50KW 380V R32 Dual System Ground Source Heat Pump

Engineered for high-demand commercial and industrial heating applications, the RFJ-WW-50X ground source heat pump features a dual-circuit setup powered by two heavy-duty Gree rotary compressors. The dual-system architecture allows automated 50% and 100% capacity staging to match fluctuating heating demands, significantly reducing electrical peak loads while providing built-in circuit redundancy for continuous operational uptime.

By tapping into constant underground earth temperatures (4°C to 12°C), this 50 kW ground source heat pump delivers clean hydronic thermal energy at a fraction of the cost of legacy fossil-fuel boilers or electric resistance heating networks. The unit cuts seasonal heating energy bills by up to 60%, offering a low-carbon energy solution that helps large commercial facilities lower operating expenses and achieve green building compliance.

Equipped with dual-side brazed plate heat exchangers, the RFJ-WW-50X optimizes thermal energy transfer between the ground collector loop and the indoor heating system. An integrated internal water flow switch safeguards the heat exchangers against freeze-up or low-flow damage. Manufactured without an internal circulation pump, the unit gives MEP engineers full freedom to specify external pump stations tailored to the exact hydraulic head of the site.
