Product Description
Detailed Specifications & Features
30kW R32 R410A Dual-System Ground Source Heat Pump
Product Advantages
Dual Independent Refrigerant Circuits & GMCC Rotary Compressors
Built with a dual-system architecture powered by twin GMCC rotary compressors, the RFJ-WW-30X delivers 30 kW of thermal capacity. Operating on 380V/3Ph power, the dual independent circuits allow staged capacity regulation to optimize part-load energy efficiency while providing operational redundancy for large hydronic heating projects.

Renewable Geothermal Energy Efficiency
By extracting naturally stored heat from subsoil or underground water maintained at a stable 4°C to 12°C year-round, this ground-source heat pump delivers clean hydronic space heating while reducing energy costs by up to 60% compared to traditional boilers. It transfers renewable energy from the earth directly into indoor underfloor loops or radiators, significantly cutting greenhouse emissions.

Dual Plate Exchangers & Built-in Flow Safety Protection
Featuring high-efficiency brazed plate heat exchangers on both ground-loop and indoor load sides, this unit optimizes heat transfer across closed or open ground loops. An integrated water flow switch actively protects against low-flow freezing, while the pump-free casing gives engineers complete freedom to select external circulation pumps suited to exact piping head loss.

- Standard Included Components: Dual GMCC 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: Unit does not contain an internal water pump; external circulating pumps must be integrated into the system loops.
Applications
- Commercial & Large Residential Space Heating
Designed for large villas, commercial complexes, and agricultural buildings utilizing underfloor heating grids, hydronic radiators, or fan coil units. - Multiple Geothermal Heat Source Integration
Compatible with all four primary geothermal collector loops: deep rock boreholes (90-200m depth), shallow ground water wells, submerged lake collectors, or horizontal surface soil loops (80-100cm depth). - Green Building Energy Upgrades
Replaces fossil-fuel boilers and direct electric heaters to cut operating expenses while meeting low-carbon environmental standards.

Frequently Asked Questions
Q1: How does the dual-system structure of model RFJ-WW-30X enhance performance?
A: The dual-system architecture utilizes two independent GMCC compressor circuits. This allows the unit to stage operation during partial heating loads, preserving energy efficiency while providing continuous backup protection.
Q2: Which ground-source energy collectors can be paired with this 30 kW heat pump?
A: It connects seamlessly to deep rock boreholes, open or closed ground water wells, submerged lake heat collectors, or shallow horizontal ground soil loops filled with anti-freeze fluid.
Q3: How does the integrated water flow switch protect the internal plate heat exchangers?
A: The built-in water flow switch continuously monitors fluid circulation on both loops. If water flow drops below a safe threshold, the switch automatically halts operation to prevent icing and structural damage inside the plate exchangers.
Q4: Do you offer OEM branding and customized nameplates for volume orders?
A: Yes, we fully support custom LOGO printing and multi-language nameplate customization for B2B commercial production orders.
Q5: What are your export packaging standards and refrigerant handling policies?
A: All heat pumps are packed in protective wooden cases. Sea freight shipments are shipped pre-charged with refrigerant, whereas air freight shipments exclude refrigerant to satisfy aviation transport safety standards.
