Power Rinnai TRX02CXIN 22 GPM / 398,000 BTU 2-Unit SENSEI CX Tankless Rack (Indoor, Wall-Mount)
Replace bulky tanks with a compact, preassembled rack that delivers big hot-water output. The Rinnai TRX02CXIN combines two SENSEI CX199i condensing tankless units on a low-profile aluminum frame—ideal for restaurants, hospitality, and light commercial change-outs. Expect up to 10.8 GPM @ 70°F rise (two units) with 97% thermal efficiency, plus built-in cascade controls for balanced runtime and redundancy. Wall mounting frees floor space, and 1inch water / 1-1/2 inch gas trunks streamline tie-ins.

Save Energy & Lower Operating Costs
Each CX199i is a super-high-efficiency condensing unit rated 97% thermal efficiency (UEF up to 0.98), helping trim gas use versus atmospheric tanks. Condensing heat recovery plus electronic modulation keeps outlet temperature steady across varying demand—without wasting fuel at idle.
Everyday Performance You Can Feel
The two-unit rack delivers up to 10.8 GPM @ 70 °F and 7.6 GPM @ 100 °F rise—great for dish rooms, showers, and back-to-back draws. At low temperature rises, combined output can approach ~22 GPM (two 11.0 GPM units), supporting large intermittent peaks.*
Durable Materials, Easier Care
A powder-coated aluminum frame resists corrosion; the water header uses rigid copper, and the gas trunk is Schedule-40 steel for robust service connections. CX-series safety systems include flame-failure, overheat, blocked-flue, and automatic freeze protection up to 10,100 ft altitude.
Installer-Friendly, Preassembled Rack
The rack ships with cascade controls pre-installed and an offset wall bracket to mount over existing conduit or piping. Tie into 1" MNPT hot/cold and 1-1/2" MNPT gas trunks, provide 120 V power (max 8 A), and follow the spec’d centers for fast, repeatable installs. A leg kit is available where floor support is preferred.
Sized Right For Tight Mechanical Spaces
The compact envelope—about 39" W × 38.5" H × 35" D—uses zero floor space and reduces wall takeoff versus site-built manifolds. Plan clearances and service access per the diagram to keep valves, drains, and traps accessible.
Flexible Venting & Control Options
Vent each unit with 2? or 3? PVC/CPVC/PP twin-pipe or a 3?×5? concentric kit; indoor common-venting is supported where code allows. Typical max lengths: up to 75 ft (2?) or 150 ft (3?), layout-dependent. Cascade up to 24 units across racks as your needs grow.
Redundancy That Keeps You Running
With two independent CX199i engines, the system shares load for longer life and keeps hot water online if one unit is down for service. Integrated cascade logic balances runtime automatically—no external controller required.
