Description
Eco-Friendly R32 / R410A Low-Emission Operation
Engineered to support sustainable building energy standards, the RFJ-WW-40X offers full compatibility with R32 and R410A refrigerants. Selecting low-GWP R32 enhances overall thermodynamic efficiency while significantly reducing direct carbon emissions, helping commercial property owners and MEP contractors meet strict green building certifications and regional environmental regulations.
Dual Independent Circuit Architecture
Featuring a 2-stage dual-system configuration, the RFJ-WW-40X operates two complete, independent refrigerant circuits. This architecture enables smart partial-load staging during mild weather to maximize seasonal energy efficiency while providing 100% operational redundancy to ensure uninterrupted space heating during routine system maintenance.
High-Turbulence Dual Plate Heat Exchangers & Flow Protection
Outfitted with dual-side brazed plate heat exchangers, the unit optimizes heat transfer between the ground loop antifreeze mixture and the building's hydronic network. An integrated internal water flow switch continuously monitors liquid movement to protect internal components against freeze-ups or low-flow conditions.
