Description
Dual-System Independent Circuit Architecture
The RFJ-WW-30X ground-source heat pump features a dual-system configuration with two completely independent refrigerant circuits. This dual-circuit design enables automatic staged operation, allowing the unit to run a single circuit during mild weather for partial-load energy savings, while providing 100% operational redundancy to ensure continuous heating uptime if one circuit undergoes servicing.
High-Efficiency Dual GMCC Rotary Compressors
Driven by two performance-matched GMCC rotary compressors, the RFJ-WW-30X delivers a reliable 30 kW nominal heating capacity. Utilizing constant subsoil temperatures (4°C to 12°C), this dual-compressor ground-source heat pump lowers seasonal operating costs by up to 60% compared to conventional gas boilers or electric resistance heating networks.
Dual-Side Plate Heat Exchangers & Flow Protection
Equipped with compact dual-side brazed plate heat exchangers, the unit optimizes refrigerant-to-water heat transfer for both the earth loop and indoor hydronic circuits. A built-in internal water flow switch continuously monitors liquid movement, protecting internal components against low-flow or freezing conditions. Designed without an internal water pump, the system allows MEP engineers full freedom to specify external primary/secondary pump stations tailored to site-specific pressure drops.
Applications
Commercial Properties
Delivers baseline hydronic space heating for medium-sized office buildings, retail centers, and public facilities.
Multi-Family Housing
Supplies centralized radiant floor heating and domestic hot water for small apartment blocks and residential developments.
Aquaculture Climate Control
Provides stable 30 kW thermal management for commercial greenhouses, poultry housing, and temperature-controlled aquaculture ponds.
