union payment methods.
